摘要
为筛选经济、有效、安全的药剂防治稻纵卷叶螟,对5%丁虫腈乳油等5种杀虫剂对稻纵卷叶螟的田间防效进行评估。结果表明,3.2%阿维菌素乳油药效稳定,保叶、杀虫效果均最好,为理想的推广品种;20%甲维·茚虫威悬浮剂、31%甲维·丙溴磷乳油、10%四氯虫酰胺悬浮剂(9080)的药效虽然不及3.2%阿维菌素乳油,但是对稻纵卷叶螟的防治效果也较好,杀虫效果均在90%左右,且持效期较长,适当加大剂量对稻纵卷叶螟有较好的控制作用。
In order to screen the safe and high efficient pesticides to control Cnaphalocrocis medinalis(Guenee),we evaluated the field controleffect of several insecticides such as 5% flufiprole EC against Cnaphalocrocis medinalis (Guenee).The results showed that 3.2% avermectin EC wasthe ideal popularized variety for its stable effect,the best leaf protection and insecticidal effect.Although the control effects of 20% emamectin·indoxacarb SC,31%emamectin· profenophos EC and 9080 were less than that of 3.2% avermectin EC,they also showed better effect,lasting validityperiod against Cnaphalocrocis medinalis(Guenee) and the control effects were above 90%.
