Abstract

The invention relates to a wettable powder compounded by dimethomorph and polyoxin and a preparation method thereof. The wettable powder is compounded by the following components: 10-50% of dimethomorph and 2-10% of polyoxin (preferably 20-30% of dimethomorph and 2-5% of polyoxin), a dispersing agent, a wetting agent, an adjuvant and a carrier. The two effective ingredients can produce synergistic effect, thus effectively reducing the single dose, enlarging the bactericidal spectrum, lowering the chemical injury, obviously improving the control effect on germs, relieving the drug resistance problem of pathogenic bacteria and lowering the control cost; and the effective ingredients have good control effect on downy mildew, epidemic diseases, leaf spot, gray mold and the like of a pluralityof crops such as fruit trees, vegetables, field crops and the like; and the obtained wettable powder has good environmental compatibility and good popularization prospect.

Description

(1) Technical field [0001] The invention belongs to a new dosage form of a pesticide bactericidal composition, in particular to a wettable powder compounded with dimethomorph and polyoxin and a preparation method thereof. (2) Background technology [0002] Dimethomorph is a cinnamic acid derivative that has strong biological activity against fungi of the Peronaceae family and Phytophthora. The main mode of action is to cause the decomposition of the sporangia wall and cause the death of the bacteria. The drug has systemic properties and can conduct in various parts of the plant, so as to achieve the purpose of comprehensively preventing and controlling plant fungal diseases. Although it has a good control effect in the prevention and control of agricultural diseases, the control cost is high, the safety factor for crops is low, and phytotoxicity is easy to occur. [0003] Polyoxin is a broad-spectrum, high-efficiency, low-toxicity, and safe antibiotic biocidal agent with g...
