通过三年室内和田间试验,发现硫环杀对防治水稻害虫具有突出的优点,它与杀螟丹、杀虫双都属于同类新型结构的杀虫剂。硫环杀田间亩用量75克防治水稻二化螟、三化螟其效果与杀虫脒、杀螟丹、杀虫双在一个水平上。根区深层施药可兼治水稻多种害虫,并可提高防治效果。残效期可维持7~14天,田间施药1~2次可控制螟害,它不仅具有良好的内吸和触杀作用,还兼有胃毒和熏蒸作用。硫环杀属神经毒剂,对螟虫具有特殊的中毒症状及毒杀机制,对高等动物属中等毒性,无致癌、致突变作用,也不会引起畸胎的形成。根据硫环杀的理化特性、代谢、转化等残留分析,它积累在环境中或食物链上可能性不大,可以取代有机氯农药,其特殊的毒杀机制在克服害虫抗药性方面,可能作为轮换的一个新品种。它是一个很有希望的杀虫剂。
Through three years’ indoor and field experiments, it has been found that thiocarbic ring has outstanding advantages in preventing and controlling rice pests. It belongs to the same kind of novel insecticide with cartap and insecticidal double. Sulfur ring to kill the amount of acres of field 75 grams of rice prevention and control of rice stem borer, the effect of striped stem borer Chlordimeform, Cartap killing, insecticidal double at a level. Root zone deep application of both rice and pests, and can improve the control effect. Residual validity can be maintained for 7 to 14 days, field application of 1 or 2 times to control pest damage, it not only has a good systemic absorption and contact effects, but also both stomach poisoning and fumigation. Sulfide Central to kill nerve agents, the stem borer has a special poisoning symptoms and poisoning mechanism for the higher animals are moderately toxic, no carcinogenic, mutagenic role, it will not cause teratogenic formation. According to the physical and chemical characteristics of sulfur ring kill, metabolism, transformation and other residue analysis, it is unlikely to accumulate in the environment or the food chain, you can replace the organochlorine pesticides, and its special poisoning mechanism to overcome the pest resistance may be as a rotation A new breed of It is a promising pesticide.
