为探索常规杀虫剂防治稻纵卷叶螟效果下降的替代农药,采用25%毒.唑磷乳油进行了田间药效试验。结果表明,25%毒.唑磷乳油防治稻纵卷叶螟虽然速效性不够理想,但具有持效期长、对2~3龄幼虫防治效果较好的特点,在稻纵卷叶螟偏重发生时,可达到理想的防治效果。未发现25%毒.唑磷乳油对水稻产生毒副作用,因此,是防治稻纵卷叶螟较理想的药剂。 In order to explore alternative insecticides to control the decline of the rice leaf roller, a field efficacy test was conducted using 25% toxic azole-phosphorus emulsifiable concentrate. The results showed that 25% toxic azole and phosphorous emulsifiable concentrate could prevent and cure rice leaf roller, although its quick-acting effect was not ideal, but it had long-lasting effect and good control effect on 2 ~ 3 instar larvae. When, can achieve the desired effect of prevention and treatment. No 25% toxicity was found.Zooxophole EC had toxic and side effects on rice, therefore, it was a better agent for controlling Cnaphalocrocis medinalis.
