Abstract

The invention relates to the technical field of a pesticide bactericide preparation, in particular to a combination for preventing and curing downy mildew of fruits and vegetables and an aqueous emulsion thereof and a processing preparation method of the aqueous emulsion. The preparation method helps recompose a triazole bactericide with propamocarb hydrochloride, takes the preparation mode of the aqueous emulsion, and optimizes and adjusts the preparation method of the aqueous emulsion, thus improving the original preparation technology, better preventing and curing downy mildew of fruits and vegetables such as cucumbers, grapes and the like, improving the preventing and curing effect and decreasing usage amount of drugs and drug application times.

Description

technical field [0001] The invention relates to the technical field of pesticide fungicide preparations, in particular to a composition for preventing and treating fruit and vegetable downy mildew, an emulsion in water thereof, and a process for preparing the emulsion in water. Background technique [0002] Triazole fungicides are broad-spectrum, safe and efficient systemic fungicides, are sterol demethylation inhibitors, have a strong inhibitory effect on the spore formation of plant pathogenic bacteria, and have protective and therapeutic effects. Basidiomycetes and including Alternaria, Ascodiospora, Cercospora, Neptonia, Ballacne, Phoma, Septoria, Septoria, and Black Star in It has long-lasting protective and therapeutic effects on domestic half-knowledge diseases, powdery mildew family, rust fungus and certain kinds of pathogenic bacteria, and its representative varieties include difenoconazole, flusilazole, propiconazole, prochloraz, etc. [0003] Propamocarb hydrochl...
