Many organic farmers report a reduction in pest pressure after a number of years of organic production. Our goal in this project was to identify relationships between farm management practices, soil quality, and pest populations on mixed vegetable farms. We sampled extensively in potatoes and winter squash on four organic and four conventional farms throughout New York to characterize crop management practices, pest and beneficial complexes, a variety of soil characteristics, weed species and density, and field border flora and fauna. We also conducted educational programs for organic vegetable growers, and conducted efficacy trials for pest management materials approved for organic production.
