50烯啶虫胺防治稻飞虱田间药效试验

摘要

In the paper, we studied the control effect of 50% Nitenpyram to prevent rice hopper. The results showed that the Nitenpyram dose of 7.5 or 10 g/667m2 has a better effect than the Nitenpyram dose of 5 g/667m2. Therefore, the Nitenpyram dose of 7.5 or 10 g/667m2 has a good effect on preventing rice hopper in production.%50%烯啶虫胺WP防治稻飞虱田间药效试验表明，其剂量7.5、10g/667m2，药后1、3、7、14d调查，防效为24.17%～96.81%，高于用量5g/667m2的防效，与对照10%吡虫啉WP30g/667m2防效相当。生产上推荐以50%烯啶虫胺7.5、10g/667m2防治稻飞虱为宜。
