Problems solved by technology

In order to save man-hours and procedures, farmers also add agents to prevent and control fungal diseases while preventing and controlling bacterial diseases. harm and other issues
[0003] At present, organic copper fungicides used for the prevention and treatment of crop diseases have been used for a long time, and pathogenic bacteria have developed a certain resistance to them. The control effect of the organic copper fungicides on agricultural diseases is not ideal, and the control spectrum of organic copper is narrow, which limits its use.

Abstract

The invention relates to a compound composition with methanesulphonyl myclobutanil and an organic copper bactericide and a preparation. The compound composition consists of methanesulphonyl myclobutanil and the organic copper bactericide, wherein the organic copper bactericide is selected from any one of cuaminosulfate, oxine-copper, copper nitrohumic acid, mixed amino acid copper, copper resinate, copper citrate, copper succinate, cupric nonyl phenolsulfonate and copper acetate; the weight ratio of the methanesulphonyl myclobutanil to the organic copper bactericide is (10:1)-(1:50). The invention also relates to an agricultural bactericide; the agricultural bactericide contains 0.1-90wt% of the compound composition. The compound composition and the preparation thereof have a remarkable synergetic interaction effect in comparison with single dosage and have the advantages of improving the bactericidal effect, reducing the dosage, reducing the control cost, bringing benefit to delay or resist the bacterial drug resistance and decreasing the environmental pollution and the pesticide residue at the same time.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to a compound composition, in particular to an agricultural fungicide containing mesycloconazole and organic copper fungicides. Background technique [0002] In actual agricultural production, bacterial diseases are accompanied by fungal diseases. In order to save working hours and procedures, farmers also add agents to prevent and control fungal diseases while preventing and controlling bacterial diseases. harm and a series of other issues. [0003] At present, organic copper fungicides used to prevent and control crop diseases have been used for a long time, and pathogenic bacteria have developed a certain resistance to them. The control effect of the organic copper fungicides on agricultural diseases is not ideal, and the control spectrum of organic copper is narrow, which limits its use. . Organocopper fungicides are copper preparations containing carbon (C) eleme...
