The Pesticide Risk Tool (PRT) provides growers and IPM pros with detailed risk estimates for 15 different potential environmental and human-health impacts. For risks to pollinators—such as the honey bee (Apis mellifera), shown here on an apple blossom—the PRT considers different exposure routes and includes three separate risk indices to quantify pollinator risk: One for pollinators in the area sprayed while a crop is in bloom, another for pollinators in the area sprayed while a crop is not in bloom, and a third for pollinators immediately outside of the area sprayed.

A classic example in the United States was the use of the insecticide DDT (dichloro-diphenyl-trichloroethane) in the 1940s to 1970s. The use of DDT was detrimental to the reproduction of bald…
