摘要
本文报道了5种杀虫剂防治蔗螟的效果。试验中Regent(锐劲特)用量低且防效最佳,剂量ai50～150g/hm2的防效为62.25%～84.86%。实验中还发现常用药剂呋喃丹的防效明显下降。本文还就引起常用药剂下降的原因进行了分析,提出应加快氟虫腈在甘蔗上的推广力度。

The effect of Regent 0.3G with application rate of 50-150 g/hm^2 in active ingredient is 62.25%-84.86%, and is the best in five insecticides. The efficacy of Furadan reduced considerably.
