Description

The bactericidal composition of compounded by diniconazole and tea saponin, its preparation method and application
Technical field
The invention belongs to agricultural bactericidal preparation technique field, be specifically related to a kind of bactericidal composition its preparation method and application of compounded by diniconazole and tea saponin.
Background technology
Because long-term, a large amount of unreasonable uses of chemical pesticide, and because the intrinsic shortcoming of some medicament itself has caused serious pesticide resistance problem.It is good to seek Environmental compatibility, and the public nuisance-free agricultural chemicals to pathogen has lasting effect seems especially important in today that pollution-free food is much accounted of day by day.
Natural products often shows many biologically actives, and widely people are used for hundreds of years.Wherein, the research and development of plant resource fungicide active ingredient is an important research direction that solves the many negative effects of current chemical bactericide.Therefore, be object with the natural products, seek bioactivator, the research and development novel biopesticide enjoys attention at home and abroad, and wherein, botanical pesticide is a most noticeable class.Being mixed of the exploitation of botanical pesticide, botanical pesticide and chemical pesticide, botanical pesticide and being mixed of botanical pesticide all are the forward position and the focus of pesticide research in the world.
Alkene azoles alcohol is wide-spectrum bactericide, belong to triazole bactericidal agent, spray and can prevent the smelting smut of being scattered about like the stars on grape, cereal and fruit, this bactericide also can be used to the powdery mildew of anti-smelting rose, the leaf spot of peanut, the leaf spot of banana and the powdery mildew of coffee, in the ergosterol biosynthesis of fungi, suppress 14 α-demethylation effect, cause that ergosterol lacks, and causes fungal cell membrane undesired, final fungi death, the lasting period is permanent.
Tea Saponin (Tea saponin) is the bactericide that extracts from the tea cake after the seed of plant of theaceae such as tea seed cake, the tea-seed oil expression, belongs to pentacyclic triterpenoid, and its pure product are colorless prismatic crystal, have hygroscopicity, and bitter is pungent, and molecular formula is C 57H 90O 26, molecular weight is 1191.31,223~224 ℃ of fusing points, and soluble in water and organic solvents such as alcohols, organic acid are insoluble to organic solvents such as ether, benzinum, benzene.
Tea Saponin is a kind of nonionic surface active agent, has that stronger exhibition is puted forth effort, emulsifying ability, dispersion force, wetting power and a foaming power, and cold-blooded animal is had high poison, and people and animals are waited the nontoxic or low toxicity of homoiothermy animal.This compound has sterilization, sterilization, kills mite and reduces capillary multiple function, has different mechanism of action with chemical pesticide, and by improve soup wetting, opening up, emulsifying dispersivity has significant synergies to chemical pesticide.Tea Saponin is typical no-pollution multifunctional plant pesticide kind, and for example at Chinese countryside, the tea bran always is exactly a soil pesticide, can kill oncomelania as pool-cleaning agent, makes bactericide with immersion tea bran water and can prevent rice blast and banded sclerotial blight.After deliberation, Tea Saponin itself has good inhibition effect to the various plants growth of pathogenic bacteria, is a kind of typical multi-functional plant source pesticide kind.But this medicine quick-acting is poor, and application dosage is very big when using separately.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing bactericide technology, make full use of the unique effect mechanism of rich resources of tea saponin and its botanical pesticide, determine the suitable compatibility of itself and alkene azoles alcohol, a kind of efficient, wide spectrum is provided, is difficult for developing immunity to drugs, the bactericidal composition of low toxicity.
