25%吡唑·毒氟磷悬浮剂的研制

采用流点法、黏度曲线法确定润湿分散剂种类及用量,并通过筛选增稠剂、防冻剂等,确定25%吡唑·毒氟磷悬浮剂的最佳配方。其最佳配方组成为:5%吡唑醚菌酯、20%毒氟磷、3%7286、1.5%J601、1%1 1 06、0.2%黄原胶、1%硅酸镁铝、4%乙二醇、0.3%卡松、0.2%消泡剂1 860,水补足至1 00%。该制剂对黄瓜炭疽病防治效果良好,各项性能指标符合悬浮剂的相关标准,具有广阔的开发前景。

Development of Pyraclostrobin+Dufulin 25%SC

The type and dosage of dispersants were determined by flowing point and viscosity curve method. Then the optimum formula of pyraclostrobin + dufulin 25% SC was achieved by screening thickeners and antifreezing agents. The formulation had excellent physical and chemical properties, which was composed of pyraclostrobin 5%, dufulin 20%, wetting-dispersant 7286 3%, J601 1.5%, 1106 1%, viscosity regulator xanthan gum 0.2%, magnesium aluminium silicate 1%, ethylene glycol 4%, kathon 0.3%, defoamer 0.2%, and water making up to 100%. Pyraclostrobin + dufulin 25% SC had high effects on cucumber anthracnose.
