杀虫双是根据沙蚕含有的“沙蚕毒素”的化学结构而人工合成的沙蚕毒素类的仿生杀虫剂。对害虫具 有强的触杀和胃毒作用,害虫接触和取食药剂后,表现出迟纯、行动缓慢,失去侵害作物的能力,停止发育,虫体软化、瘫痪直至死亡。杀虫双又有很强的内吸作用,能被作物的根、叶等吸收而传导。颗粒剂具有使用方便、药效长、不受气候条件影响等优点,尤其适合于防治稻螟虫等钻蛀性害虫。还可与除草剂、化肥混合使用,既防虫又除草,江口镇1990年引进5％杀虫双颗粒剂26000公斤防治四代三化螟,示范面积10400亩,使全镇平均白穗率降低到0.087％;1991年推广57500公斤,防治面积23000亩次,有效地控制三化螟的危害,使大发生之年损失甚微。早稻平均白穗率为0.12％,晚稻平均白穗率仅0.07％。
Insecticidal double is based on the Nereis contained “Nereis textiles” chemical structure and artificial Nereis toxin bionic insecticides. Pests have a strong contact and stomach poisoning effect, the pests access to and feeding on the drug, showing a late pure, slow action, loss of ability to infringe on crops, stop development, insect body softening, paralysis until death. Insecticidal double strong internal absorption, can be crop roots, leaves and other absorption and conduction. Granules have the advantages of easy to use, long efficacy, and not affected by climatic conditions, and are especially suitable for controlling bore insects such as rice stem borers. May also be mixed with herbicides and fertilizers, both pest control and weeding, Jiangkou Town in 1990 to introduce 5% insecticidal double granules 26000 kilograms of prevention and control of four generations of Borer, the demonstration area of 10400 acres, the town average white spike rate is reduced to 0.087%; 1991 to promote 57,500 kilograms, prevention and control area of 23,000 acres, the effective control of the harm of Borer, so that the great loss of small years. The average white spike rate of early rice was 0.12% and the average white spike rate of late rice was only 0.07%.
