The water dispersible granule comprises, by weight percentage, prothioconazole, tebuconazole, a dispersing agent, a wetting agent, a chelating agent, a disintegrating agent and a filler. A water dispersible granule comprising prothioconazole and tebuconazole which attains better disintegration and suspension properties in high concentration of hard water is prepared in the present invention by adjusting the type of auxiliaries of the water dispersible granule comprising prothioconazole and tebuconazole, and using proper adjuvant combination. It is particularly suitable for countries and regions of higher water hardness. The water dispersible granule of prothioconazole-tebuconazole of the present invention prolongs the persistent period of the agents, and has a good effect in controlling the crop diseases such as stripe rust, leaf scald and powdery mildew in Gramineae crops, and performs better than the existing water dispersible granule of prothioconazole-tebuconazole.
