Environmental fate:
 Animals:Triflumuron labelled in the 2-chlorobenzoyl moiety was metabolised in rats by hydrolytic cleavage, forming metabolites which contained only the 2-chlorophenyl ring and were partly hydroxylated and conjugated. Correspondingly, in experiments with labellingSoil:Degradation: In laboratory tests, triflumuron was moderately quickly degraded in the soil; degradation in the field was more rapid by a factor of 3-5. Repeated applications over 3 years to soil without vegetation did not result in any accPlant:Following spray application to apples, soya beans and potatoes, triflumuron is only slightly metabolised; metabolites were the same as those formed in animals. For residue analyses, it is sufficient to determine the parent compound in the harvested crops.

Signal Word:CAUTION; Hazard Class:III(Slightly hazardous)
