Abstract

ABSTRACT Atechnique was developed for detecting the locations of chlorpyrifos (Lorsban 15G) and fonofos (Dyfonate lOG) granules after incorporation into soil. The technique involved treatment of the insecticide granules with iodine and a thin coating of lead dust. The granules were detected in soil samples with X-ray computed tomography (CAT scanning). Two field experiments were conducted to compare wireworm management in sweet potatoes and distributions of chlorpyrifos and fonofos granules after six different pesticide incorporation procedures. Analyses of variance indicated marked differences between incorporation procedures for dispersions of granules, locations of granules, and numbers of granules detected. Wireworm control with fonofos was effective for all incorporation procedures. For chlorpyrifos, the best wireworm control was with two incorporation procedures which dispersed the chemical to all soil in contact with the growing sweet potatoes.
