摘要
20 0 0~ 2 0 0 1年我们在广东省电白县进行了 5 %氯氰菊酯乳油在荔枝和土壤中残留消解规律和最终残留量的研究。结果表明 ,氯氰菊酯在荔枝和土壤中消解较快 ,荔枝上的半衰期为 2 3~ 2 5d ,土壤中的半衰期为6 5d。在使用浓度 1 0 0 0倍、施药 2次的情况下 ,最后一次施药距收获间隔期 1 4d ,荔枝全果中残留量为 0 0 4 1~ 0 0 89,在果肉和土壤中的残量均低于 0 0 0 1mg/kg。
The studies on the final residue and dynamic degradation of cypermethrin 0 05EC in litchi and soil were carried out in Dianbai county Guangdong in 2000 and 2001.And the results have showed that the final residue was 0 041~0 089 mg/kg in litchi fruit (all),and below 0 001 mg/kg in the flesh of fruit and soil,at the GAP level.What's more,the half life of cypermethrin in litchi fruit was 2 3 days (2000) and 2 5days (2001),and 6 5 days in soil.
