86-01是用两种有机磷剂复配而成的杀虫粉剂。该剂的配方由江苏里下河地区农科所通过复配毒力测定于1986年筛选而得。海安农药厂探明了加工生产合适的稳定剂和填充剂,1988年提供了一定数量的样品。经在扬州市多点试验示范证明,该剂对多种害虫有较好的防治效果。 一、毒力测定 1.共毒系数:参照联合国粮农组织推荐的害虫抗药性测定方法,以二化螟为材料,测定复配剂的共毒系数。试虫以水稻芽苗为食料,饲养室保持恒温28±1℃,光照16小时,黑暗8小时,光强2000勒克斯左右。供测虫体为6龄幼虫,体重50～60毫克。
86-01 is an insecticide formulated with two organophosphorus compounds. The formulation of the drug by the Lixiahe District, Jiangsu Province, through the complex of virulence screening in 1986 derived. Hai’an Pesticide Factory proved the processing and production of suitable stabilizers and fillers, in 1988 provided a certain number of samples. After more demonstration in Yangzhou City demonstration that the agent on a variety of pests have a better control effect. First, the determination of virulence 1. Co-toxicity coefficient: reference to the recommended method of pest resistance recommended by the Food and Agriculture Organization of the United Nations, with the Chilo suppressalis as the material, determination of co-toxicity coefficient of the compound. Test insects to rice sprouts for food, feeding room to maintain a constant temperature 28 ± 1 ℃, light 16 hours, darkness 8 hours, light intensity 2000 lux. Insects for the sixth instar larvae, body weight 50 to 60 mg.
