Residual Dynamics of Carbosulfan in Chinese Chives and Soils

In order to make up the standards for safe use of carbosulfan on Chinese chives, a farmland experiment was conducted to study the residual dynamics of carbosulfan in Chinese chives and soil at application of doses of 750～1 500 mL·hm-2 with carbosulfan 20%EC, respectively. The results showed that carbosulfan dissipated rapidly from Chinese chives. Its half-life in Chinese chives was 1.5 days. The Chinese chives was sprayed three times with carbosulfan 20%EC using the doses of 1 500 mL·hm-2, it was found that the final residues were 0.026 mg·kg-1 in Chinese chives and ND in soil at 14 days after last application, respectively.
