Kresoxim-methyl and pyrimethanil compound fungicide composite fumigant and application of fumigant

Abstract

The invention discloses a kresoxim-methyl and pyrimethanil compound fungicide composite fumigant and an application of the fumigant. The kresoxim-methyl and pyrimethanil compound fungicide composite fumigant is characterized by comprising pyrimethanil and kresoxim-methyl, wherein the weight ratio of pyrimethanil to kresoxim-methyl is (8 to 1)-(1 to 5). According to the optimization scheme, kresoxim-methyl and pyrimethanil account for 0.1-60wt% of the fumigant in total. By virtue of the kresoxim-methyl and pyrimethanil compound fungicide composite fumigant, the same effect can be achieved by only using 1 / 2-2 / 3 of active ingredients of other preparations of the same pesticide; the pesticide is saved; the fumigant is high in effect, low in residues and safe to use; the most direct beneficial effect on the agricultural production is that the application cost per mu is reduced and the excellent prevention and treatment effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a kresoxim-methyl and pyrimethanil compound fungicide composition smoke, and the kresoxim-methyl and pyrimethanil compound fungicide composition smoke is used to treat or The application of preventative control of plant diseases caused by specific pathogenic fungi present or likely to occur on specific plants. Background technique [0002] Botrytis fungus is a kind of plant pathogenic fungus distributed worldwide, there are more than 20 species, most of which can cause gray mold of plants, among which Botrytis cinerea is the most widely distributed and has the most serious impact . When gray mold is infested, white flocculent mycelium usually forms on the surface of the diseased part, and then the mycelium turns gray during the process of forming conidia, hence the name gray mold. The host range of Botrytis cinerea is extremely wide, and it can infect more than 2...

Problems solved by technology

[0005] Since the 1960s and 1970s, a variety of high-efficiency fungicides have been successfully used in the control of gray mold and powdery mildew. Although chemical pesticides can effectively control gray mold and powdery mildew, plant pathogenic fungi are easily Drug resistance occurs, so people need to continuously research and launch new pesticide compounds, but the research and development of new pesticide compounds is a process of large investment, time-consuming, and low success rate. It has synergistic effects and delays the occurrence of resistance, and has the advantages of short development cycle, low development cost and obvious economic benefits

Since most of the protected areas provide melons, fruits and vegetables that are out of season and have high economic value, consumers have higher requirements for product safety, and pesticides and smoke are the main dosage forms used in protected areas. However, what are the specifics? Whether a pesticide is suitable for making a smoke agent, and what is the technical effect of making a smoke agent compared with other formulations of the pesticide, these issues require specific experiments and research
