When farmers spray pesticides, what happens to beneficial organismsthose insects and diseases that help suppress noxious insects, diseases, or weeds?

IPM researchers recently tested 65 commercial pesticides for mortality against five commonly available beneficial insects. The results could be indexed for use in evaluating the overall environmental impact of pesticides.
