Efficacy study of 50% Hexaconazole WDG(water dispersible granules)against rice sheath blight were carried on. The results indicated relativity good control of rice sheath blight. The control efficiency in Hectares with the pharmaceutical 90 g/hm2,120 g/hm2,150 g/hm2 on rice sheath blight was 70.67 % ,72.62% and 74.49% ,respectively.While ,it had good safety.It suggested that the dosage should be 120-150 g/hm2.Sprayiag 50% Hexaconazole WDG (water dispersible granules) twice at seven-clay interval was appropriate.
