报道了苄嘧磺隆在水稻上的残留量分析方法。样品经提取、液 液分配、C 18小柱净化 ,添加浓度 0 .0 1～ 2 .0 0mg/kg ,回收率可达到 73.5%～ 96.3%。北京、杭州两地的试验结果表明 :①残留消解半衰期 ,田水为 3.0～ 3.5d ,植株为 6.8～ 8.1d ,土壤为 17.6～ 2 2 .1d。② 30 %威农可湿性粉剂每 666.7m2 有效量 5.0～ 7.5g施用 ,糙米、谷壳、土壤、植株中的残留量≤ 0 .0 3mg/kg。 Reported the bensulfuron methyl residues in rice analysis. The samples were extracted, liquid-liquid partition and C18 column were purified. The concentration of the sample was 0.01 ~ 2.000mg / kg, and the recovery rate could reach 73.5% ~ 96.3%. The test results in Beijing and Hangzhou show that: (1) The half-life of residual digestion is from 3.0 to 3.5 days in field water, from 6.8 to 8.1 days in plants and from 17.6 to 21.2 days in soils. ② 30% Weinon WP per 666.7m2 effective amount of 5.0 ~ 7.5g application, brown rice, chaff, soil, plant residues ≤ 0 3mg / kg.
