摘要
报道了霸螨灵在苹果上残留动态的研究情况。霸螨灵在苹果果实中的原始沉积量 1995年和 1996年分别为 0 .4 70和 0 .761mg/kg,消解半衰期分别为 2 .5和 3.5d。两年试验结果消解趋势基本一致。按推荐剂量 2 0 0 0倍液和高剂量 10 0 0倍液分 2次和 3次施药 ,14 d后测定 ,霸螨灵在苹果中的残留量分别为 0 .0 98m g/kg和 0 .132 m g/kg,不超过 FAO/W HO关于霸螨灵在苹果中残留限量 1m g/kg的规定 。
The study on dynamics of Bamanling residual in apples revealed that in 1995 and 1996 the primal accumulation of Bamanling were 0.470 and 0.761 mg/kg and its half life degradation period were 2.5 and 3.5 days respectively, showing a similar dynamic trend. Two treatments with different application rates and application times were designed (twice application of recommended dosage 2 000∶1 and three times application of higher dosage 1 000∶1). 14 days after the applications, the residual of Bamanling in the apples were 0.098 mg/kg and 0.132 mg/kg, both being well below the 1 mg/kg limit specified by FAO/WHO and, therefore, safe to humans.
