氟虫双酰胺及其混配剂防治水稻二化螟药效试验

氟虫双酰胺及其混配剂防治水稻二化螟药效试验(毕业论文8890字)
 摘要：二化螟是水稻的重要害虫之一，发生面积大，危害严重。目前，防治二化螟的药剂主要以三唑磷为主，而二化螟对三唑磷已经产生一定抗性。为寻找到更好的新型药剂对二化螟进行有效的防治，对20%氟虫双酰胺WDG及其混配剂防治水稻二化螟效果进行了试验，结果表明，每667m2施用20%氟虫双酰胺WDG8-12g对水稻二化螟防效及保苗效果、增产效果均很好，且持效期长，是防治二化螟的理想药剂。

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
