ENVIRONMENTAL FATE
The half-life of carbosulfan was less than 10 minutes in the dry soil. After 8 days the main residue from the phenyl label was carbofuran (54.5% of the TRR), with 3.5% of 3-hydroxycarbofuran, 2.6% of carbosulfan sulfone, and lesser amounts of phenols or oxidized carbamate metabolites of carbosulfan or carbofuran. The predominant residues from the DBA label after 10 minutes were dibutylamine (38.6% of the TRR), carbosulfan (11.4%), Nformyldibutylamine (6.4%) and N-acetyldibutylamine (1.1%). After 8 days the same compounds were detected, but at very low levels (the rest was unidentified). Degradation was substantially slower with the wet soil treated with DBA-labelled carbosulfan. After 48 hours carbosulfan was still 76.2% of the TRR. Photolytic and hydrolytic degradation were also investigated in water buffered at pH 7 and distilled water with both DBA- and phenyl-labelled [14C]carbosulfan (5 mg/l) and irradiation for up to 8 days with a sun lamp. Apart from specifying that the radiation was above 300 nm, the spectral characteristics of the sun lamp were not reported nor was the kept. The half-life was about 1.4 days in buffered water and 4-8 days in distilled water. Degradation was much more rapid in irradiated samples than in controls, although the identified products were the same. Degradation was mainly to carbofuran and dibutylamine. Other lesser products from the phenyl label were carbosulfan sulfone, the 7-phenol and the 3-keto-7-phenol. From the DBA label the main product was dibutylamine, with lesser amounts of N-formyldibutylamine and N-acetyldibutylamine.
Usage: History Insecticide reported by E. C. Maitlen & N. A. Sladen (Proc. Br. Crop Prot. Conf., 1979, 2, 557). Introduced by FMC Corp. in 1982. Manufacturers FMC; Kuo Ching; Sharda; Sundat; Zhejiang.
Application: Biochemistry Cholinesterase inhibitor; activity is due to in vivo cleavage of the N-S bond, resulting in conversion to carbofuran. Mode of action Systemic insecticide with contact and stomach action. Uses Control of a wide range of soil-dwelling and foliar insect pests. Examples of uses include control of millipedes, springtails, symphylids, wireworms, pygmy mangold beetles, frit flies, white grubs, aphids, caterpillars, flea beetles, Colorado beetles, stem borers, leafhoppers, planthoppers, codling moth, scales and free-living nematodes. The product is used in a wide range of crops, e.g. cotton, sugar beet, potatoes, rice, top fruit, citrus, maize, vegetables, sugar cane and coffee.
