Problems solved by technology

In most cases, the compounding effect of pesticides is an additive effect, and there are very few compounds that really have a synergistic effect, especially those with a very obvious synergistic effect and a high synergistic ratio.

Abstract

The invention belongs to the technical field of compound pesticides and particularly relates to antifungal composition comprising fenpyrazamine and difenoconazole. The fenpyrazamine and the difenoconazole are taken as the effective ingredients and account for 1%-80% by weight of the composition, and the weight ratio of the fenpyrazamine to the difenoconazole is 50:1-1:10. The composition can be prepared in one of the forms including an emulsifiable concentrate, wettable powder, a suspension, granules, a microemulsion, an emulsion in water and water dispersible granules. The antifungal composition is used for controlling crop diseases and has the characteristics of broad antifungal spectrum, high efficiency, low toxicity, low residues, obvious synergistic effect, reduction of use cost and the like.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and in particular relates to a bactericidal composition of fenpyrafenone and difenoconazole. Background technique [0002] Spotted defoliation, anthracnose, and scab of fruit trees, powdery mildew and leaf spot on vegetables, fruits, flowers, and cereal crops are common and frequently-occurring diseases, which often cause devastating disasters. In actual use, fenpyrafen has very high bactericidal activity against powdery mildew and gray mold on a variety of plants, but the speed of resistance to existing pathogenic bacteria is very fast when it is controlled alone, and the cost of use is high. shortcoming. As a commonly used broad-spectrum triazole fungicide, difenoconazole has protective and therapeutic effects, but it has defects such as increasing resistance year by year, large dosage, many times of control and easy occurrence of phytotoxicity. [0003] In the actual process of a...
