Management of Corn Diseases ndash Fungicide Efficacy for Control of Corn Diseases (April 2015) The Corn Disease Working Group (CDWG) has developed the following information Efficacy ratings for each fungicide listed in the table were determined by field testing the materials overmultiple years and locations by members of the committee Efficacy ratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increasesobtained from product application Efficacy depends upon proper application timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among products in field testsand are based on a single application of the labeled rate as listed in the table The table includes systemic fungicides available that have been tested over multiple years and locations This table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeledfor use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US corn belt and may not always reflect fungicide efficacy observed in Arkansas

1 Additional fungicides are labeled for disease on corn including contact fungicides such as chlorothalonilCertain fungicides may be available for diseases not listed in the table including Gibberella and Fusariumear rot Application of Proline 480 SC for use on ear rots requires a FIFRA Section 2(ee) and is onlyapproved for use in Illinois Indiana Iowa Louisiana Maryland Michigan Mississippi North Dakota OhioPennsylvania and Virginia
2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

Management of Soybean Diseases ndash Fungicide Efficacy for Control of Foliar Soybean Diseases (April 2015) The North Central Regional Committee on Soybean Diseases (NCERAshy137) has developed the following information on foliar fungicide efficacy for control of major foliar soybean diseases in theUnited States Efficacy ratings for each fungicide listed in the table were determined by fieldshytesting the materials over multiple years and locations by the members of the committee Efficacyratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increases obtained from product application Efficacy depends upon proper applicashytion timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of applicationDifferences in efficacy among fungicide products were determined by direct comparisons among products in field tests and are based on a single application of the labeled rate as listed in thetable unless otherwise noted This table includes systemic fungicides available that have been tested over multiple years and locations The table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeled for use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US soybean belt and may not always reflect fungicide efficacy observed in Arkansas

1 Multiple fungicides are labeled for soybean rust only powdery mildew and alternaria leaf spot including tebuconazole (multiple products) and Laredo (myclobutanil) Contact fungicides such aschlorothalonil may also be labeled for use
2 Cercospora leaf blight efficacy relies on accurate application timing and standard R3 application timings may not provide adequate disease control Fungicide efficacy may improve with earlier orlater applications Fungicides with a solo or mixed Qol or MBC mode of action may not be effective in areas where Qol or MBC resistance has been detected in the fungal population that causesCercospora leaf blight
3 In areas where Qolshyfungicide resistant isolates of the frogeye leaf spot pathogen are not present Qol fungicides may be more effective than indicated in this table 4 Harvest restrictions are listed for soybean harvested for grain Restrictions may vary for other types of soybean (edamame etc) and soybean for other uses such as forage or fodder 5 Multiple generic products containing this mode of action may also be labeled in some states
Many products have specific use restrictions about the amount of active ingredient that can be applied within a period of time or the amount of sequential applications that can occur Please readand follow all specific use restrictions prior to fungicide use This information is provided only as a guide It is the responsibility of the pesticide applicator by law to read and follow all current labeldirections Reference to products in this publication is not intended to be an endorsement to the exclusion of others that may be similar Persons using such products assume responsibility fortheir use in accordance with current directions of the manufacturer Members or participants in the NCERAshy212 or NCERAshy208 group assume no liability resulting from the use of these products

Efficacy of Fungicides for Wheat Disease Control Based on Appropriate Application Timing (Revised 3shy31shy15) The North Central Regional Committee on Management of Small Grain Diseases (NCERAshy184) has developed the following information on fungicide efficacy for control of certain foliardiseases of wheat for use by the grain production industry in the US Efficacy ratings for each fungicide listed in the table were determined by field testing the materials over multipleyears and locations by the members of the committee Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among productsin field tests and are based on a single application of the labeled rate as listed in the table The table includes the most widely marketed products and is not intended to be a list of alllabeled products

Management of Corn Diseases ndash Fungicide Efficacy for Control of Corn Diseases (April 2015) The Corn Disease Working Group (CDWG) has developed the following information Efficacy ratings for each fungicide listed in the table were determined by field testing the materials overmultiple years and locations by members of the committee Efficacy ratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increasesobtained from product application Efficacy depends upon proper application timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among products in field testsand are based on a single application of the labeled rate as listed in the table The table includes systemic fungicides available that have been tested over multiple years and locations This table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeledfor use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US corn belt and may not always reflect fungicide efficacy observed in Arkansas

1 Additional fungicides are labeled for disease on corn including contact fungicides such as chlorothalonilCertain fungicides may be available for diseases not listed in the table including Gibberella and Fusariumear rot Application of Proline 480 SC for use on ear rots requires a FIFRA Section 2(ee) and is onlyapproved for use in Illinois Indiana Iowa Louisiana Maryland Michigan Mississippi North Dakota OhioPennsylvania and Virginia
2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

NOTE Metalaxyl and mefenoxam have activity against Pythium and Phytophthora fungi while all others listed are more active against Rhizoctonia Fusarium and various fungi A combination of the two chemistries provides broadest spectrum control If an inoculant is to be used it should be applied after fungicide seed treatments have dried andor right before plantingSeed treatments often have not resulted in improved stands or yields in University trials unless lessshythanshyoptimum planting conditions are prevalent (early planting heavy clay soils cool wetconditions etc)

Management of Soybean Diseases ndash Fungicide Efficacy for Control of Foliar Soybean Diseases (April 2015) The North Central Regional Committee on Soybean Diseases (NCERAshy137) has developed the following information on foliar fungicide efficacy for control of major foliar soybean diseases in theUnited States Efficacy ratings for each fungicide listed in the table were determined by fieldshytesting the materials over multiple years and locations by the members of the committee Efficacyratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increases obtained from product application Efficacy depends upon proper applicashytion timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of applicationDifferences in efficacy among fungicide products were determined by direct comparisons among products in field tests and are based on a single application of the labeled rate as listed in thetable unless otherwise noted This table includes systemic fungicides available that have been tested over multiple years and locations The table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeled for use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US soybean belt and may not always reflect fungicide efficacy observed in Arkansas

1 Multiple fungicides are labeled for soybean rust only powdery mildew and alternaria leaf spot including tebuconazole (multiple products) and Laredo (myclobutanil) Contact fungicides such aschlorothalonil may also be labeled for use
2 Cercospora leaf blight efficacy relies on accurate application timing and standard R3 application timings may not provide adequate disease control Fungicide efficacy may improve with earlier orlater applications Fungicides with a solo or mixed Qol or MBC mode of action may not be effective in areas where Qol or MBC resistance has been detected in the fungal population that causesCercospora leaf blight
3 In areas where Qolshyfungicide resistant isolates of the frogeye leaf spot pathogen are not present Qol fungicides may be more effective than indicated in this table 4 Harvest restrictions are listed for soybean harvested for grain Restrictions may vary for other types of soybean (edamame etc) and soybean for other uses such as forage or fodder 5 Multiple generic products containing this mode of action may also be labeled in some states
Many products have specific use restrictions about the amount of active ingredient that can be applied within a period of time or the amount of sequential applications that can occur Please readand follow all specific use restrictions prior to fungicide use This information is provided only as a guide It is the responsibility of the pesticide applicator by law to read and follow all current labeldirections Reference to products in this publication is not intended to be an endorsement to the exclusion of others that may be similar Persons using such products assume responsibility fortheir use in accordance with current directions of the manufacturer Members or participants in the NCERAshy212 or NCERAshy208 group assume no liability resulting from the use of these products

Efficacy of Fungicides for Wheat Disease Control Based on Appropriate Application Timing (Revised 3shy31shy15) The North Central Regional Committee on Management of Small Grain Diseases (NCERAshy184) has developed the following information on fungicide efficacy for control of certain foliardiseases of wheat for use by the grain production industry in the US Efficacy ratings for each fungicide listed in the table were determined by field testing the materials over multipleyears and locations by the members of the committee Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among productsin field tests and are based on a single application of the labeled rate as listed in the table The table includes the most widely marketed products and is not intended to be a list of alllabeled products

Management of Corn Diseases ndash Fungicide Efficacy for Control of Corn Diseases (April 2015) The Corn Disease Working Group (CDWG) has developed the following information Efficacy ratings for each fungicide listed in the table were determined by field testing the materials overmultiple years and locations by members of the committee Efficacy ratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increasesobtained from product application Efficacy depends upon proper application timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among products in field testsand are based on a single application of the labeled rate as listed in the table The table includes systemic fungicides available that have been tested over multiple years and locations This table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeledfor use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US corn belt and may not always reflect fungicide efficacy observed in Arkansas

1 Additional fungicides are labeled for disease on corn including contact fungicides such as chlorothalonilCertain fungicides may be available for diseases not listed in the table including Gibberella and Fusariumear rot Application of Proline 480 SC for use on ear rots requires a FIFRA Section 2(ee) and is onlyapproved for use in Illinois Indiana Iowa Louisiana Maryland Michigan Mississippi North Dakota OhioPennsylvania and Virginia
2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

Management of Soybean Diseases ndash Fungicide Efficacy for Control of Foliar Soybean Diseases (April 2015) The North Central Regional Committee on Soybean Diseases (NCERAshy137) has developed the following information on foliar fungicide efficacy for control of major foliar soybean diseases in theUnited States Efficacy ratings for each fungicide listed in the table were determined by fieldshytesting the materials over multiple years and locations by the members of the committee Efficacyratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increases obtained from product application Efficacy depends upon proper applicashytion timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of applicationDifferences in efficacy among fungicide products were determined by direct comparisons among products in field tests and are based on a single application of the labeled rate as listed in thetable unless otherwise noted This table includes systemic fungicides available that have been tested over multiple years and locations The table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeled for use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US soybean belt and may not always reflect fungicide efficacy observed in Arkansas

2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

Powdery Mildew of cucurbits is caused by two fungal genera Sphaerotheca and Erysiphe that can quickly (high risk) develop resistance to fungicides Use a tank mix or premix with twomodes of action (different FRAC Code numbers) and avoid sequential use of a single chemistry (same FRAC Code number) within the same season

2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

1 Multiple fungicides are labeled for soybean rust only powdery mildew and alternaria leaf spot including tebuconazole (multiple products) and Laredo (myclobutanil) Contact fungicides such aschlorothalonil may also be labeled for use
2 Cercospora leaf blight efficacy relies on accurate application timing and standard R3 application timings may not provide adequate disease control Fungicide efficacy may improve with earlier orlater applications Fungicides with a solo or mixed Qol or MBC mode of action may not be effective in areas where Qol or MBC resistance has been detected in the fungal population that causesCercospora leaf blight
3 In areas where Qolshyfungicide resistant isolates of the frogeye leaf spot pathogen are not present Qol fungicides may be more effective than indicated in this table 4 Harvest restrictions are listed for soybean harvested for grain Restrictions may vary for other types of soybean (edamame etc) and soybean for other uses such as forage or fodder 5 Multiple generic products containing this mode of action may also be labeled in some states
Many products have specific use restrictions about the amount of active ingredient that can be applied within a period of time or the amount of sequential applications that can occur Please readand follow all specific use restrictions prior to fungicide use This information is provided only as a guide It is the responsibility of the pesticide applicator by law to read and follow all current labeldirections Reference to products in this publication is not intended to be an endorsement to the exclusion of others that may be similar Persons using such products assume responsibility fortheir use in accordance with current directions of the manufacturer Members or participants in the NCERAshy212 or NCERAshy208 group assume no liability resulting from the use of these products

2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

Management of Soybean Diseases ndash Fungicide Efficacy for Control of Foliar Soybean Diseases (April 2015) The North Central Regional Committee on Soybean Diseases (NCERAshy137) has developed the following information on foliar fungicide efficacy for control of major foliar soybean diseases in theUnited States Efficacy ratings for each fungicide listed in the table were determined by fieldshytesting the materials over multiple years and locations by the members of the committee Efficacyratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increases obtained from product application Efficacy depends upon proper applicashytion timing rate and application method to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of applicationDifferences in efficacy among fungicide products were determined by direct comparisons among products in field tests and are based on a single application of the labeled rate as listed in thetable unless otherwise noted This table includes systemic fungicides available that have been tested over multiple years and locations The table is not intended to be a list of all labeled products1 Efficacy categories NR = Not Recommended P = Poor F = Fair G = Good VG = Very Good E = Excellent NL = Not Labeled for use against this disease U = Unknown efficacy or insufficient data to rank product efficacy NOTE This guideline was a composite of several field trials from multiple states across the US soybean belt and may not always reflect fungicide efficacy observed in Arkansas

1 Multiple fungicides are labeled for soybean rust only powdery mildew and alternaria leaf spot including tebuconazole (multiple products) and Laredo (myclobutanil) Contact fungicides such aschlorothalonil may also be labeled for use
2 Cercospora leaf blight efficacy relies on accurate application timing and standard R3 application timings may not provide adequate disease control Fungicide efficacy may improve with earlier orlater applications Fungicides with a solo or mixed Qol or MBC mode of action may not be effective in areas where Qol or MBC resistance has been detected in the fungal population that causesCercospora leaf blight
3 In areas where Qolshyfungicide resistant isolates of the frogeye leaf spot pathogen are not present Qol fungicides may be more effective than indicated in this table 4 Harvest restrictions are listed for soybean harvested for grain Restrictions may vary for other types of soybean (edamame etc) and soybean for other uses such as forage or fodder 5 Multiple generic products containing this mode of action may also be labeled in some states
Many products have specific use restrictions about the amount of active ingredient that can be applied within a period of time or the amount of sequential applications that can occur Please readand follow all specific use restrictions prior to fungicide use This information is provided only as a guide It is the responsibility of the pesticide applicator by law to read and follow all current labeldirections Reference to products in this publication is not intended to be an endorsement to the exclusion of others that may be similar Persons using such products assume responsibility fortheir use in accordance with current directions of the manufacturer Members or participants in the NCERAshy212 or NCERAshy208 group assume no liability resulting from the use of these products

2 Harvest restrictions are listed for field corn harvested for grain Restrictions may vary for other types of corn(sweet seed or popcorn etc) and corn for other uses such as forage or fodder A Though there is no threshold for economical use of a fungicide to control southern rust consider yieldpotential hybrid susceptibility growth stage and weather conditions when southern rust threatensGenerally fungicides with a sole strobilurin mode of action are most effective when applied before southern rust is observed and fungicides with a sole or mixed triazole mode of action are effective when appliedbefore or after rust is found in a field A fungicide application at tasseling or silking when southern rust has
been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressingdisease development however additional application may be needed for seasonshylong crop protectionField corn within two weeks from physiological maturity (ie black layer) is very unlikely to benefit from afungicide application
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur Please read and follow allspecific use restrictions prior to fungicide use This information is provided only as a guide It is the responshysibility of the pesticide applicator by law to read and follow all current label directions Reference to productsin this publication is not intended to be an endorsement to the exclusion of others that may be similarPersons using such products assume responsibility for their use in accordance with current directions ofthe manufacturer Members or participants in the CDWG assume no liability resulting from the use ofthese products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

1 Multiple fungicides are labeled for soybean rust only powdery mildew and alternaria leaf spot including tebuconazole (multiple products) and Laredo (myclobutanil) Contact fungicides such aschlorothalonil may also be labeled for use
2 Cercospora leaf blight efficacy relies on accurate application timing and standard R3 application timings may not provide adequate disease control Fungicide efficacy may improve with earlier orlater applications Fungicides with a solo or mixed Qol or MBC mode of action may not be effective in areas where Qol or MBC resistance has been detected in the fungal population that causesCercospora leaf blight
3 In areas where Qolshyfungicide resistant isolates of the frogeye leaf spot pathogen are not present Qol fungicides may be more effective than indicated in this table 4 Harvest restrictions are listed for soybean harvested for grain Restrictions may vary for other types of soybean (edamame etc) and soybean for other uses such as forage or fodder 5 Multiple generic products containing this mode of action may also be labeled in some states
Many products have specific use restrictions about the amount of active ingredient that can be applied within a period of time or the amount of sequential applications that can occur Please readand follow all specific use restrictions prior to fungicide use This information is provided only as a guide It is the responsibility of the pesticide applicator by law to read and follow all current labeldirections Reference to products in this publication is not intended to be an endorsement to the exclusion of others that may be similar Persons using such products assume responsibility fortheir use in accordance with current directions of the manufacturer Members or participants in the NCERAshy212 or NCERAshy208 group assume no liability resulting from the use of these products

Efficacy of Fungicides for Wheat Disease Control Based on Appropriate Application Timing (Revised 3shy31shy15) The North Central Regional Committee on Management of Small Grain Diseases (NCERAshy184) has developed the following information on fungicide efficacy for control of certain foliardiseases of wheat for use by the grain production industry in the US Efficacy ratings for each fungicide listed in the table were determined by field testing the materials over multipleyears and locations by the members of the committee Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among productsin field tests and are based on a single application of the labeled rate as listed in the table The table includes the most widely marketed products and is not intended to be a list of alllabeled products

PEANUT NEMATODES (Commercial Production) Terry Kirkpatrick
Nematodes are not currently a serious threat to peanut production in Arkansas therefore we do not routinely recommend nematicides even though certain products arelabeled for this use The peanut rootshyknot nematode is extremely rare in the state It is possible however that other nematode species such as the lesion nematode or thering nematode may reach economic levels in some fields If nematodes are suspected soil samples should be collected in the fall (SeptembershyOctober) and sent to theNematode Diagnostic Laboratory for analysis before the next crop is planted

Leaf Spots
Chemical Control of Leaf Spot Diseases1 In any given field circularshyshaped spots can be found on peanut leaves however these spots may not be caused by the leaf spot pathogens Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS
2 Fungicides on peanut are applied to prevent leaf spot disease development which typically begins 60 days after planting when conditions favor disease developmentFungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditions
3 Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage4 Do not make consecutive applications of the same mode of action (ie same FRAC code number) except for those applications that contain chlorothalonil in a cropping season It is recommended to tank mix fungicides with a single mode of action with chlorothalonil

Southern blight is the most common soilborne disease of peanut in Arkansas which is most active when weather conditions are hot and humid Fungicides on peanut are applied to prevent soilborne disease development which typically begins 60 days after planting when conditions favor disease development
Fungicide programs consist of repeated applications at 14 shy 21 day intervals depending on disease development and weather conditionsApply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall Applications at night when leaves are folded have been shown to improvefungicide penetration into the lower canopyDo not make consecutive applications of the same mode of action (ie FRAC group number) except for those applications that contain chlorothalonil

1Assumes proper application and typical weather Adverse conditions may decrease the performance of fungicides Fungicide performance is greatly enhanced when plants are grown usingproper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety Proper culturalpractices greatly enhance the field resistance of rice cultivars
2No thresholds have been developed for blast The presence of leaf collar andor neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatmentWater management and flood depth greatly influence the development of blast Refer to the latest variety ratings available through the county Extension office for further information All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties
NOTE ON FUNGICIDES AND OTHER RICE DISEASES We do not currently recommend fungicides for control of other rice diseases in Arkansas Current fungicides used in rice are notrecommended for bacterial panicle blight Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary

NOTE Wheat seed producers in Arkansas should always plant seed treated with one of the listed products to prevent a buildup of loose smut and Stagonospora glume blotch in the seed supplyGrowers who plant saved seed should have it treated with one of the above especially if the seed came from a field with these diseases or if either of the diseases was at epidemic levels innearby fields during the spring

Only effective as a preventative treatment for stripe rust 1 Stagonospora (glume) blotch is more effectively controlled by seed treatment fungicides because it is primarily seedborne under Arkansas conditions and foliar symptoms are difficult to scout for in thespring See Wheat Seed Treatment Table for details
2 All fields with active hot spots of stripe rust should be sprayed immediately if found prior to Feekes GS 105
WHEAT DISEASE THRESHOLDS Terry Spurlock
The following threshold system is a general guide for whether or not there is adequate disease pressure to justify fungicide use The relative susceptibility of thevariety favorable weather conditions during the spring and location in Arkansas should also be considered For current row crop information sign up for the ArkansasRow Crop Updates at wwwarkansasshycropscom or visit your local Cooperative Extension Service office

Efficacy of Fungicides for Wheat Disease Control Based on Appropriate Application Timing (Revised 3shy31shy15) The North Central Regional Committee on Management of Small Grain Diseases (NCERAshy184) has developed the following information on fungicide efficacy for control of certain foliardiseases of wheat for use by the grain production industry in the US Efficacy ratings for each fungicide listed in the table were determined by field testing the materials over multipleyears and locations by the members of the committee Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application Differences in efficacy among fungicide products were determined by direct comparisons among productsin field tests and are based on a single application of the labeled rate as listed in the table The table includes the most widely marketed products and is not intended to be a list of alllabeled products
