New York Urban Farms Sustainable Pest Management Fact Sheet Series

Cornell Cooperative Extension has partnered with dozens of urban farms across New York State to demonstrate and evaluate sustainable pest management strategies. Together with farmers, we found success using control methods that prevent or reduce crop losses through exclusion strategies, crop timing, host resistance, the introduction of beneficial organisms, and more. Regardless of management strategy used, common requirements for success include a knowledge of the pest and disease complex, preventative deployment and commitment to the process. The New York Urban Farms Sustainable Pest Management Fact Sheet Series includes case studies highlighting pest management techniques that New York urban farms have found valuable.
