氟蟲雙酰胺及其混配劑防治水稻二化螟藥效試驗

氟蟲雙酰胺及其混配劑防治水稻二化螟藥效試驗(畢業論文8890字)
 摘要：二化螟是水稻的重要害蟲之一，發生面積大，危害嚴重。目前，防治二化螟的藥劑主要以三唑磷為主，而二化螟對三唑磷已經產生一定抗性。為尋找到更好的新型藥劑對二化螟進行有效的防治，對20%氟蟲雙酰胺WDG及其混配劑防治水稻二化螟效果進行了試驗，結果表明，每667m2施用20%氟蟲雙酰胺WDG8-12g對水稻二化螟防效及保苗效果、增產效果均很好，且持效期長，是防治二化螟的理想藥劑。

Chemical Experiment on the control of Chilo suppressalis with flubendiamide
Abstract: Chilo suppressalis is one of the terrible pests of rice. They often break out in a large area and can cause a serious consequence. At present, pharmaceutical to control Chilo suppressalis is mainly dominated by triazophos, however, Chilo suppressalis already has a certain resistance on triazophos.To find better agents to gain an effective control of Chilo suppressalis,we had an experiment to control Chilo suppressalis with flubendiamide WDG which is 20% and the mixture of it. The result showed that 20% of flubendiamide WDG8-12g per 667 square meter can have a good control of Chilo suppressalis and have a good result of protecting seedling and increasing protection.So it turn out that this is the ideal agent for controlling Chilo suppressalis.  
Key words: Flubendiamide; Chilo suppressalis; Control effect; Rice
