杀灭菊酯和氧化乐果均为杭州农药厂大吨位产品,杀虫性能各具千秋。为了提高杀螨效果,降低毒性和成本,增加稳定性,延缓抗性,我们将上述两种农药进行了合理复配。复配后20％菊氧乳油(菊氧混剂),经1985—1986年试验和测定表明稳定性好,成本大大低于杀灭菊酯,属中等毒性农药。田间药效试验证明实用1000—1500倍可有效防治国槐尺蠖、高粱穗部棉蛉虫、斜纹夜蛾、棉蚜及柑桔、棉花、苹果等作物红蜘蛛;对苹果绣绒菊蚜、蔬菜蚜虫、菜青虫、潜叶蝇、麦蚜用2000—3000倍防效均佳。
Both pyrethrin and omethoate are large tonnage products in Hangzhou Pesticide Factory, with insecticidal properties of different ages. In order to improve the acaricidal effect, reduce the toxicity and cost, increase the stability and delay the resistance, we have carried on the rational compounding of the two pesticides. After compound with 20% of the chrysanthemum oil (chrysanthemum mixture), after 1985-1986 test and determination showed good stability, the cost is much lower than fenvalerate, is a moderate toxicity of pesticides. The field efficacy test proved that practical 1000-1500 times can effectively prevent and cure Sophora japonica, sorghum cotton spike, spodoptera, cotton aphid and citrus, cotton, apple and other crops spider mite; Aphids, Pieris rapae, leaf miner, wheat aphid with 2000-3000 times control effect are good.
