Abstract

The invention relates to a bactericide containing prochloraz and ethylicin and a preparation method and application thereof.The bactericide containing prochloraz and ethylicin comprises active ingredients and auxiliary ingredients, and the active ingredients comprise, by weight, 5-99 parts of prochloraz; 5 to 99 parts of ethylicin; the auxiliary component comprises the following raw materials in parts by weight: 16-96 parts of an emulsifier; 50 to 200 parts of a solvent; 2-20 parts of a filler; 8-75 parts of a stabilizer; the stabilizer comprises phenyl salicylate and bamboo vinegar. The preparation method of the bactericide comprises the following steps: S1, weighing the raw materials; s2, pouring prochloraz and ethylicin into a solvent to obtain a mixed solution; s3, adding the remaining raw materials into the mixed solution to obtain a liquid medicine; and S4, uniformly stirring the liquid medicine, and standing and precipitating for 90 minutes to obtain the soluble concentrate. The technical scheme provided by the invention can be used for preventing and treating the citrus moss disease, and has the effect of reducing the adverse effect of photolysis on the sterilization effect of the prochloraz fungicide.

Description

technical field [0001] The application relates to the field of bactericides, in particular to a bactericide containing prochloraz and acetoin and its preparation method and use. Background technique [0002] The moss that grows on citrus trees is a complex of pathogenic parasitic algae and pathogenic bacteria. First, moss affects the photosynthesis and gas exchange of citrus trees, and the chlorophyll content and photosynthetic efficiency of leaves are significantly reduced. When the pathogen infects a large area of ​​citrus fruit, moss has a shading effect on the fruit, which significantly reduces the content of sugar, acid, Vc and protein in the fruit, and affects the intrinsic quality of the fruit. Furthermore, the moss is attached to the surface of the citrus tree by rhizomes or other means, competing with the citrus for mineral nutrients and water, preventing the normal metabolism and growth of the tree. In addition, moss hinders the spraying of pesticides and foliar ...
