根据作物的病、虫或杂草的危害情况,选择两种或两种以上的对口农药合理混合在一起施用,可减少或避免病虫抗性发生,提高防治效果,降低用药成本。 1.不同杀虫剂的混用。不同有机磷杀虫剂,如敌敌畏可与敌百虫、乐果、辛硫磷混用;乐果与甲胺磷、敌百虫与马拉硫磷混配对一些害虫均表现明显的增效作用。此外,有机磷和菊酯类或氨基甲酸酯类混用,如敌百虫、敌敌畏、乐果和辛硫磷,可与呋喃丹、抗蚜威、速灭威、速灭菊酯、甲氰菊酯、溴氰菊酯等混用增效显著。马拉硫磷同对硫磷按6:1的比例混用,对水稻二化螟、黑尾叶蝉有较
Depending on the crop disease, insect or weed damage, the choice of two or more counterparts of pesticides mixed with a reasonable application, can reduce or avoid the occurrence of pest and disease resistance, improve the control effect and reduce the cost of medication. 1. Mix different insecticides. Different organophosphate insecticides, such as dichlorvos can be mixed with trichlorfon, dimethoate, phoxim; dimethoate and methamidophos, trichlorfon and malathion mixed on some pests showed significant synergies. In addition, organophosphorus and pyrethrins or carbamates mixed, such as trichlorfon, dichlorvos, dimethoate and phoxim, and carbofuran, pirimicarb, speed off Granville, tricholomathrin, fenpropathrin Ester, deltamethrin and other mixed synergistic significant. Malathion and parathion mixed by a ratio of 6: 1, the rice stem borer, black-tailed leafhopper more
