Problems solved by technology

Thiophanate-methyl interferes with the cell division process and has systemic protective and therapeutic effects on crops. It is easily permeated and transformed into carbendazim in plants, which interferes with the formation of the spindle in mitosis and affects cell division. It is effective against botrytis and Fusarium Bacteria, Microwilts, Penicillium, Septoria, Sclerotinia, Black Star, Verticillium, Rhizoctonia have good control effects, but have no effect on algal fungi and bacteria
Tebuconazole is a systemic fungicide, which can inhibit the demethylation of sterols, and can prevent and control the diseases caused by Rust, Powdery Mildew, Corythospora, Sclerotinia and Septoria, but it is not effective for the epidemic Mold and dry rot are less effective

Abstract

A composite bactericide with synergistic action for preventing and eliminating the diseases and pests of fruit tree, grapevine, vegetables, watermelon, wheat and rice is prepared from tebuconazole (2-25 Wt%), thiophanate-methyl (10-75), assistant (3-25) and filler (10-70).

Description

technical field [0001] The present invention relates to a fungicide composition with a synergistic effect, which exhibits extremely strong antibacterial and bactericidal activities, and is used in the field of agricultural phytochemical protection, mainly for the prevention and treatment of fruit trees, grapes, vegetables, watermelons, wheat, and rice The fungicide is harmless and has protective and therapeutic effects on crops, and the fungicide composition is different from other existing fungicide compositions. Background technique [0002] As we all know, thiophanate-methyl and tebuconazole are effective fungicides. Thiophanate-methyl interferes with the cell division process and has systemic protective and therapeutic effects on crops. It is easily permeated and transformed into carbendazim in plants, which interferes with the formation of the spindle in mitosis and affects cell division. It is effective against botrytis and Fusarium Bacteria, Microwilt, Penicillium, S...
