Abstract
The invention discloses a bactericide composition with a synergistic effect, and relates to the agricultural science and farming techniques, in particular the technical field of production of pesticide. The composition bactericide comprises the following raw materials in weight percent: 5-45% of kresoxim-methyl and 2-43% of tebuconazole. The composition has powerful bactericidal activity, and is used for preventing and controlling various diseases in apple tree, grape, tomato, cucumber, strawberry and wheat. The composition has the effects of protecting and treating the crops, and the composition bactericide is different from other existing pesticide bactericide.
Description
Technical field
The present invention relates to agricultural cience and farming techniques, particularly the production technical field of agricultural chemicals.
Background technology
Kresoxim-methyl, Chinese is kresoxim-methyl, English common name: kresoxim-methyl, it is the novel antibiotics bactericide of a kind of bio-mimetic syntheses, kresoxim-methyl acts on cytochrome compound, block the electron transfer process of germ mitochondrial respiratory chain, suppress the supply of germ cellular energy, germ cell is made to lack energy dead, to imperfect fungus, sac fungi, basidiomycetes, the fungus-caused multiple diseases such as Oomycete has good activity, there is good protection, treat and root out activity, to crop, people, poultry and beneficial organism safety, substantially pollution-free to environment.
Tebuconazole, English common name: tebuconazole is systemic fungicide, suppresses sterol demethylation, and control Rust that can be fabulous, Erysiphe, Rhynchosporium spp．, nuclear cavity Pseudomonas and Sales pin spore belong to the disease caused, but to phytophthora, dry rot fungus weak effect.
Summary of the invention
The object of the invention is, for above-mentioned weak point, to provide one to have synergic bactericide composition.
Active ingredient of the present invention is made up of kresoxim-methyl and Tebuconazole, and kresoxim-methyl accounts for 5 ~ 45% of composition gross mass, and Tebuconazole accounts for 2 ~ 43% of composition gross mass, and all the other are auxiliary agent and filler.
The present invention shows extremely strong antibacterial and bactericidal activity; be applied to agricultural plant chemoproection field; especially in control apple tree, grape, tomato, cucumber, strawberry, all kinds of disease of wheat; have protective effect and therapeutic action to crops, said composition bactericide is different from other microbicide compositions existing.Prove after tested, microbicide compositions stable chemical nature of the present invention, synergy is remarkable, shows obvious synergy and complementation to controlling object.
Kresoxim-methyl and Tebuconazole composite, there is obvious synergistic effect, expand fungicidal spectrum simultaneously, apply in apple tree, grape, tomato, cucumber, all kinds of disease of wheat, control efficiency is good, be better than kresoxim-methyl, Tebuconazole two medicaments are alone, agriculture can be reduced originally, between the two without cross resistance simultaneously.
The present invention adds auxiliary agent and filler can be made into wetting powder or suspending agent.
In order to form the auxiliary agent of suspending agent, the present invention also comprises the dispersion moisture agent accounting for composition gross mass 1 ~ 15%, the alcohols antifreeze accounting for composition gross mass 1 ~ 3%, the thickener accounting for composition gross mass 2 ~ 5%, accounts for organic defoamer of composition gross mass 0.05 ~ 2%.
