Resource Guide for Organic Insect and Disease Management, Second Edition
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program

Organic farmers rely primarily on preventive, cultural and integrated methods of pest and disease management. However, there are a number of materials available for use that can complement and support organic management. This guide was developed to provide a useful and scientifically accurate reference for organic farmers and agricultural professionals searching for information on best practices, available materials and perhaps most importantly, the efficacy of materials that are permitted for use in organic systems. Many products available to organic farmers have not been tested extensively, and current research has not been summarized or made widely available to the general producer. A major objective of this guide has been to review recent literature for published trials on material efficacy in order to provide reliable information that can be used by farmers to effectively manage pests. Additionally, a goal was to identify what materials have shown promise but need more research.
Created with SARE support, you can download the Resource Guide for Organic Insect and Disease Management, Second Edition from Northeast Sustainable Agriculture Research and Education (SARE).
