IPM

Methods of Control

▸Cultural ▸Mechanical

▸Variety Selection▸Biological Control▸Regulatory Control▸Chemical Control

IPMMethods of Control

Cultural

▸Makes the environment unsuitable for pests

•rotating crops•burying crop residues•change planting dates

•draining wet areas•use certified seed

IPMMethods of Control

Mechanical

▸By hand▸cultivation

IPMMethods of Control

Variety Selection

▸Choosing resistant plants

IPMMethods of Control

Biological Control

▸Using living organisms to reduce pest population

•ladybugs•wasps

•Bt corn•many other insects

IPMMethods of Control

Regulatory Control

▸Inspections and quarantines•animals, plants, vehicles

•at national and state borders

IPMMethods of Control

Chemical Control

▸Use of chemicals to optimize control•should be used only after all other types of

controls have been explored
