1. Background

GTA Member Update No.5 of 11 and No.12 of 11 sought feedback from industry on potentialchanges to grain standards for the coming season. Feedback was received from a range ofindustry sectors on the proposed changes and a range of other issues.

The GTA Standards committee met in 2011 on several occasions and reviewed feedback fromindustry. The committee recommended changes to the GTA Board and the Board has adoptedrecommendations were warranted.

This document lists changes to all Standards for implementation in 2011/12 and those issueswhere changes were not accepted. Also listed are issues potentially to be addressed in the 2012/13Standards and beyond.

2. Process for Implementation

As the 2011/12 Standards have been adopted by the GTA Board, the final Standards have beenpublished on the GTA website atwww.graintrade.org.auand are now available for industry use.

3. Changes made for implementation in the 2011/12 GTA Standards

3.1 All Cerea ls (Section 2)

A number of formatting changes have been made to all cereal Standards either on the cerealStandards charts or in the Booklets produced associated with those charts. The changes have beenfor clarification only and have not affected the previously applied Standards or tolerances forquality parameters within those Standards except where listed below.

Cereals Standards refer to all grades of the following commodities:

Wheat Barley Sorghum Triticale Oats Cereal Rye Maize

3.1.1 Visual Quality Charts All Cereals

Significant issues arose during the 2010/11 harvest regarding the different interpretationof various subjective quality parameters that are visually assessed in a sample. As many ofthese quality parameters are visually assessed, differences in interpretation can exist,leading to industry frustration over inconsistent interpretation and application ofStandards.The existing Visual Recognition Standards Guide lists a range of definitions andprovides photographic charts of a range of defects for various commodities. This Booklet

is approved for use by a number of industry organisation and companies, including GTA.In the absence of an objective method to assess these quality parameters, the Booklet isundergoing revision to make interpretation of the various defects easier for industry. It ishoped that a revised Booklet will be signed off by the Committee and made available forthe 2011/12 harvest.

3.1.2 Grasshoppers/Locusts Definition All Cereals

The majority of industry agreed that the current definition for Grasshoppers/Locusts isconfusing. Therefore the previous reference to For grasshoppers, six legs, three body
http://www.graintrade.org.au/http://www.graintrade.org.au/http://www.graintrade.org.au/http://www.graintrade.org.au/



parts and two wings or part thereof, constitutes one insect. More than one of the samebody part constitutes greater than one insect has been deleted.For all cereals, the Field Insects Large and Small category for 2011/12 will be defined as:These are insect contaminants of grain that do not cause damage to stored grains. Thereare separate tolerances for Large and Small Insects. They include but are not restricted to:

Large Insects Small Insects

Desiantha Weevil (Desiantha spp) AphidsGrasshoppers, Locusts Minute Mould Beetle (Corticaria spp)Hairy Fungus Beetle (Typhaea stercorea) Mites (Acarina spp.)Ladybirds Stored Grain Insects (dead only)Pea Weevil (Bruchus pisorum) (dead only)Sitona Weevil (Sitona spp)

Wood Bugs

Tolerances apply to either Live or Dead whole Insects for most species, however note forLive Pea Weevil and Live Stored Grain Insects, a nil tolerance applies refer to thedefinition of Stored Grain Insects. For all Insects pieces are included in Other ForeignMaterial or Foreign Material, as applicable. The existing tolerances remain unchanged.

3.1.3 N/A Definition All Cereals

To clarify the intent of the Standards, a definition of Not Applicable - N/A has beenincluded as follows:In these Standards means not applicable. That is, no minimum or maximum toleranceexists. The quality parameter may exist at unlimited levels in the sample.

3.2 Wh eat (Section 2)

In addition to the points outlined in 3.1 above that apply to all cereals, the following changes weremade to wheat Standards only.

3.2.1 For Frost, clarified the definition as per the Visual Recognition Standards Guide, being

Grain damaged as a result of frost during the maturation phase, affected by or duringdrying operations, or by any damage occurring during plant growth due to herbicides.Grains generally have the appearance of full sized kernels with little or no structure on

both dorsal sides of the grain, and are typically grey to blue in colour. The definition doesnot include grain pinched as a result of dry conditions or disease during maturation.

3.2.2 For Field Fungi, remove the reference to mould like substance. This terminologycreated confusion over the 2010/11 harvest as mould currently exists at a nil tolerance.The definition is now Field Fungi refers to individual kernels where the seed coat isgreater than 50 percent discoloured which may or may not be caused by the developmentof fungi during periods of high moisture. The visible discolouration of affected grains can

vary from dark grey, brown to black in colour. Grains that are 50 percent or lessdiscoloured are to be classified as Stained. Grains that are soft and/or emit a mouldyodour are to be classified as Rotted.

3.2.3 Similarly, for Stained, remove the reference to mould and alter to fungal.3.2.4 For Pink Stained, clarify the definition to include Grains that are pink but also contain awhite to grey fungal like discolouration over more than 50% of the seed coat surface areto be classified as White Grain Disorder/Head Scab.

3.2.5 Alter the tolerances for various categories within the Stained/Field Fungi categories tothe following in the table below:

Stained keep existing tolerances, of which there is a maximum Pink Stainedand a maximum of White Grain Disorder and Head Scab

Pink Stained keep current tolerances White Grain Disorder/Head Scab remove both from the Field Fungi category

and create a separate category as part of the total Stained category with a new



tolerance of 1% across all grades. These two parameters are combined into theone category as they are often difficult to distinguish in a sample.

Field Fungi keep as a separate category but alter the tolerance and removeWhite Grain Disorder and Head Scab

Note: in the above table, where a change in tolerance applies, the previous tolerance is indicatedin brackets and the new tolerance to apply is not in brackets

3.2.6 Altered the Varietal Master List. Changes to the Varietal Master List have been made asper deliberations of the Wheat Classification Council. No further changes will occur to the

list for the 2011/12 season A number of varieties have been removed from the Master List because they are

more than 10 years old and have not been delivered for two consecutive seasons.This will mean that if any of these varieties were to be presented for deliveryduring the 2011/12 harvest or any subsequent harvest they will only be receivedas FEED

Classifications of varieties still in production will be reviewed after 10 years. As aresult the Master List now contains information about the classification date andreview date for varieties. This information is incomplete for some varieties and

will be finalised as soon as the information can be sourced from breedingcompanies

A number of new varieties have been added. These include ESTOC, FORREST,JUSTICA CL PLUS, KORD CL PLUS, KUNJIN, LRPB COBRA, LRPB ENVOY,

LRPB IMPALA, PRESTON, REVENUE, WEDIN A number of varieties have had their classifications reviewed and changes are

reflected in the Master List. These include LRPB SPITFIRE, LRPB SCOUT, LRPBBULLET , LRPB LINCOLN

A note that Voluntary down-grades are permitted has been added to thissection of the document, reflecting current industry practice

3.2.7 Altered the definition of Other Non-Objectionable Material. As material in this categorymay or may not be objectionable, it was decided to alter the term to Other ForeignMaterial. This now reflects the nature of this category to include a wide array of foreignmaterial that is not wheat and is otherwise not listed in the Standards.

3.2.8 Delete the grade ANW1 (NSW/VIC) CSG 121.There were previously two main Noodle No.1grades

CSG 120 ANW1 (WA) CSG 121 ANW1 (NSW/VIC)For 2010/11, the differences between these two grades were removed, making the

tolerances for all quality parameters the same for both grades. As there is now no longer arequirement for the two grades the latter, CSG 121 has been deleted and the formeraltered to apply nationally as CSG 120 ANW1.

3.2.9 For weed seeds, several clarifications have been made to all grades:

Bellvine (Ipomoea plebeia) has been added to Type 3a weed seeds as it waspreviously inadvertently omitted

In Type 3C, Note included in this Type are tolerances for seeds or pods hasbeen added as it was previously applied but not stated in the Standards Booklet



In Type 7(a), added Broad Beans (Vicia faba) to all Standards tables as it was notlisted previously

3.2.10 Previous Bin Grade Cascade rules for ASF1 allowed downgraded Soft wheat to be receivedinto the Noodle wheat grade, as outlined below:

ASF1 (SFE) SFT1 (SFE1) / SFT2 (SFE2) / ANW2 /AGP1 / AUW1 / HPS1 / SFW1 / FED1

As Noodle wheat is of significantly different quality than Soft wheat, the committeeagreed to delete the reference to ANW2 and not permit Soft wheat to be accepted as

ANW2. The bin Grade Cascade rules will apply as follows from 2011/12 onwards:

ASF1 (SFE) SFT1 (SFE1) / SFT2 (SFE2) / AGP1 / AUW1 / HPS1 / SFW1 / FED1

3.2.11 In reference to Screenings in ANW2 in a previous season, a submission was received fromindustry to alter the Standards in an effort to segregate as much Noodle wheat as possibleand ensure downgraded Noodle wheat was not lost by being commingled into AGP1stacks. This proposal was subsequently withdrawn as sufficient tonnage of Noodle wheat

was received to meet market requirements. A further submission has been received fromindustry seeking a change to meet the previous intention of segregation of Noodle wheat.The committee agreed with the proposal to increase the screenings content of ANW2

from 5% to 10%, to be applicable from 2011/12 onwards. Note for consistency with otherStandards, this also involved an increase in Unmillable Material above the Screen from0.6% to 1.2%.

3.3 Barley (Section 2)

In addition to the points outlined in 3.1 above that apply to all cereals, the following changes weremade to barley Standards only.

3.3.1 For Field fungi, remove the reference to mould. This terminology created confusionover the 2010/11 harvest as mould currently exists at a nil tolerance. The definition nowrefers to Field Fungi refers to individual kernels affected by the fungus Cladosporiumspp. Cladosporium spp. gives the grain the appearance of black spotting occurring

anywhere on the grain. Coverage greater than 1/8th of the grain surface is considereddefective. The fungus usually occurs during periods of high moisture or high humiditytowards the end of the growing period into harvest.

3.3.2 Clarify the intent of the Standards for Shot & Sprouted. The wording on the StandardsCharts for Feed 1 and Feed 2 barley for these parameters has been altered as follows,noting this is not a change in the tolerances that previously applied:

3. 4 Sorghum (Section 2)In addition to the points outlined in 3.1 above that apply to all cereals, the following changes weremade to sorghum Standards only.

3.4.1 For Field fungi, remove the reference to mould. This terminology is now consistent withother cereal commodities. The definition now refers to Field Fungi refers to individualkernels where the seed coat is greater than 50 percent discoloured caused by thedevelopment of fungi during periods of high moisture. The visible discolouration ofaffected grains can vary from white, to grey to black in colour. Field Fungi can be

identified and is generally differentiated from Stained by being able to be rubbed off.Grains that are soft and/or emit a mouldy odour are to be classified as Rotted.

3.4.2 For Stained, remove the reference to mould. The terminology is now consistent withother commodities. The definition now refers to A grain defect caused by either exposureto wet and damp conditions during growth and maturation phases or a stress related

biochemical reaction, which causes individual grains to become visually discoloured. Thisdiscolouration may be caused by a relatively slow growing fungus that affects theappearance of the grain. It does not refer to the more serious storage moulds (refer HeatDamaged, Bin Burnt, Storage Mould Affected, Musty, Mouldy or Rotted).The definition for Stained includes kernels that display the following:

A distinct light grey, to dark brown to black discolouration on 50% or less of thegrain. The discolouration generally is not able to be rubbed off.

Kernels with greater than 50% of a fungal like discolouration are to be classifiedas Field Fungi.

Grains that exhibit small dots covering less than 5% of the surface area of thekernel (a small proportion) are not to be classified as Stained and are otherwise

whole sound grains.3.4.3 Weed seed clarifications have been made to all grades:

Note included in this Type are tolerances for seeds or pods has been added toType 3c as it was previously applied but not stated in the Standards Booklet

Added Broad Beans (Vicia faba) to all Standards tables in Type 7(a) Weed Seedsas it was not listed previously

3.4.4 Industry agreed to alter the descriptors for sorghum standards, to make reference easier.The following will be adopted for 2011/12:

Old GTA Standard New GTA Standard2011/12

CSG 1, no grade name Sorghum No.1CSG 9, no grade name Sorghum No.1aCSG 2, no grade name Sorghum No.2CSG 3, no grade name Sorghum No.3

3. 5 Triticale (Section 2)In addition to the points outlined in 3.1 above that apply to all cereals, the following changes weremade to triticale Standards only.

3.5.1 Developed a Booklet, in combination with Oats and Cereal Rye3.5.2 For Heat Damaged, include in the Bin Burnt, Mould etc category with a nil tolerance. This

is consistent with other commodities. A tolerance for Heat Damaged is currently notlisted

3.5.3 For consistency with other commodities, for Earth, alter the definition from any size toup to 5mm and the tolerance from nil to 3

3.5.4 For consistency with other commodities, for Sand, alter the tolerance from Nil to 50grains and define Sand as between 0.06mm to 2mm

3.5.5 For Frost, create a definition of Frost Damaged grains generally have the appearance offull sized kernels with little or no structure on the sides of the grain3.5.6 Added a definition for Staining

A distinct dark brown to black discolouration on the germ end that, in severecases, may progress to other parts of the grain such as the crease. These grainsare commonly referred to as black point or black tip. The Staining on thegerm must cover more than 50% of the germ

A light grey to black fungal like discolouration that is usually on the brush end ofthe grain. In some cases it may extend to other areas of the grain. Grains thatexhibit small dots covering less than 5% of the surface area of the kernel (a smallproportion) are not to be classified as Stained and are otherwise whole sound



grains. This discolouration does not significantly affect the appearance of thegrain.

3.5.7 For Cereal Ergot altered the current tolerance of 1 Triticale Ergot per half litre to Nil forall Cereal Ergot. This is consistent with Oats and Cereal Rye

3.5.8 For Ryegrass Ergot, altered the current tolerance of Nil to a maximum length of 2cm, asper wheat

3.5.9 Added a reference screen specification3.5.10 Added a category of Other Foreign Material being Other material not otherwise

specified as having a tolerance in the Standards that has the ability to degrade the qualityof Triticale. It includes, but is not limited to the following:

Fine Material - This refers to material such as dust and soil (



Snail Shell and Stored Grain Insects - This includes pieces of Snail Shell (lessthan half an entire shell), pieces of Stored Grain Insects (not whole) and pieces ofInsects Large and Small.

Other - This includes pieces of Sticks that are smaller than the dimensionsspecified under Objectionable Material, and other non-vegetative material.

3.6.11 Changed all Standards tables in Type 2 Weed Seeds to refer to Branched Broomrape

(Orobanche ramosa) as they all incorrectly listed Common Broomrape3.6.12 Added Broad Beans (Vicia faba) to all Standards tables in Type 7(a) Weed Seeds as it wasnot listed previously

3.7 Cereal Rye (Section 2)

In addition to the points outlined in 3.1 above that apply to all cereals, the following changes weremade to cereal rye Standards only.

3.7.1 Developed a Booklet, in combination with Oats and Triticale3.7.2 Include Dry Green or Sappy in the definition for Damaged Grains, as previously there was

no restriction3.7.3 For consistency with other commodities, for Earth, alter the definition from any size to

up to 5mm and the tolerance from nil to 3

3.7.4 For consistency with other commodities, for Sand, alter the tolerance from Nil to 50grains and define Sand as between 0.06mm to 2mm

3.7.5 For Heat Damaged, removed from a maximum of 2% in Damaged Grains and included inthe Bin Burnt, Mould etc category with a nil tolerance. This is consistent with othercommodities as it is often indistinguishable from Bin Burnt grains with a nil tolerance

3.7.6 Added a definition for Staining

A distinct dark brown to black discolouration on the germ end that, in severecases, may progress to other parts of the grain such as the crease. These grainsare commonly referred to as black point or black tip. The Staining on thegerm must cover more than 50% of the germ

A light grey to black fungal like discolouration that is usually on the brush end ofthe grain. In some cases it may extend to other areas of the grain. Grains thatexhibit small dots covering less than 5% of the surface area of the kernel (a small

proportion) are not to be classified as Stained and are otherwise whole soundgrains. This discolouration does not significantly affect the appearance of thegrain.

3.7.7 Added a reference screen specification3.7.8 Added a category of Other Foreign Material Other material not otherwise specified

as having a tolerance in the Standards that has the ability to degrade the quality of CerealRye. It includes, but is not limited to the following:

Fine Material - This refers to material such as dust and soil (



3.8 Maize (Section 2)

3.8.1 Weed seed clarifications have been made to all grades:

Changed all Standards tables in Type 2 Weed Seeds to refer to BranchedBroomrape (Orobanche ramosa) as they all incorrectly listed CommonBroomrape

Added Broad Beans (Vicia faba) to all Standards tables in Type 7(a) Weed Seedsas it was not listed previously

3.9 Oilseeds (Section 3)

The GTA Standards Committee agreed to adopt fully the Australian Oilseeds FederationStandards for 2011/12.

3.10 Pulses (Section 4)

The Committee decided to adopt fully the Pulse Australia Standards for 2011/12. Themajor changes include:

3.10.1 Further refine wording for clarification:

Defective definitions Screenings reference removed from all Standards Removed references to WA variations & revised the lupin WA standards

reflecting previously applied tolerances

Added Reference screen specifications Added a procedure for sizing and de-hulling

3.10.2 The following changes were made:

Added a 3% tolerance for Blondes in Aldinga red lentils Reduced the tolerance for grasshoppers & locusts in Farmer Dressed Receival

Standards

Revised the Green Lentil standard numbering3.11 Birdseed (Section 6)

The Birdseed Standards as proposed by Queensland Agricultural Merchants wereaccepted in full.

4. Issues Considered but Not Approved

The following issues will not be re-considered by the Standards Committee unless a furthersubmission is received from industry. Industry is free to provide their original submission orfurther information to support their views should they wish for any of these issues to beconsidered by the Standards Committee in developing the 2012/13 or future Standards.

4.1 General

4.1.1 Rejected: Specific Procedures & Detailed Information

The Committee received submissions relating to the interpretation and application ofStandards, including:

The use of only specific instruments for assessing grain quality One method only to be used for assessment of various quality parameters,

including Test Weight and Falling Number



Training of all samplers through a common independent organisation, potentiallyby GTA

Auditing of all receival agents and grain samplers by an independent party on aregular basis, potentially by GTA

Variations to the tolerances applying for each test to be listed in the Standards One industry dispute resolution procedure, including a single independent

arbitrator for quality assessment

Existing material such as Standards Booklets and Competency Standards have beendeveloped by GTA in recent years in response to industry requests. The Board consideredrecent submissions and agreed that further guidance was required to be provided toindustry on the correct interpretation and application of Standards. It was agreed thatcommercial providers of appropriate testing equipment, training and other relatedservices should be encouraged and this was not a role solely for GTA.

The Board agreed to continue to provide tools to assist industry in these matters. A rangeof materials will be developed to complement the existing material, including:

Further guidance on the correct use of testing equipment and Best ManagementPractice in running a receival stand operation. This information will be providedthrough the existing Standards Booklets where applicable.

In addition, the current Code of Conduct will be reviewed to consider inclusion ofa range of activities required to run a receival site further information will bemade available through GTA Member updates in 2011/12.

As a consequence of the above, there will be a review of Section 11 and Section 12of the Standards Problem Identification & Best Practice, to integrate thesechanges in those documents.

Concurrently, a paper on a related topic QA in the industry will be presented tothe Board for consideration the outcome will be made available to industry.

Previously identified research topics, some of which relate to the above topics,will be reviewed. Again, the Board is currently considering how to resource thesereviews.

Greater accessibility to the Standards for industry via provision to an on-linedatabase of the Standards

4.2 Cereal Rye (Section 2)

4.2.1 Rejected: Creation of No.2 and No.3 Grades

Off-grade Cereal Rye is received based on regional quality variations and therefore a nationalstandard is not applicable at this stage for this commodity.

5. Potential Changes for the 2012/13 & Beyond Standards

The following highlights potential changes for adoption in the 2012/13 and beyond Standards orhighlights issues where further information and input from industry is required. Industry isencouraged to provide submissions on any of the following points, or any other issues, at any time

by providing a detailed written response to GTA. GTA will formally seek submissions on theissues below and any other matters of interest early in 2012.

5.1 GeneralA number of potential changes to Standards in general were proposed by the Committee in theMember Updates provided to industry during 2011. Industry provided various responses whichthe Committee considered. In summary these included:



5.1.1 Proposed Change: Weed Seed & Foreign Material

The majority of submissions agreed with the intent of the Committee to simplify theStandards in this area. A number of changes to weed seed Types and tolerances have beenproposed by the Committee. It is proposed to conduct trials over the 2011/12 harvest todetermine the impact of the changes. Upon review of the trial results, the Committee willforward any proposed revised Standards to industry for feedback in early 2012 forpotential implementation in the 2012/13 or 2013/14 season.

As per responses to the weed seed review, industry agreed Standards should be simplifiedin the area of assessment of contaminants. The Committee is reviewing the contaminantscategory in conjunction with the weed seed review.

Further guidance to industry on the proposed changes, seeking industry participation intrials, will be provided to industry in the later part of 2011.

5.1.2 Proposed Review: Reference Method for Screenings

While the majority of industry submissions agreed there is a need to develop

specifications for reference screens to be used in situations such as an official dispute, itwas recognised a significant review of the commercial production and availability of thesescreens and the impact of potential specifications on the marketplace was required. Asresources are currently not available, the Committee will advise industry of the potentialtiming for development of these reference screen specifications.

5.1.3 Proposed Change: Develop Reference Booklets for Other Cereals (Maize)

Industry agreed that the production of further Reference Booklets for the remainder ofthe cereals was useful. The Committee will develop a Booklet for Maize in 2012 or thefollowing year.

5.1.4 Proposed Change: Definition of Stained, Field Fungi and Mould Categories

Given the difficulty in assessing weather damaged grain in 2010/11, a range of industrycomments were received on the above and related quality parameters and seeking a fullreview by the committee. Given that future potential changes may be significant andrequire extensive industry consultation, the Committee will provide a paper to industryprior to the 2011/12 harvest outlining proposed changes to the definition and tolerancesof these quality parameters to aid industry interpretation of Standards and clarify theintent of the tolerances.

5.1.5 Proposed Review: Food Safety Sub-Committee

In recent seasons the Standards committee has received a number of comments fromindustry in submissions relating to food safety issues. These topics include weed seedsand pyrrolizidine alkaloids, mycotoxins and mould, ergot etc. As these are linked to the

existing Standards, it has been decided to form a sub-committee of the existing Standardscommittee to consider these topics and potential impacts on the Standards. The Boardhas approved the formation of this sub-committee and the first meeting is planned forlate 2011.



5. 2 Wheat

5.2.1 Proposed Change 2013/14: Test Wheat increase in all Milling Wheat Grades

The Committee continued to receive a number of submissions on this topic. The committeeagreed to continue to review the topic in each season prior to 2013/14 but supported its priorstance as resolved by the GTA Board, being:

The implementation date of the GTA Board Policy for an increase in test weight inmilling grades of wheat be extended to no later than 2013/2014. Test weight will bereviewed annually with the intention to implement the 76 kg/hl test weight in millinggrades at an earlier date if justified.Note - the committee has reviewed data following each recent harvest to determine theimpact of the proposed change on the industry. On the basis of the data to date, the priordecision to alter the minimum is justified.

Plant breeders (including AGT, Intergrain a nd Longreach) are contacted to determinerealistic timelines for the ava ilability of varieties with a propensity for higher Test

Weight to determine the potential for existing and new varieties to meet this

requirement. This discussion and analysis would involve interactions with the WCC andthe National Variety Tria ls. NVT data w ould need to be analysed upon receipt.Note discussions are continuing.

The Wheat Classification Council be approached to include a Test Weight Standard intheir process of assessing and classifying varieties.Note the WCC responded that this was not supported as all varieties to be assessedmust meet the relevant Standards. Discussions are continuing.

Individual Grades be reviewed with a view to increasing Test Weight in the mostappropriate grades first rather than a blanket all milling grades.Note the committee considered this topic and determined that this proposal wouldpotentially lead to additional segregations and was therefore not supported.

An annual review of this decision is conducted to analyse all relevant data re:availability of varieties, current crop quality, market opportunities / requirements.Note on the basis of the information reviewed to date, the prior decision to alter theminimum is justified.

GTA produce a paper for distribution across Industry to outline the outcomes from theGTA Board decision with regard to changes in Test Weight limits.Note a paper will be produced prior to the 2013/14 season further explaining theproposed change and data reviewed in recent seasons supporting the change.

A proforma for industry submissions be developed that outlines the minimuminformation required in submissions.

Done now available on the GTA website.

5.2.2 Proposed Change 2012/13: Varietal Purity Specifications

For all wheat Standards, it was intended to create a minimum varietal purity requirementof 95%. This would be consistent with other commodities. The tolerance is designed toensure where required, inherent quality characteristics of each grade are maintained. It isintended that the tolerance will apply only in the situation where the Load is Declared asMultiple Varieties of Different Grade Classification Status. However, further industrydiscussion is required to ensure this figure of 95% is appropriate for all variety


13/13

admixtures. In the interim, the existing Varietal Declaration Procedure in the WheatBooklet, has been retained.

5. 3 Oats - Pro pos ed Change s 2012/135.3.1 Propose to create a definition for Field Fungi, as previously there was none, being:

Field Fungi affected grains are those grains that exhibit fungal growth on the grainduring periods of high moisture. Individual kernels have a seed coat that contains a darkdiscolouration due to a fungal substance. The visible discolouration of affected grains can

vary from grey to black in colour. Coverage greater than 1/8th of the entire grain surfacemust be present to be considered as Field Fungi. Less than 1/8th coverage is notconsidered Field Fungi. This proposed definition is similar to other cereal commodities.

5.3.2 Remove the reference to Weather Stained Grains and accommodate this parameter viarevised wording in the Stained category. Weather Stained Grains is a very general termand leads to staining, hence the proposal is to replace this wording with Stained.

5.4 Triticale - Pro posed Changes 2012/13

5.4.1 Propose to create a definition for Field Fungi, as previously there was none, being:Field Fungi affected grains are those grains that exhibit fungal growth on the grainduring periods of high moisture. Individual kernels have a seed coat that contains a darkdiscolouration due to a fungal substance. The visible discolouration of affected grains can



5.5 Cereal Rye - Propos ed Changes 2012/13

5.5.1 Propose to create a definition for Field Fungi, as previously there was none, being:Field Fungi affected grains are those grains that exhibit fungal growth on the grainduring periods of high moisture. Individual kernels have a seed coat that contains a darkdiscolouration due to a fungal substance. The visible discolouration of affected grains can



5.5.3 Propose to separate the various parameters in the current Damaged Grains section.Each quality parameter will be listed as a separate item, with a separate tolerance. This

will ensure consistency with other commodities.

5.5.4 Potential to introduce a Falling Number minimum. While a possible minimum of 200seconds was listed in an industry submission, the Committee was advised that a lowerlevel was generally applied and the 200 second minimum was applied as a regionalsegregation by one sector of industry. Further feedback will be sought in 2012 on theneed for this tolerance in the Standard.
