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EC 90 g、100 g、110 g与用18%杀虫双AS 200 ml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EC 110 g的防治效果更理想。
In order to effectively control the rice leaf roller, efficacy test was made with 20% Zooxanthellae EC as experimental agent and 18% insecticidal double AS as control agent. The results showed that the control effect of 20% Zooxanthelfenosine EC was better than that of 20% Zooxanthelfenoside EC at 90 g, 100 g, 110 g and 20% insecticidal double AS per 667m 2. Among them, the control effect of 20% zoospirulina EC 110 g per 667m2 was more satisfactory.
