UC and IR-4 support California's fresh produce
California’s fresh produce is supported by the IR-4 project, which facilitates registration of sustainable pest management technologies for specialty crops.
What Has ANR Done?ANR provides in-kind resources to IR-4. UC Cooperative Extension specialists and farm advisors conduct research to help identify and manage pest problems; they request and help prioritize IR-4 research. Four ANR units conduct IR-4 field trials at several UC sites, including Kearney Agricultural, Desert, Lindcove and West Side research and extension centers. The Western Region IR-4 Center at UC Davis helps manage IR-4 by coordinating IR-4 activities in 13 states, working with key stakeholders, and determining the magnitude of pesticide residues on IR-4 field trial samples.
Low risk pesticides are available to protect California's fresh produceBecause specialty crop pest-management needs are met, California's growers can continue to supply consumers with affordable, safe and diverse fresh produce. Between 1963 and 2012, IR-4 has responded to more than 700 requests from California food crop growers. IR-4 data is used to set allowable pesticide residue levels on fresh produce. Over 13,300 new food-use pesticide registrations were supported by IR-4, which accounts for 50% of EPA’s annual food-use clearances. About 80% of IR-4’s work is on new reduced-risk pesticides suitable for integrated pest management, a process used to solve pest problems while minimizing risks to people and the environment. The increased availability of new reduced-risk pesticides has helped California's fruit and vegetable growers reduce their use of the older, broad-spectrum pesticides by 66% in the past 12 years.
Clientele Testimonial“IR-4 is a proven program with proven success! Without IR-4, specialty crop growers would be left with very few tools to protect their crops and their livelihoods.” (Ray Ratto, Ratto Bros. Farms, Modesto, CA)
“Without it, growers would not have products labeled for specialty crops, and the public would miss out on locally grown fruits, vegetables and ornamental crops.” (Steve Little, The Pictsweet Company)
