7.3: Integrated Pest Management

Integrated Management: Definition

An ecosystem based approach to managing pests, weeds and diseases

Integrated Management: Focus

Long term control, not necessarily eradication

Helicoverpa Life Cycle: Manage alternative hosts

Adult female, larvae

Helicoverpa Life Cycle: Deep cultivation of pupae

Helicoverpa Life Cycle: Spray NPV virus

Larvae

Helicoverpa Life Cycle: Spray synthetic insecticide or Bt toxin

Small larvae

Helicoverpa Life Cycle: Reduce broad spectrum insecticides

Integrated Management Strategies: Features

• Ongoing control through the growing season

• Some methods have limited time use (eg. Correct crop and lifecycle stage)

• Not use all methods = flexibility

• Monitoring needed

• Specific to species and crop systems

Integrated Management: Process

1. Identify disease

2. Effective control
