摘  要:
试验结果表明,拟除虫菊酯农药对水稻害虫具有较好的防治效果,在参试的4种药剂中,以氯氟氰菊酯效果最佳。2.5%氯氟氰菊酯乳油10 mL/667m2对稻螟蛉的防治效果达97.8%,比甲胺磷提高43%以上;15mL/667m2对稻纵卷叶螟的防治效果达95.9%,与甲胺磷相当;25 mL/667m2对二化螟的防治效果达71.2%,比甲胺磷提高23.5%,与打虫灵相当;用40 mL/667m2对三化螟的防治效果达94.1%,比甲胺磷提高48.5%。

摘  要:
The results showed that control efficacy of pyrethroid pesticides to insect pests of rice was good. Cyhalothrin was best in four test pesticides .The efficacy of 2.5% cyhalothrin (10mL/667m2) to Naranga aenescens may reach 97.8% and increase 43% than methamidophos. The efficacy of 2.5% cyhalothrin (15mL/667m2) to Cnaphalocrocis medinalis may reach 95.9% and had almost the same effect as methamidophos. The efficacy of 2.5% cyhalothrin (25mL/667m2) to Chilo suppressalis was 71.2% and increase 23.5% than methamidophos and had almost the same effect as dachongling. The efficacy of 2.5% cyhalothrin (40mL/667m2) to Tryporyza incertulas was 94.1% and increase 48.5% than methamidophos.
