IPM BACKGROUND
Modern and effective approach based on common sense programs
Focuses on long term prevention of pests
Series of management options
![Page 5: I NTEGRATED P EST M ANAGEMENT (IPM) Kari Showers Mycology M 6:30-9:15](https://reader036.vdocuments.site/reader036/viewer/2022081518/55179b235503463e368b5935/html5/thumbnails/5.jpg)
5 STEPS OF IPM
Scouting pest or problem Identifying the pest or problem Assessing the pest or problem Choosing a management technique and
implementing it Evaluating the results

METHODS OF IPM
Cultural Physical Genetic Biological Chemical Regulation
![Page 7: I NTEGRATED P EST M ANAGEMENT (IPM) Kari Showers Mycology M 6:30-9:15](https://reader036.vdocuments.site/reader036/viewer/2022081518/55179b235503463e368b5935/html5/thumbnails/7.jpg)
ADVANTAGE VS. DISADVANTAGE
Advantage Potential to increase
profit Reduce risk of
harming environment and farm workers
Reduce the amount of pesticide used
Delays disease resistance
Disadvantage Requires higher
degree of management
More labor intensive Can be dependent
on the weather

3 COMMON APPLE DISEASE
Apple Scab Cedar Apple Rust Powdery Mildew

APPLE SCAB
Caused by Venturia inaequalis
Infects wild and cultivated apple trees
Symptoms: Olive-green of brown
spots that look scablike
Leaves become dwarfed
Fruit experience cracking and premature dropping
![Page 10: I NTEGRATED P EST M ANAGEMENT (IPM) Kari Showers Mycology M 6:30-9:15](https://reader036.vdocuments.site/reader036/viewer/2022081518/55179b235503463e368b5935/html5/thumbnails/10.jpg)
IPM FOR APPLE SCAB
Remove fallen leaves Pruning apple trees in winter months Spray fungicide when the bud emerges
Then apply at regular intervals if needed Plant disease resistant trees
Liberty and Gold rush

CEDAR APPLE RUST
Caused by Gymnosporangium juniper-virginianae
Spends part of life on Eastern red cedar and apple
Symptoms Orange spots on
leaves and fruits Disfigure fruit and
cause premature leaf and fruit drop
![Page 12: I NTEGRATED P EST M ANAGEMENT (IPM) Kari Showers Mycology M 6:30-9:15](https://reader036.vdocuments.site/reader036/viewer/2022081518/55179b235503463e368b5935/html5/thumbnails/12.jpg)
CEDAR APPLE RUST IPM
Apply fungicides at pink bud stage
Remove eastern cedar trees nearby
Plant scab resistant trees Liberty

POWDERY MILDEW
Caused by Podosphaera leucotricha
Susceptible varities Jonathan and Rome
Beauty Symptoms
Whitish gray powder Leaves curl upward Fruit have netlike
russet
![Page 14: I NTEGRATED P EST M ANAGEMENT (IPM) Kari Showers Mycology M 6:30-9:15](https://reader036.vdocuments.site/reader036/viewer/2022081518/55179b235503463e368b5935/html5/thumbnails/14.jpg)
POWDERY MILDEW IPM
Start early in growing season
Begin at tight cluster Continue until no
new shoots are produced
Plant scab-resistant varieties that are resistant to PM Gold Rush

SUMMARY
IPM is very important in the agricultural world Can potentially save time and money
The 5 steps involved with IPM are very important
Implementing different methods is very helpful
Knowing the IPM for different diseases allows you to plan ahead for years to come
