摘　　要：采用湿式超微粉碎法,通过对乳化剂、分散剂、增稠剂等助剂进行筛选,制备了22%甲基二磺隆·炔草酯可分散油悬浮剂,研究了该制剂的物理稳定性和化学稳定性条件并进行了田间药效验证。结果表明,当乳化剂EL360与6220S以4∶1的比例复配用量为15%,分散剂ATLOX4916添加量为1.5%,增稠剂OF-102添加量为1.0%时,所制备的制剂各项指标达到最佳。该配方解决了甲基二磺隆的分解问题。田间药效试验表明,22%甲基二磺隆·炔草酯可分散油悬浮剂对杂草的防除效果比单剂甲基二磺隆和炔草酯显著提升。In this paper,mesosulfuron-methyl·clodinafop-propargyl 22%oil suspension(OD)were prepared by wet ultrafine grinding.The emulsifiers,dispersants,thickeners and other additives were screened,and the physical stability and chemical stability conditions were studied.The field efficacy test was carried out for verification.The results showed that in the optimal formula of OD,EL360 and 6220S as emulsifier with the ratio of 4∶1 was 15%,ATLOX 4916 as dispersant was 1.5%,OF-102 as thickener was 1.0%.The optimization of the formula solved the decomposition problem of mesosulfuron-methyl.The field trial results indicated that the control effect of mesosulfuron-methyl·clodinafop-propargyl 22%OD against weeds was significantly higher than that of single mesosulfuron-methyl and clodinafop-propargyl.
