Abstract

The invention relates to the technical field of pesticides, in particular to a bactericide composition for preventing and treating millet downy mildew. The bactericide composition for preventing and treating millet downy mildew in the invention comprises the following binarily compounded effective components: carvacrol, and phenothrin, benzovindiflupyr or mandipropamid. After the effective components are compounded, the two effective components cooperates with each other, and a remarkable synergistic effect is achieved, so the prevention and treatment effect on millet downy mildew can be improved; and on such a basis, the application dosage of a pesticide can be reduced, pesticide residues can be reduced, and environmental pressure can be reduced. The carvacrol and the phenothrin, the benzovindiflupyr or the mandipropamid are subjected to binary compounding, so the risk of drug resistance can be reduced during use, and the defects of single application of any one of the effective components are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide composition for preventing and treating the disease of millet. Background technique [0002] For farmers who plant millet, millet white disease is a common disease, and its pathogenic bacteria is millet white disease fungus. The pathogenic bacteria of millet white disease mixes oospores in manure and soil or adheres to the surface of seeds to overwinter. Among them, soil-borne bacteria are the main source of overwintering bacteria, which can generally survive in the soil for 2-3 years. In the later stage of the diseased plant, the tissue ruptures, and the oospores overwinter on the soil, diseased debris and manure seeds, completing the infection cycle. Millet white disease shows different symptoms in different stages of millet growth, which seriously affects the survival of millet seedlings and earing of millet, and then affects the yield of millet.
