Description:

OSU Extension shares practical, research-based strategies for using Integrated Pest Management (IPM) to prevent and manage pests while protecting people, property and the environment. We help farmers, gardeners and land managers make informed decisions by combining biological, cultural and chemical tools for long-term pest control.

Oregon Integrated Pest Management Center (OIPMC)

The Oregon IPM Center promotes integrated pest management for Oregon and the Northwest region. Integrated pest management is a strategy that focuses on using creative techniques to battle pests. IPM strategies decrease dependence on pesticides as the main tool for battling insects, weeds and plant diseases. These long-term solutions work in harmony to defend against pests on farms, schools, homes, and anywhere pests can be a problem.
