Pest Management Solutions for Specialty Crops and Specialty Uses

About the IR-4 Project

The IR-4 Project helps specialty crop growers address pest management concerns so they can produce healthy fruits, vegetables, herbs, and other crops recommended for a healthy diet; as well as flowers, shrubs, and landscape plants that enhance our environment.

The crop protection industry focuses their efforts on major crops, leaving specialty crop growers with fewer tools for effectively managing pests. The IR-4 Project develops data necessary for the registration of safe and effective pest management solutions with the U.S. Environmental Protection Agency. IR-4 also supports the registration of specialty uses on major crops, such as corn, soybeans, and cotton.

This year, The IR-4 Project commemorates 60 years of operation. Since 1963, IR-4 has been a trusted ally of the specialty crop community.

IR-4 has an impactful legacy of increasing pest management options, supporting healthy harvests, and generating economic growth.
