一、前言杀虫单系砂蚕毒素衍生物中首先开发的一种主要农药产品,对水稻害虫、菜青虫等具有较高的防效,是我国更新换代品种之一。其杀虫谱广、药效高、中等毒性、残效期长,虽大量用于水稻害虫的防治,但对其它作物害虫防治报道较少,尚待研究开发。自1982年以来,在中国农科院植保所药效网的协助卞,我们对稻虫进行了试验示范,肯定了药效,鉴于大豆害虫对大豆危害的严重性,1983、1984、1985年连续三年,用更新药剂对大豆全生育期主要害虫的防治进行了统一规划、综合试验示范,取得了较好的结果。我们认为,杀虫单可作为大豆害虫综合防治中的一个优良的农药品种加以推广应用。现将几年的研究结果分别简报如下,供参考。
I. Introduction Insecticidal monasteries sericin toxin derivatives first developed a major pesticide products on rice pests, Pieris rapae has a higher control effect, is one of China’s replacement varieties. Its insecticidal spectrum broad, high efficacy, moderate toxicity, long residual period, although a large number for the prevention and control of rice pests, but less reported on pest control of other crops, yet to be developed. Since 1982, assisted by the Chinese Academy of Agricultural Sciences’ plant protection network, we tested the rice pests and confirmed their efficacy. In view of the seriousness of the soybean pests to soybean, the success of 1983, 1984 and 1985 In the past three years, the new pesticides were used to plan the prevention and control of the major pests in the whole growth period of soybean, and the comprehensive experiments and demonstrations have achieved good results. In our opinion, insecticidal single can be used as an excellent pesticide variety in the comprehensive control of soybean pests. Now several years of research results are summarized below, for reference.
