Despite almost a half-century of IPM research and Extension efforts, pesticide usage continues to rise. Scientists and policy-makers have criticized IPM for a continued dependency on chemical solutions. They argue that long-term solutions will only be found by restructuring the crop system to incorporate preventative ecological measures that keep organisms from reaching pest status. Extension and IPM risk losing credibility on environmental issues concerning pesticides and risk losing funding to organizations that are willing to develop ecologically based pest management solutions. Perimeter trap cropping is presented as one example of an ecologically based solution.
