The Northwest Center for Alternatives to Pesticides has produced a free, 8 minute video on how Oregon nursery producers are learning to deploy predatory insects in their greenhouses and fields to combat insect pests like white flies, thrips and spider mites.  They explored the new approach with Oregon State University after they saw that pests had become resistant to the insecticides they were using. The surprise was that while it required retraining staff,  it generally didn’t cost any more than using synthetic pesticides. Watch the video here or on NCAP’s YouTube channel.
