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 labelling in the 4-trifluoromethoxyphenyl group, metabolites were found which contained only the 4-trifluoromethoxyphenyl ring, partly in hydroxylated form. Plants 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. Soil/Environment 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 accumulation in the soil. In practice-relevant applications in forests, the concentrations of residues found in the soil were very low at all times, and declined below the limit of detection after a few months. Metabolism: In soil, 50% of applied triflumuron labelled in the 2-chlorobenzoyl moiety was degraded to CO2 within 112 days and c. 20% of the radioactivity was bound to the soil. When using triflumuron labelled in the 4-trifluoromethoxyphenyl moiety, the compound was mineralised more slowly, while the percentage of bound residues was markedly increased. Metabolism was mainly induced by microbes, and resulted in metabolites which contained just one of the two rings in each case.
Usage: History Insecticide reported by G. Zoebelein et al. (Int. Congr. Plant Prot., 9th, Annu. Mtg. Am. Phytopathol. Soc., 71st, 1979, Abstract 309) and by I. Hammann & W. Sirrenberg (Pflanzenschutz-Nachr. (Engl. Ed.), 1980, 33, 1). Introduced by Bayer AG. Patents DE 2601780 Manufacturers Bayer CropScience; Sundat.
Application: Mainly stomach and contact action. Inhibit insect chitin synthesis, molt the larvae, not form new skin and then make the body deformity and death. Due to its high efficiency, low toxicity and broad-spectrum, it can be used to control corn, cotton, forest, fruit Coleoptera, Diptera and Lepidoptera pests. 225 g/ha can be used to control cotton bollworm and 37.5 g/ha can be used to control pine moth.
