Description
The application is a kind of divisional application of " bactericidal composition containing chitosan oligosaccharide " application for a patent for invention, original application day：
On January 2nd, 2014, application number：2014100012437
Technical field
The present invention relates to a kind of bactericidal composition containing chitosan oligosaccharide, composition for prevent and treat banded sclerotial blight, downy mildew, smut,
The multiple diseases such as anthracnose, late blight, leaf spot, scab.
Background technology
Come from organism and the great interest of the good compound of the biodegradability person that caused pesticide research.At this
In a little compounds, have no toxic side effect, the chitosan oligosaccharide of easily biological-degradable has very big potentiality, the new medicament as control disease.
Chitosan oligosaccharide leads antiviral agents as the important plant inducer of a class, and from the research of the oligosaccharide of plant, research shows that chitosan oligosaccharide exists
During resisting pathogen erosion, it can induce and excite plant to produce a series of defense reaction, the collaboration of these defense reactions is made
With the propagation and invasion for preventing pathogen, the effect prevented and cured diseases is reached.Meanwhile, chitosan oligosaccharide is also the new plant hormone of a class,
With adjusting and controlling the effect such as growth and development of plants, it can send the information of regulation specified plant function, and these functions include
Growth promotion, cold-resistant, drought resisting etc..
Fluopicolide, thifluzamide, fluorine azoles bacterium aniline, fluxapyroxad sterilization component are the emerging sterilizations of pesticide market
Agent, all contains amide groups, mechanism of action is mainly suppression pathogen succinate dehydrogenase, so as to disturb it in terms of chemical constitution
Respiration.For Reasonable Protection such medicament, delay germ generation drug-fast to new medicament and improve the prevention effect of medicament,
It is necessary to carry out rational composition research.There is presently no the report on chitosan oligosaccharide and above-mentioned sterilization component composition research.Hair
The research that a person of good sense passes through the compounding effect to bactericidal composition, it was found that some unexpected effects.
The content of the invention
It is an object of the invention to provide a kind of chitosan oligosaccharide bactericidal composition, by two kinds of different structures, the different mechanisms of action
Sterilization component compounded, be expand preventing and treating spectrum and improve drug effect effective way, it is often more important that avoid or delay disease
Generation to new composition resistance.The purpose of the present invention is realized by following measures.
The invention provides a kind of bactericidal composition containing chitosan oligosaccharide, it is characterised in that said composition includes the A of effective dose
With two kinds of active components of B, wherein A is chitosan oligosaccharide, and B is in fluopicolide, thifluzamide, fluorine azoles bacterium aniline, fluxapyroxad
One kind.
In above-mentioned bactericidal composition, the quality parts ratio between the component of A, B two is 1：10-10：1, it is preferred that mass fraction
Than for 1:5-5:1.
In above-mentioned bactericidal composition, the quality sum of component A and B component accounts for the 1- of bactericidal composition gross mass percentage
60%.
Above-mentioned composition of the present invention can be made into suspending agent, wettable powder, water dispersible granules, aqua, microemulsion, water and milk
Agent, for spraying, pouring root, seed dressing etc..
It is used for the purposes for preventing and treating crop disease present invention also offers above-mentioned composition, the disease suitably prevented and treated has basidiomycetes
Banded sclerotial blight, smut etc. caused by subphylum, the fungus-caused downy mildew of Mastigomycotina, epidemic disease, peronospora tabacina etc., Fungi Imperfecti
Fungus-caused scab, the fungus-caused anthracnose of Ascomycotina, leaf spot etc..Therefore, present invention additionally comprises above-mentioned group
The purposes of various agricultural fungal diseases on Researches On Hydrate Prevention crop.
It has also been found that, above-mentioned bactericidal composition is in the case where respective active component is reduced using total amount, to paddy rice
Banded sclerotial blight, cucumber downy mildew, wheat smut have excellent prevention effect, and synergistic effect is obvious.
In the purposes of above-mentioned composition of the present invention, the crop is paddy rice, wheat, cucumber, capsicum, watermelon, apple, Portugal
Grape, citrus, pears, lichee, flowers etc..
In the present invention, chitosan oligosaccharide is the high score that the degree of polymerization that Glucosamine is formed by connecting by Isosorbide-5-Nitrae-glycosidic bond is 2-30
The mixture of sub- polymer, mean molecule quantity is 1000-3000 dalton.Current chitosan oligosaccharide is the macromolecule of different polymer
The mixture of polymer, that is to say, that be not the oligosaccharides form of the single degree of polymerization in chitosan oligosaccharide, but the shell of every kind of degree of polymerization
Oligosaccharides monose all there may be.Which kind of so no matter being prepared by method, or prepared by above-mentioned preparation method
Commercially available prod, as long as its degree of polymerization that to be Glucosamine be formed by connecting by Isosorbide-5-Nitrae-glycosidic bond is 2-30, mean molecule quantity
It is exactly chitosan oligosaccharide of the present invention for the mixture of the high molecular polymer of 1000-3000 dalton.
Present invention has the advantages that：
1st, synergistic effect is obvious：Composition shows good synergistic effect in certain ratio range, improves composition
Protection effect.
2nd, preventing and treating spectrum is expanded：Composition can prevent and treat the multiple diseases in agricultural production.
3rd, use cost is reduced：Preventive effect, preventing and treating spectrum increase are improved because compounding has, access times are reduced, reducing makes
Use cost；
4th, the resistance to the action of a drug is delayed：The composition compounding of two kinds of different mechanism of action, pathogen is not likely to produce the resistance to the action of a drug, delays cause of disease
Bacterium is drug-fast to medicament to be produced.
