森得保制剂大面积飞防越冬代马尾松毛虫效果研究

马尾松毛虫Dendrolimus punctatus(Walker)是鄂东地区松树的主要虫害,过去防治主要使用化学农药或生物农药+化学农药,对环境污染极大,且有相当大的局限性。而生物防治对养蚕又带来极大的威胁,今年英山使用纯森得保生物药剂进行了大面积越冬代马尾松毛虫防治。笔者通过对几个防区的调查和分析表明:灭虫效果达99%以上,没有造成任何污染,既保护了环境,又解决了防虫与养蚕的矛盾,值得推广应用。

Study on Effect of Dendrolimus punctatus(Walker)Aerial-control by Sendebao Biological Agent in Large Scale to Cross over Winter

Dendrolimus punctatus(Walker)is a main pest to Pinus tree in Hubei eastern region.It was used to use chemical pesticide biological chemical pesticide to control the pest which had big pollution to environment with relative big limitation.However,the biological control brings great thread to silk-worm raising,this year,Sendebao Biological Agent is carried out for Dendrolimus punctatus(Walker)control in large scale.The authors indicate based on survey and analysis in several control areas:the effect for pest killing reach above 99%,which can't cause any pollution,and both protect and solve contradiction of pest control and silk-worm raising,it is good to extend and apply.
