20唑磷·硫磷EC防治稻纵卷叶螟药效试验初报

摘要

In the paper, we studied the control effect of 20% EC to prevent rice leaf folder. The results showed that 20% EC dose of 90g, 100g and 110g/667m2 has a better effect than 18% AS dose. Therefore, the 20% EC dose has a good effect on preventing rice leaf folder in production.%为了有效防治稻纵卷叶螟，以20%唑磷·硫磷EC为实验药剂，18%杀虫双AS为对照药剂进行药效实验。结果表明：每667m2用20%唑磷·硫磷EC90g、100g、110g与用18%杀虫双AS200ml比较，20%唑磷·硫磷EC的防治效果比较好。其中以每667m2用20%唑磷·硫磷EC110 g的防治效果更理想。
