15%甲氰菊酯—哒螨酮乳油是化工部农药剂型中心新近研制出的复配杀虫剂,通过对危害李树的山楂叶螨田间药效试验,结果表明15%甲氰菊酯—哒螨酮乳油防治山楂叶螨效果较好,使用浓度2000倍液的防治效果等于对照药剂20%甲氰菊酯乳油、优于15%哒螨酮乳油;使用浓度2500倍液的防治效果略低于对照药剂20%甲氰菊酯乳油、等于15%哒螨酮乳油。因此,推荐田间使用浓度为2000—2500倍
15% Fenpropathrin - pyridaben EC is a compound pesticide newly developed by the Ministry of Chemical Industry Pesticide Formulation Center. Through the field efficacy test of hawthorn leaf mite endangering the plum tree, the results showed that 15% fenpropathrin- Pyridaben cream control hawthorn spider mite better effect of the concentration of 2000 times the control effect is equal to the control agent 20% fenpropathrin EC, better than 15% pyridaben EC; the use of the concentration of 2500 times the control effect is slightly lower 20% of the control agent fenpropathrin EC, equivalent to 15% pyridaben EC. Therefore, the recommended field use concentration of 2000-2500 times
