Sterilization composition containing zoxamide and isofetamid and application thereof

Abstract

The invention relates to a sterilization composition containing zoxamide and isofetamid and application thereof, and belongs to the technical field of pesticide. The sterilization composition is prepared from the following active ingredients of zoxamide and isofetamid according to the weight ratio of 1:80-80:1; the weight percentage of the zoxamide and isofetamid in the sterilization composition is 10 to 80 percent. The sterilization composition is assisted by auxiliary agents to be prepared into any one dosage form suitable for agricultural production and application; the preferable dosage form can be wettable powder, suspensions, microemulsions, aqueous emulsion and water dispersion particles. Through the reasonable compounding of zoxamide and isofetamid, the obvious synergistic interaction effect can be achieved on crop cucumber downy mildew and cucumber gray mold in a certain range, so that the pesticide consumption is reduced; the prevention and treatment cost is reduced; the environment pollution is reduced.

Description

technical field [0001] The invention relates to a bactericidal composition containing benzamid and iprothiazil and an application thereof, belonging to the technical field of pesticides. Background technique [0002] Benhexamid is a highly effective protective amide fungicide with long-lasting effect and good resistance to rain erosion. Its unique mechanism of action is through binding tubulin β-subunit and destroying microtubule cytoskeleton To inhibit nuclear division, benzamid does not affect the swimming, cyst formation or germination of zoospores. Along with the first cycle of sclerotin division, the elongation of the germ tube is inhibited, thereby preventing the pathogen from penetrating the host plant, It is mainly used to prevent downy mildew and blight, and is also effective against solanaceous powdery mildew and gray mold. [0003] Isoprofen, English common name: Isofetamid, CAS registration number is 875915-78-9, chemical name: N-[1,1-dimethyl-2-(4-isopropoxy-o-...

AI Technical Summary

Problems solved by technology

In most cases, the compounding effect of fungicides is an additive effect, and there are very few compounds that really have a synergistic effect, especially those with a very obvious synergistic effect and a high synergistic ratio. After retrieval, the applicant found that there is currently no literature report on the mixing of benzamid and iprothicarb to prevent and control gray mold and downy mildew. It was further found through experiments that benzamid with different mechanisms of action and isopropyl The combination of Thiafluoride has unexpected effects, not only has a significant synergistic effect, but also has a better control effect on the highly resistant cucumber downy mildew, thereby reducing the amount of medication and reducing the cost of control
