Development and Biological Activities of Flumorph·Pyraoxystrobin 15% OF

研究了阴离子和非离子表面活性剂复配体系对15%氟吗啉·唑菌酯油悬剂体系的影响,简要叙述了该制剂的特点、配方选择、贮存稳定性、生物活性等实验结果。该配方组成:氟吗啉12.0%,唑菌酯3.0%,NNO1.0%,D4250.5%,500#1.5%,NP-7-磷酸酯2.0%,0201B3.5%,T-201.0%,凹凸棒土0.5%,混合溶剂(甲酯油-邻苯二甲基二丁酯体积比2∶1)补足至100%。室内生物活性试验结果表明:该制剂对黄瓜霜霉病具有极好的防治效果,30mg/L防效可达到95.31%。

The suspensibility to the flumorph· pyraoxystrobin 15% OF in compound System of ionic and nonionic surfactant was studied in this paper. Recommend the results of the storage stability and the characteristic of this formulation and biological activity. This formulation composition was flumorph 12.0%, pyraoxystrobin 3.0%, NNO 1.0%, D425 0.5%, 500# 1.5%, NP-7-phosphate 2.0%, 0201B 3.5%, T-20 1.0%, clay 0.5%, the component solvent （methylation soybean oil-dibutyl phthalate 2：1, by vol） makes up to 100%. The biological activity test result indicated that flumorph＇pyraoxystrobin 15% OF has relatively high effects on cucumber downy midew, the control activity was 95.31% on laboratory at the rate 30 mg/L.
