Insect Pest Management in Organic Seed Production

Organic Agriculture June 08, 2015 Print Friendly and PDF

This is an Organic Seed Resource Guide article.

Pest management in organic farming systems is based on the practice of using fundamental components and natural processes of ecosystems, such as soil organism activities, nutrient cycling, and species distribution and competition, to prevent pest populations from reaching economically-damaging levels. For example, crops are rotated, planting and harvesting dates are carefully planned, and habitats that supply resources for beneficial organisms are provided. Soil fertility and crop nutrients are managed through tillage and cultivation practices, crop rotations, cover crops, and supplemented with manure, composts, crop waste material, and other allowed substances.

In organic systems, the goal is to design the production system so that pests do not find plants, are controlled by natural enemies (biological control), or their damage is kept to a minimum. Vigorous, healthy plants are more able to withstand damage caused by arthropods and disease. Therefore, a “plant positive” (as opposed to “pest negative”) approach of managing the system for beneficial processes and cycles and creating healthy soil and plants, is at the foundation of integrated pest management in organic systems.

For more information on the fundamentals of ecological and organic insect pest management, see eOrganic articles on insect pest management as well as the resources listed below.

Insect Pest Diagnostics

Plant diagnostic clinics at Oregon State University and Washington State University provide services to identify insects and arthropods and their damage. Services are provided to the public, but those interested in having a sample identified are encouraged to first contact their OSU or WSU County Extension office. Call for instructions before submitting specimens. Fees are required.
