Abstract:

Supernatant from aqueous dispersions of turfgrass thatch and soil from four Ohio golf courses where spring application of isofenphos (Oftanol) failed to control summer-generation scarabaeid larvae, were injected into a buffered nutrient solution of 10 ppm isofenphos. High-pressure liquid chromatography analysis showed that isofenphos disappeared (91 to ≥99%) in ≤3 d, whereas no degradation occurred with samples from an untreated site. Methods described may be useful in elucidating the enhanced degradative potential of certain other pesticides.
