摘要
通过用25%苏脲Ⅰ号、2.5%氰苯菊脂两种农药单剂以及四种混剂对马尾松毛虫(Dendrolimus punctatus Walke)进行室内毒力测定,筛选出一种最佳混剂用于林间防治马尾松毛虫。试验表明:该混剂防效好、速效且副作用小、推荐使用量为500g/hm2。
indoor toxicity test of 25% chlorbenzuron, 2. 5% deltamethrin, and four mixtures of the two fungicides against Dendrolimus punctatus Walke were carried out, based on which an optimal fungicide mixture was screened out. Result of the field experiment showed that the selected fungicide mixture had great control effect and least side effect, with recommended dose of 500g/hm^2.
