摘要
采用植保无人机与手动喷雾方式分析四唑虫酰胺对水稻稻纵卷叶螟和大螟的防治效果,结果表明:200 g/L四唑虫酰胺SC采用植保无人机飞防与人工喷雾防治效果无显著性差异;200g/L四唑虫酰胺SC对水稻稻纵卷叶螟、大螟防效达95%以上、持效期达20 d以上,一次用药可控制一个世代虫害;200g/L四唑虫酰胺SC与200g/L氯虫苯甲酰胺SC(康宽)防治效果相当,无显著差异;200g/L四唑虫酰胺SC每667m2使用量为10 mL,能达到高效防治稻纵卷叶螟、大螟目的。
Plant protection UAV and manual spray are used to explore the control effect of tetrazolamide(Guoteng)on rice leaf roller and giant borer,and the result shows that there is no significant difference between the control effect of 200 g/L tetrazolamide SC by plant protection UAV and manual spray;The control effect of 200 g/L tetrazolium SC on rice leaf roller and rice borer was over 95%,and the effective period is more than 20 days.The harm of one generation could be controlled by one application;The control effect of 200 g/L tetrazolium SC was similar to that of 200 g/L chloramphetamine SC(kangkuan),and there is no significant difference.200 g/L tetrazolamide sc 667m2 at a dosage of 10 mL can effectively control rice leaf roller and rice borer.
