Abstract
The invention discloses a triflumizole water dispersible granule fungicide. The invention belongs to a fungicides technology in the field of plant protection. Combination of the invention comprises 100-600 portion of crude drug, 180-360 portion of promoter, 250-600 portion of vector which is filler and 10-150 portion of binding agent. After the ingredients are mixed by proportion and evenly stirred, mesh powder is obtained through pulverization; the triflumizole water dispersible granule fungicide is made by evenly mixing the mesh powder and the binding agent and through granulating, parching and screening. The invention overcomes weak points of wettable powder and emulsifiable concentrate of the triflumizole and reduces cost for farmers and pollution of environment. Besides, the invention has the advantages of high contents, fast disintegration, upstanding dispersity, easy storing and good stability as well as high reactivity, good effectiveness and favorable safety when in use.
