Interregional Research Project No. 4
Center for Minor Crop Pest Management



Fact Sheet

     The IR-4 Project is a partnership between the USDA (CSREES, ARS) and the land grant university system with its Headquarters based at Rutgers University and Regional Offices at the University of California, Cornell University, University of Florida and Michigan State University. Research laboratories and field research centers are located in twenty-five states with representation in all 50 states and territories. IR-4 conducts field trials and residue analyses under GLP to develop food safety data on minor crops, primarily with reduced risk products and biopesticides. Minor crops are high value crops such as fruits, vegetables, nursery plants and others, but low acreage compared to corn, wheat, soybeans and cotton. Minor crops are worth $40 billion, are produced in all states and make up 40% of the total value of all U.S. crops*. Registrants have had little economic incentive to pursue pest control product registrations on minor crops. IR-4 has worked successfully to fill this gap in pest control regulatory clearances on minor crops.

     As FQPA restricts or eliminates the use of certain pesticides on food crops, the work done by the IR-4 Project becomes critical to maintain the quality and quantity of fruit and vegetable production in the United States.
