Pesticide screening test for Cnaphalocrocis medinalis control

摘要: 为筛选出适宜防治水稻稻纵卷叶螟的药剂，进行不同药剂防治稻纵卷叶螟田间对比试验，结果表明：供试药剂对水稻安全；每667 m²施用200 g/L茚虫威·甲维盐悬浮剂30 g和3%甲氨基阿维菌素乳油30 mL对稻纵卷叶螟均有较好的防治效果，药后14 d的杀虫防效分别达83.83%和80.40%。

Abstract: Control efficacy of different pesticides on Cnaphalocrocis medinalis were comparatively studied in field. The results showed that the test pesticides were safety for rice growth, application both of 30 g 200 g/L indoxacarb·Emamectin benzoate SC or 30 mL 3% Emamectin EC per 667 m² could effectively control Cnaphalocrocis medinalis, the control efficacies after 14 d of application were 83.83% and 80.40%, respectively.
