Pest Management Calendar

 

This calendar is an ever-expanding database on information about life cycle events for common Missoula County plants, pests, and diseases. Below, you will find information about LEAST-TOXIC treatments (those that have the smallest impact on humans, pests, wildlife and insects, like bees and ladybugs, which benefit the garden) as well as HARD PESTICIDE treatments (those that have greater impact on humans and the environment).

Integrated Pest Management (IPM) strives to optimize plant health by:

  • Managing garden and landscape soils for good drainage and aeration
  • Building soil by adding organic matter and properly timed fertilizers
  • Pruning and irrigating according to the needs of particular plants
  • Knowing the plant's level of susceptibility to pest damage

IPM also means knowing as much about each pest as possible.

  • When is the pest MOST vulnerable, infective, or invasive?
  • When is the pest most vulnerable to least-toxic management strategies?
  • What is the least-toxic management tool that can be used successfully?
