Hot fogging concentrate containing pyraclostrobin and triazole fungicide

Abstract

The invention discloses a hot fogging concentrate containing pyraclostrobin and triazole fungicide. The hot fogging concentrate is prepared from the following raw materials in percentage by weight: 1-15% of pyraclostrobin, 2-20% of triazole fungicide, 1-15% of surfactant and the balance of solvent, wherein the triazole fungicide is any one of triadimefon, simeconazole, imibenconazole, penconazole, diniconazole and bitertanol. In the hot fogging concentrate disclosed by the invention, the pyraclostrobin with a good inhibition effect on germs at low toxicity is combined with the selected triazole fungicide with a broad fungicide spectrum to serve as the active ingredient, thus the product realizes fast strike, has a better control effect on the powdery mildew and downy mildew of cucumber, the scab and leaf spot of banana and the powdery mildew and anthracnose of rubber tree, and realizes an outstanding effect on controlling germs.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a thermal mist containing pyraclostrobin and triazole fungicides. Background technique [0002] Thermal mist is a newly developed pesticide preparation in recent years. It has the characteristics of no need to add water, high utilization rate, strong adsorption force, high work efficiency, and is not easy to cause phytotoxicity. The use of forest trees such as rubber trees. Existing thermal mist, such as the patent of invention with publication number CN101322490, discloses a broad-spectrum bactericidal difenoconazole thermal mist and its preparation method. The raw materials and composition of the difenoconazole thermal mist are: 1-40% difenoconazole, 5-30% surfactant, 0.1-3% synergist, 0.01-2% stabilizer, and the balance is solvent. The spray has a good effect on powdery mildew, scab, anthracnose, rust, leaf spot and other diseases, but the active ingredient of the spray i...
