OVERVIEW

Why it’s important to me Introduction Steps of IPM Tactics of IPM Advantage vs. Disadvantage Popular Apple Diseases

IMPORTANCE/ WHY I CHOSE THIS TOPIC

Very important to farmers

Grew up on a farm Worked at PSU FREC

IPM BACKGROUND

Modern and effective approach based on common sense programs

Focuses on long term prevention of pests

Series of management options

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

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

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

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

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

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
