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:20%唑磷·硫磷EC每667用90g,100g,110 g与18%杀虫双AS每亩200ml比较,20%唑磷·硫磷EC的防治效果比较好。其中20%唑磷·硫磷EC用110 g/667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% Zooxanthal and Phosphorus EC was better when 20% Zooxanthelfen (EC) EC was used per 667 with 90 g, 100 g and 110 g compared with 200 ml with 18% insecticidal double AS per 667. Among them, 20% of zoospirulina EC with 110 g / 667 control effect is more ideal.
