为明确苄嘧磺隆和苯噻酰草胺在稻田系统中的使用安全性,于2010、2011年在杭州、长沙和南宁进行田间试验,研究苄嘧磺隆·苯噻酰草胺0.42%颗粒剂在水稻中的消解动态和最终残留。结果表明,在稻田土壤、水、糙米、谷壳和水稻植株中添加的苄嘧磺隆和苯噻酰草胺的平均回收率为70.78%~116.06%,相对标准偏差（RSD）为0.91%~10.24%;苄嘧磺隆和苯噻酰草胺的检出限（LOD）均为0.02 mg/L,最小检出量均为4.0×10~（-9） g。在水稻移栽后5~7 d,采用直接撒施法在高剂量（270 kg/hm~2,其中苄嘧磺隆有效成分为64.8 g/hm~2,苯噻酰草胺有效成分为1 069.2 g/hm~2）下施药1次的消解动态试验结果表明：苄嘧磺隆和苯噻酰...

This study was conducted to determine the safety of bensulfuron-methyl and mefenacet in rice ecosystem. A field experiment was carried to reveal residual dynamics and final residue of bensulfuron-methyl.mefenacet 4.2 g/kg granule in rice and paddy system in Hangzhou, Changsha and Nanning of China during 2010 to 2011. The results showed that the average recoveries of bensulfuron-methyl and mefenacet spiked in the paddy soil, paddy water, rice, husk and rice plant at the 3 concentration levels of 0.05, 0.10 and 1.00 mg/kg ranged from 70.78% to 11...
