The disappearance kinetics of the carbamate insecticide, carbosulfan, applied at 2 kg AI ha?1 (‘Marshal’ 250 g litre?1 EC) in peaches was studied. Degradation took place in two consecutive stages (0–28 and 28–57 days), with half-lives of 7.4 and 17.5 days, respectively. The residues obtained 57 days after treatment did not exceed 0.2 mg kg?1. When treatments were carried out 30, 21 and 14 days before the probable date of harvest (date of fruit maturation) with two doses (1.0 and 2.0 g formulated product litre?1) and two volumes applied (750 and 1500 litre ha?1), the residual levels detected were between 0.122 mg kg?1 (30 days before harvest) and 0.4 mg kg?1 (14 days before harvest). The major metabolite, carbofuran, was never detected above its determination limit of 0.004 mg kg?1 throughout the whole study. 相似文献
