红蜘蛛、潜叶蝇、豆野螟是豇豆的主要害虫,由于虫、螨混合发生,而常用的化学农药中还没有一个能兼治虫、螨的高效农药品种,所以豇豆田害虫的防治难度较大,经常暴发成灾。寻求广谱、高效、低毒、低残留农药防治豇豆主要害虫已成为广大科研人员和菜农的迫切需求。为此,受浙江省植保总站的委托,杭州蔬菜研究所在1998年7月进行了阿维菌素防治豇豆害虫的药效试验,现将结果报道如下:
Spider mites, leaf miner and soybean borer are the main pests of cowpea. Due to the mixed occurrence of insects and mites, none of the commonly used chemical pesticides can effectively kill insects and mites. Therefore, it is more difficult to control the pests of cowpea Large, often outbreaks disaster. Seeking broad-spectrum, high efficiency, low toxicity, low residual pesticides to control the main pests of cowpea has become the urgent need of the majority of researchers and vegetable farmers. To this end, commissioned by the Zhejiang Provincial Plant Protection Station, Hangzhou Institute of Vegetables in July 1998 conducted avermectin efficacy test of cowpea pests, the results are reported as follows:
