The fate of fenvalerate (Pydrin insecticide) in the soil environment was examined. The half-lives of fenvalerate under laboratory aerobic or outdoor conditions in sandy loam and silty clay loam soils are approximately 75-80 days. In addition to degradation products resulting from the cleavage of the ester linkage, CONH/sub 2/..sqrt.. and 4-OH-fenvalerate were detected. Further degradation of the soil metabolites was evident by the generation of /sup 14/CO/sub 2/ and unextractable residues. The degradation of fenvalerate in the soil environment was primarily by microbial action. Lettuce, beets, and wheat were planted at 30 days, 120 days, and 1 year after the soil was treated with (/sup 14/C) fenvalerate at a rate equivalent to 2lb/acre. The crops were harvested at maturity and were found to contain low levels of (chlorophenyl-/sup 14/C)-and (phenoxyphenyl-/sup 14/C) fenvalerate equivalent residues (below or 1-3 times the limit of detection). Little downward movement of radioactivity was observed in the soil container. It is concluded that under test conditions fenvalerate nonpersistent in the soil environment. In addition, rotational crops planted at various time intervals after soil treatment contained low, if any, significant residue levels of fenvalerate or its metabolites.
