稻纵卷叶螟是水稻主要虫害，特别是二晚稻因其生育期较长，从秧田到收割都会受到为害，传统的农药防治方式已不能有效防治。为进一步探索不同农药防治二晚稻纵卷叶螟的防效、持效性和安全性，重点对不同剂量的速效性、持效性药剂的防效进行试验对比。结果表明，当遇到暴发性稻纵卷叶螟为害的时候，速效性配以持效性长的药剂一起施用，其防治效果会得到明显增强；在正常年份，建议选用药效持续时间长的有机或高效低毒农药。

Cnaphalocrocis medinalis Guenee is a major rice pest, especially the doubled-cropping late rice is always damaged from the seedling to harvest pe-riod for the longer growth season, and traditional pesticides fail to control the pest. To further explore control efficien-cy, duration and security of different chemicals on Cnaphalocrocis medinalis Guenee, readily availability of different doses and duration of chemicals were tested and compared. The results showed that in case of fulminant pest damages, chemicals with different readily avail-ability and those of longer duration can be applied together to enhance the con-trol efficiency. In normal years, organic or high-efficiency low-toxicity pesticide with longer duration can be applied.
