Effects of pesticide 40% Difenoconazole· Prochloraz SC on controlling Rice Sheath Blight were studied. 40%Difenoconazole· Prochloraz SC was used to control rice sheath blight of 150 g/hm2, 225g/hm2, 300 g/hm2 three second times after 10 days. The average controlling effects were 72.7%, 89.3%, 96.1%. The average effect of 300 g/hm2 40%Difenoconazole· Prochloraz SC was significantly higher than that of the common-control chemicals. The average effect of 225 g/hm2 40% Difenoconazole· Prochloraz SC was equle to the common-control chemicals and can be promoted.
