Abstract

The invention discloses a fungicide, in particular to a fungicide of bismerthlazol water dispersible granule, which can be used to control rice bacterial blight, rice bacterial leaf streak, tomato bacterial wilt and soft rot of Chinese cabbage. The invention is characterized in that the component contents are (in mass percentage): 200 to 800 bismerthlazol, 20 to 40 wetting agent, 20 to 40 dispersing agent, 20 to 80 disintegrating agent, 10 to 100 binder, 15 to 100 stabilizer and balance of 1000 filler; the mesh powder is obtained after the components are mixed in proportion, stirred evenly andcrushed; the mesh powder and adhesion agents are mixed evenly; then the bismerthlazol water dispersible granule is obtained after granulating, drying and sieving. The invention overcomes the defectsof bismerthlazol wettable powder, reduces consumption cost for peasants and pollution to environment, and has the advantages of high content, rapid disintegration, good dispersibility, favorableness to storage transportation and stability, high activity, good efficiency and safety.

Description

technical field [0001] The invention relates to an agricultural fungicide, in particular to a fungicide for euconazole water-dispersible granules and a preparation method thereof. Background technique [0002] At present, the single dose of the original powder of eucumazole on the market is generally made into a low-content wettable powder for use. Moreover, the wettable powder single agent is seriously polluted by dust in the process of preparation and use, which is very harmful to people and the environment. Convenience, disadvantages such as difficult packaging and high cost of use. Invention content: [0003] In order to overcome the disadvantages of high cost, large pollution, and inconvenient storage and transportation of the prior art, the purpose of the present invention is to improve a low-cost, easy-to-package, convenient storage and transportation, no harm to human health and no pollution to the environment, and improve the effectiveness of drugs. The utilizat...
