Abstract
I studied degradation properties of soil from two southwest Kansas fields in which poor control of western corn rootworm, Diabrotica vergifera vergifera Leconte, occurred after several years of continuous use of fonofos. Bioassays with the red flour beetle, Tribolium castaneum (Herbst), and residue analysis of sterilized and nonsterilized soil from both locations treated with fonofos suggest that enhanced degradation was responsible for rapid breakdown of the toxicant. Implications of this finding for growers and extension personnel concerned with corn rootworm control are discussed.
