Incorporation and Fate of Granular Soil Insecticides
Three commercially available insecticide application configurations and three techniques of incorporation into the soil were compared in a soil bin using artificial soil. Measurements were made to determine the placement of the granules after incorporation. Average granule incorporation exceeded 99% when the granules were applied in the seed furrow. Field tests evaluated the insecticide residue remaining in the soil profile two months after application using an in-furrow technique. Aldicarb was not detected, and terbufos and carbofuran were detected only near the surface.
