地下害虫是我国重要农林害虫,新中国成立后二十世纪(50-60年代),六六六是防治地下害虫的当家农药。上个世纪70-80年代地下害虫又一次猖獗危害,尤以黄淮海地区为甚,当时六六六残留问题已显现,中国农科院植保所接受取代六六六、研制防治地下害虫新农药的任务后,随即联合有关农药、植保院、所开展工作,对数十种杀虫剂进行了毒力测定、药效试验,其中也包括喹硫磷,初步试验证明其对地下害虫有一定防治效果。但那时因工艺落后,技术水平低,有关农药单位提供的样品,质量低劣,且不稳定,为了按时完成任务,无奈我们当
Underground pests are important pests of agriculture and forestry in our country. After the founding of new China, the 20th century (50-60’s) and 666 were the home-grown pesticides to control underground pests. The underground pests in the 1970s and 1980s were once again rampant hazards, especially in the Huang-Huai-Hai region. At that time, the problem of 666 residues appeared. The Chinese Academy of Agricultural Sciences received a replacement of 666 to develop a new pesticide to control underground pests After the task, the joint work on pesticides, plant protection centers, and do the work carried out on dozens of insecticides were tested for toxicity, efficacy tests, which also includes quetiapine, preliminary tests showed that the underground pests have some control effect . However, due to the backward technology and low technical level, the samples provided by the pesticide units were of poor quality and unstable. In order to complete the tasks on time,
