Problems solved by technology

However, the single-agent use of dimethomorph is not only costly, but also has the risk of drug resistance
Although the commercialized mixed preparation of dimethomorph and mancozeb can reduce the risk of drug resistance, the control effect is not satisfactory

Abstract

The present invention relates to a bactericide composition containing dimethomorph and its preparation and application. The said composition is compounded composed of dimethomorph, cymoxanil and / or dimethormorph, cymoxanil, metalaxyl and / or d dimethormorph, phosethyl-Al and mancozeb. Its characteristic is the weight percentage of said effective components is: dimethormorph 1 to 90 percent; cymoxanil 1 to 90 percent; metalaxyl 1 to 90 percent; phosethyl-Al 1 to 90 percent; mancozeb 1 to 90 percent. The said composition can be prepared into missible oil, wettable powder, soluble powder, water emulsion, micro emulsion, water solution, suspending agent, microcapsule, or water dispersible granule. The said composition can be used for preventing and controlling plant diseases caused by peronospora, false peronospora and phytophthora. Indoor tests have shown that the said composition has obvious synergies, and good activity for postponing insecticide resistance of pathogenic bacteria.

Description

technical field [0001] The invention relates to the field of agricultural fungicides. Specifically, it is compounded by dimethomorph, cymoxanil and / or dimethomorph, cymoxanil, metalaxyl and / or dimethomorph, aluminum triethylphosphonate, mancozeb fungicide. technical background [0002] Downy mildew and late blight of melons, tomatoes, grapes, lychees, potatoes and other crops caused by oomycetes such as Peronospora, Pseudomonas and Phytophthora are one of the most serious diseases that threaten agricultural production. At present, the control agents widely used in production include metalaxyl, fosetyl-aluminium, cymoxanil, dimethomorph, and propamocarb. , Oxadixyl, and the mixed preparations of these agents with mancozeb and copper preparations, etc. However, due to the characteristics of short incubation period and fast transmission speed of this type of disease, the control effect of the above-mentioned agents is not satisfactory when the disease is prevalent. In addit...
