20%氟虫双酰胺防治稻纵卷叶螟效果研究(6500字)
摘  要：稻纵卷叶螟（Cnaphalocrocis medinalis）是中国南方稻区三大主要害虫之一。由于不同区域耕作制度、害虫迁飞性等多种因素，导致该害虫大暴发频率增加。目前防治稻纵卷叶螟的传统药剂如甲胺磷、杀虫双等,将很快退出“高效、低毒、低残留”农药市场。为筛选出新的药剂，于2010年6月进行了20%氟虫双酰胺防治水稻第六（4）代稻纵卷叶螟示范试验。实验结果表明：虽然20%氟虫双酰胺WG在残虫防效和防卷叶效果略低于20%氟虫双酰胺SC，但20%氟虫双酰胺整体防治效果还是较常用农药好。

The Effect of Using 20% Flubendiamide to Prevent and Cure Cnaphalocrocis medinalis
Abstract:  Cnaphalocrocis medinalis is one of three main pests in Chinese southern rice region. So many factors such as different farming systems in different zones and migration of pests lead to the increase of frequency of pestoubreak. The traditional medicaments to prevent and cure cnaphalocrocis medinalis such as methamidophos and bisultap will soon retreat from the market of pesticide which emphasizes “efficient、lowmammaliantoxicity、residue” at presnt.To screen the new reagent, a experiment using 20% flubendiamide to prevent and cure cnaphalocrocis medinalis was conducted in june,2010 .The result of the experiment has shown that: the 20% flubendiamide’s effect of prevention and cure is better than pesticide in common use from a whole, though in some aspects such as removing residual pests and preventing crozier, the 20% flubendiamide WG is not so good as the 20 % flubendiamide SC.
