Sterilization composition containing pydiflumetofen and fenpyrazamine

Abstract

The invention discloses a sterilization composition containing pydiflumetofen and fenpyrazamine and application thereof. Effective active ingredients consist of a first active ingredient (pydiflumetofen) and a second active ingredient (fenpyrazamine), and the weight ratio of the first active ingredient to the second active ingredient is 1:60-60:1, preferentially 1:30-30:1. The composition can be prepared to be agriculturally allowable wettable powder, water dispersible granules, a suspending agent, a suspoemulsion, an emulsion in water, a microemulsion, a microcapsule suspending agent, a microcapsule suspension-suspending agent, a dispersible oil suspending oil and a dry suspending agent. The sterilization composition has the advantages that the ingredients are reasonable, the sterilization effect is good, the activity and sterilization effect are not simply overlapped of activities of the ingredients, has an obvious sterilization effect and obvious synergism, and is beneficial to cropsafety compared with the existing single preparation. The sterilization composition has obvious prevention and treatment effects on botrytis cinerea, powdery mildew, brown rot, stalk break and venturia inaequalis.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient, flufenapyramide, a second active ingredient, pyraffenone, and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Flumetofen, English common name pydiflumetofen, chemical name: 3-(difluoromethyl)-N-methoxy-1-methyl-N-[(RS)-1-methyl-2-(2 , 4,6-trichlorophenyl)ethyl]pyrazole-4-carboxamide. Flufenapyramide is a pyrazole amide fungicide discovered, developed and produced by Syngenta. It was launched in 2017. It is the latest product to be launched among SDHI fungicides. Fluconazole hydroxylamide is highly efficient and broad-spectrum, suitable for cereals, corn, soybeans, rapeseed, vegetables and special crops, etc., to control gray mold, brown spot, leaf spot, sclerotinia, powdery mildew, scab Many diseases, etc. Among all chemical types of products, flufenapyramide has the highest activity agains...

AI Technical Summary

Problems solved by technology

[0004] After searching, the applicant found that there is currently no report on the mixing of flufenapyroxylamide and fenflufen to prevent and control plant fungal diseases. Further tests have found that the combination of flufenapyroxylamide and fenflufen with different mechanisms of action The compound has unexpected effects, and has a good control effect on fungal diseases such as crop-resistant gray mold, powdery mildew, brown rot, sclerotinia and scab. The synergistic effect is obvious, and the dosage is reduced. Reduced control costs, safe for crops
