Abstract

The invention relates to a sterilization composition which takes iminoctadine tris and wuyiencin as effective components, wherein the mass ratio between the iminoctadine tris and the wuyiencin is (50-1):(1-20). The compound preparation for controlling wheat powdery mildew is remarkable in synergism and has the effect up to more than 90%, and the effect of the compound preparation is obviously higher than that of the single preparation. The compound preparation is good in fast-acting property and persistence and more in mechanisms and points of action, and can effectively delay the growth and development of drug resistance of pathogenic bacteria, thus reducing the absolute dosage of pesticide and reducing the environmental pollution. The compound preparation is simple in preparation technology, low in cost, remarkable in economical benefit, wide in disease prevention spectrum and high in biosecurity, and has remarkable function of increasing the yield.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a fungicidal composition for preventing and treating wheat powdery mildew. Background technique [0002] Biguanide trioctylbenzenesulfonate, chemical name: 1,1-octylmethylene biguanide trioctylbenzenesulfonate. Biguanide trioctylbenzenesulfonate is a broad-spectrum, low-toxic fungicide, which inhibits the biosynthesis of lipid compounds in pathogenic bacteria, has strong local penetration, and has high growth inhibitory activity against pathogenic Ascomycetes and Deuterobacteria. [0003] Wuyiencin can inhibit the protein synthesis of pathogenic bacteria, and inhibit the mycelium growth, spore formation, germination and affect the cell membrane permeability of pathogenic bacteria, and change the narrow concept of simple bactericidal health control; Wuyiencin can adjust the health of crops 1. Reasonable plant type, reasonable root / shoot ratio, appropriate leaf surface coefficient, suita...
