摘要
以25%氰烯菌酯悬浮剂为供试药剂进行田间小区药效试验。结果表明：25%氰烯菌酯悬浮剂2 000~4 000倍液浸种处理对秧田恶苗病平均防治效果为96.70%~100.00%,对本田恶苗病平均防治效果为97.62%~100.00%,防治效果好,对作物生长安全。推荐用量以3 000~4 000倍液为佳,按种子与药液1.0∶1.2的比例进行浸种。
The results of field effect showed that：the average control effect of 25% JS399-19 soaking by 2 000～4 000 was 96.70%～100.00% on bakanae disease in nursery field,was 97.62%~100.00% on bakanae disease in paddy field,the effect was good,and safe to rice.The recommended dose was 3 000～4 000,proportion of seed and JS399-19 was 1.0∶1.2.
