摘要
[目的]明确18%四唑虫酰胺SC对二化螟的田间防治效果、最佳使用剂量及其对水稻生长的安全性。[方法]采用叶面喷雾、定期调查的方法试验不同使用剂量四唑虫酰胺对二化螟的田间防效。[结果] 18%四唑虫酰胺SC 30、40 g a.i./hm^2处理的保苗效果为85.98%～92.78%,杀虫效果为88.67%～93.74%,优于对照药剂35%氯虫苯甲酰胺WG30 g a.i./hm^2处理;25 g a.i./hm^2处理的保苗效果为80.56%～84.68%,杀虫效果为86.15%～87.72%,与对照药剂无显著差异。[结论] 18%四唑虫酰胺悬浮剂能够有效防治水稻二化螟,对水稻生长安全。
[Aims] The study aims to confirm the efficacy and optimum dosage of tetraniliprole 18% SC on rice Chilo suppressalis and its safety on rice growth.[Methods] The efficacies of tetraniliprole at different dosages on C. suppressalis were tested by using methods of foliar spraying and regular survey.[Results] The protecting rice seedling and insecticidal efficacies of tetraniliprole 18% SC at 30 and 40 g a.i./ha were 85.98-92.78 and 8&67-93.74%, respectively, which were better than that of the control insecticide chlorantraniliprole 35% WG at 30 g a.i./ha. The protecting rice seedling and insecticidal efficacies of tetraniliprole 18% SC at 25 g a.i./ha were 80.56-84.68 and 86.15-87.72%, respectively, which were not significantly different from the control.[Conclusions] Tetraniliprole 18% SC can effectively control C. suppressalis on rice and is safe on rice growth.
