摘要

Experiments of insecticide to Chilo suppressalis:40%chlorantraniliprole·thiamethoxam water dispersible granule 10 g/667 m2, 63.1% monosultap·bacillus thuringiensis wettable powder 50 g/667 m2 and 15% acitretin·triazophos emulsifiable concentrates 100 mL/667 m2. The result shows 40%chlorantraniliprole·thiamethoxam water dispersible granule 10 g/667 m2 and 63.1%monosultap·bacil-lus thuringiensis wettable powder 50 g/667 m2 have good control to Chilo suppressalis, their 14 d control effects respectively are 92.61%and 90.46%,and safe for paddy growth, no hurting to other beneficial organisms. beneficial organismsbeneficial organismsbeneficial or-ganisms.%选用40%氯虫苯甲酰胺·噻虫嗪水分散粒剂10 g/667 m2，63.1%杀单·苏云可湿性粉剂50 g/667 m2和15%阿维·三唑磷乳油100 mL/667 m2处理二化螟，进行药效对比试验。试验结果表明：40%氯虫苯甲酰胺·噻虫嗪水分散粒剂10 g/667 m2，63.1%杀单·苏云可湿性粉剂50 g/667 m2对二化螟有较好的防效，两者药后14 d防效分别为92.61%和90.46%，且对水稻生长安全，对其他有益生物未见药害。
