摘　　要：介绍了50%吡蚜·噻嗪酮水分散粒剂的制备方法,简述了该制剂的特点、配方筛选、质量技术标准和贮藏稳定性。实验结果表明,该产品分散性好,悬浮率75%以上,热贮合格,14 d分解率很小,各项指标符合水分散粒剂的要求。田间试验效果表明,该药剂防治水稻稻飞虱药后1 d,7 d,16 d防效分别为67.88%,94.68%,96.85%,明显高于吡蚜酮和噻嗪酮单剂的药效,是值得开发和推广的新型防治水稻稻飞虱的复配产品。The preparation method of pymetrozine ＋ buprofezin 50% WG was introduced.The characteristics,formulation selection,technical standards and storage stability of the agent were also described.The results showed that the product was well dispersed with the suspension rate above 75%,heat storage stability qualified and a low 14 day’s decomposition rate.All specifications were in line with the requirements of water dispersible granule.The field test results showed that the efficacies controlling rice planthoppers after 1,7,16 days were 67.88%,94.68%,96.85%,significantly higher than the efficacy of single pymetrozine or buprofezin.It is worth developing and promoting as a new mixture product againt rice planthopper.
