Abstract
[Objective]The aim was to study drug screening on prevention and control of rice sheath blight. [Method]Using several common reagents in Jiangsu market,the drug was sprayed at a time on peak and the onset stage of rice sheath blight. [Result]Its bacteria ester 40% WP 150 and 225 g / hm2had better control effect on rice sheath blight,and recommended dosage was about 150,225 g / hm2,using at the beginning of rice sheath blight disease,amuse 2-3 times. [Conclusion]Its bacteria ester 40% WP 150 and 225 g / hm2had better control effect on rice sheath blight.
