The IR-4 Project facilitates the registration of pest management products for specialty crops (fruits,vegetables,herbs,and other ornamentals.) Often, specialty crops have limited options for pest control, so the USDA funded IR-4 Program works with universities, industry, and growers to conduct the research to get the crop registered with the EPA.
The UC Davis IR-4 Field Research Center conducts approximately 30 field trials a year to evaluate chemical residue, crop safety, or efficacy. This year we have pest control residue trials in broccoli, plum, sesame, pomegranate, fig, cherry, peach, sunflower, chia, asparagus, and olive.
