Integrated Pest Management (IPM) for Wild Blueberry

Importance of IPM

By using IPM we provide living habitats for soil organisms, pollinators, and wildlife while still producing high-quality wild blueberries.

Integrated pest management aims to prevent outbreaks rather than treat infestation through a combination of cultural, mechanical and chemical techniques. IPM tactics should embody all available management options to reduce or maintain pest populations at a tolerable level without complete eradication of the pest.

The combination of techniques is key.

The continual use of a single chemical can lead to resistance in pest populations creating a more difficult situation to manage. Check out the NRCS Program: Integrated Pest and Pollinator Management

The IPM Approach:

  1. Scout and Monitor for early detection.
  2. Properly identify the plant stage prior to taking action.
    1. Maine Wild Blueberry Phenology Guide
  3. Properly identify the pest prior to taking action.
    1. A pesticide application should target a susceptible life stage.
  4. Develop a response method – specific to the pest and population level.
  5. Record response methods for future reference.
  6. Use predictive models when possible.
  7. Use the economic threshold in deciding when chemical management is necessary.
  8. Use chemical management only when there are no other means of control (mechanical or cultural).

An organism should NOT be classified or treated as a pest until it really is one.
