| Abstract/Contents: | "The mobility and persistence of fenamiphos (Nemacur) and fonofos (Dyfonate), and of the sulfoxide and sulfone metabolites of fenamiphos, were examined over 75 and 83-day periods following application on 13 Nov. 1991 and 27 Jan. 1992, respectively, at recommended rates to a cv. Tifdwarf bermudagrass (Cynodon dactylon X C. transvaalensis) USGA-type green at the Ft. Laudesrdale Research and Education Center. Pesticide and metabolite residues in thatch and soil, and in percolate water collected in lysimeters were analyzed by the Pesticide Laboratory at the Everglades Research and Education Center in Belle Glade, FL, using gas chromatography (GC). Residues of fenamiphos and fonofos were found to largely reside in the thatch layer, whereas the fenamiphos metabolites were found to a much greater degree in the soil. Considerable metabolite was detected in percolate water, especially following the first application of fenamiphos. An average of 17.7% of the applied fenamiphos was found as metabolites in the percolate water following the first application, whereas only 1.1% was found after the second application. Nevertheless, both percentages are high relative to the fenamiphos parent compound or fonofos, for which a maximum of 0.06 and 0.02% of applied, respectively, was obtained in percolate water following any one application. Excessive irrigation appeared to contribute to leaching of fenamiphos metabolites." |
