Whether you are a conventional or an organic vegetable producer, an integrated pest management or IPM strategy for the modern farm includes a multi-faceted approach consisting of pest prevention and control strategies that aim at reducing pest populations below threshold levels. Proper pest identification and scouting are critical initial steps that form the basis of a proper IPM practice. Indiscriminate use of conventional or organic insecticides have resulted in many cases of insecticide resistance. Cultural control as well as pest exclusion systems suitable for small and large operations are prevention tactics, while insecticides should always be the last resort. Since many organic insecticides are low-persistence products designed to be environmentally friendly, there are additional benefits to evaluating the synergistic effects of rotations and tank-mixes for controlling insect pests. We encourage producers to do their own on-farm tests to gain experience in using new premix insecticides or rotations according to the insecticide label. Growers should keep good spray records and compare multi-year observations for developing a long-term IPM plan.

Few pointers for vegetable growers:
Sources of organic insecticides: Always check the insecticide label on the manufacturer's website before purchase. Many single or premix insecticides are available from online retailers that include Arbico Organics, Gardens Alive, Seven Springs Farm, Forestry Distributing, Amazon, and many others. Make sure to check the expiration date on the package and product quality before mixing. Consult product labels for primary tank-mixing instructions. Do not store insecticide mixes in spray tank to prevent corrosion. Wash application equipment thoroughly after use to prevent cross-contamination and accidental crop damage due to misapplication. When in doubt, call the manufacturer and/or the retailer for product details.
Use the New Organic Vegetable IPM Toolkit Slide Chart
A revised Organic Vegetable IPM Toolkit is now available for natural and organic farmers. This rectangular slide chart has sustainable IPM recommendations for over 20 major vegetable insect pest species and is a good starting point for beginning or transitioning growers. For a free copy, please email firstname.lastname@example.org, contact a commercial horticulture regional extension agent, or attend a beginning farmer workshop in Alabama. Funding for this IPM toolkit was provided by the USDA SARE, BFRD, and Specialty Crops Block Grant Programs.
