Abstract
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.
