为明确36%氰虫.毒死蜱SE防治稻纵卷叶螟的效果及对稻飞虱的兼治作用,确定适于宜兴市生产条件下的最佳用量及施药技术,进行了36%氰虫.毒死蜱SE大区药效试验,结果表明:36%氰虫.毒死蜱SE对防治稻纵卷叶螟效果明显,对稻飞虱有一定的兼治作用,在稻纵卷叶螟1、2龄幼虫高峰期和稻飞虱卵孵高峰期每667m2用36%氰虫.毒死蜱SE100～120mL,对水50kg均匀喷雾,对稻纵卷叶螟的杀虫和保叶效果都在95%以上,对稻飞虱的防效也达80%左右,且对水稻生长安全。
In order to clarify the effect of chlorpyrifos SE on controlling rice leaf roller and its effect on the occurrence of rice planthoppers, the best dosage and application technology for 36% cyanobacteria were determined. Chlorpyrifos SE area efficacy test results showed that: 36% Cyanobacteria Chlorpyrifos SE on the prevention and control of rice leaf roller obvious effect on planthopper have some of the role in the control, the first and second instar larvae of rice leaf roller And 36% of Cyperus perenne per 667m2 in the peak of the hatching period of the planthopper and insecticidal insecticide, SE100 ~ 120mL of chlorpyrifos and even spray of 50kg of water, the insecticidal and leaf-holding effects on the rice leafroller are above 95% The control effect of lice is also about 80%, and the growth of rice is safe.
