ENVIRONMENTAL FATE
Animals The major metabolites arise from demethylation and demethoxylation. Plants In plants, metabolism involves demethylation and demethoxylation. Soil/Environment Microbial degradation is the primary factor in disappearance from soil. Half-life under field conditions is c. 2-5 mo (F. Kempson-Jones & R. J. Hance, Pestic. Sci., 1979, 10, 449). In soil, DT50 38-67 d. Soil adsorption Koc 500-600.
