ENVIRONMENTAL FATE

Animals Low residues were found in nearly all ruminant and poultry tissues. Extensive metabolism was observed, with a large number of minor metabolites being produced Plants Limited metabolism in most plant species; minor metabolites indicate a pathway involving hydroxylation or oxidative loss of the tert-butyl group, followed by opening of the heterocyclic ring. Soil/Environment DT50 (25 ) 104 d (flooded conditions, silty clay loam, o.c. 3.8%, pH >6.4), 80 d (upland conditions, sandy loam, o.c. 2.4%, pH 7.0) (J. Pestic. Sci., 11, 605-610 (1986)).
