| Abstract/Contents: | Brief description of results from a study where formulations of three insecticides (Isazophos, Isofenphos, Ethoprophos) were applied to a fairway with 0.75 inches of thatch and silt loam soil to trace the downward movement of recoverable residues in turfgrass thatch and underlying soil. "Analysis showed that 2, 5, 15, and 29 days 97% + of recoverable residues from all treatments were found in the thatch. At 57 and 91 days, 90% + of residues were still in the thatch. Mean residues in the first 1.0 inch of soil never exceeded 0.4 ppm. Despite water solubilities of 750, 150, and 20 ppm. for technical ethoprop, isazofos and isofenphos, respectively, immediate posttreatment irrigation and regular rainfall, very little of these insecticides moved into the underlying soil. These results should be of considerable significant in terms of the role of turfgrass thatch in the potential for these materials to leach into groundwater. Thatch is apparently an excellent filter." Includes a table of mean recoverable residues (ppm)a/. |
