A three year project by the Cornell Vegetable Program researched and promoted natural pest management in greenhouse and high tunnel vegetables via 23 on-farm trials, 4 on-farm workshops, 7 formal winter meetings, 20 articles and 1 webinar. These efforts lead the project to exceed the performance target of 15 growers adopting biological control of pests and diseases in greenhouse/high tunnels, with 20 implementing. Trial data and grower input indicated that while difficult to quantify economically in true field settings, natural pest management can be the difference between a crop and a failure and for many organic growers is their only option.
Of the 80 farmers who attend demonstration farms and educational meetings as part of this project, 15 will adopt biological control of pests and diseases in greenhouse/high tunnel vegetable production within 3 years. These controls could include predatory insects, resistant varieties and microbial fungicides.
