The invention discloses carbendazim wettable powder. The carbendazim wettable powder is prepared by the following raw materials, by mass percent: 36%-42% of carbendazim, 0.5%-1.8% of a wetting agent,7.2%-7.8% of a dispersant, and 12%-32% of a filling material. The beneficial effects of the carbendazim wettable powder and the preparation process thereof are that when the dispersant contained in the wettable powder is prepared, phenol or derivatives of phenol are added and a phenolic hydroxyl group is introduced, which improves the reaction activity of lignin in pulping black liquor and the temperature resistance of the product, ensures that the raw materials are reacted and mixed more comprehensively when the wettable powder is prepared and improves the antifungal performance of the wettable powder. An ultrafine grinding mechanism used in the preparation process of the invention crushes and pulverizes the raw materials by rotating a rotary grinding wheel between a rotary grinding discI and a rotary grinding di
