Environmental fate:
Animals:In rats, following oral administration,
14C-disulfoton is rapidly absorbed, metabolised, and the radioactivity excreted in the urine. The main metabolites are disulfoton sulfoxide and sulfone, their corresponding oxygen analogues and diethylthiSoil:In soil, disulfoton is very rapidly degraded. The metabolism is similar to that in animals and plants. It exhibits medium to low mobility in soil.Plant:In plants, disulfoton is very rapidly metabolised. The metabolism is the same as in animals.
WATER SOLUBILITY: 25 mg/l at 20° C.
