A company seeks technologies that enhance the duration that herbicides, insecticides, fungicides, and similar products are held at a targeted depth within the top layers of soil. Duration should be between 30 and 60 days. The targeted depth varies with the crop plant, soil type, and pesticide, but is usually between the surface and 3-4" deep. The technology should not be persistent and should not affect the following crop. It must degrade chemically or biologically in the soil.
