The invention also provides the use of the composition for preventing and controlling multiple agricultural fungal diseases of crops. The composition has a good synergistic effect within a certain proportion range, a disease prevention effect of the composition is improved, and the generation of resistance of pathogenic bacteria to pesticides is retarded.
Description
The application is the divisional application of " a kind 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 chitosan oligosaccharide bactericidal composition, composition is used for preventing and treating the multiple diseases such as banded sclerotial blight, downy mildew, smut, anthracnose, late blight, leaf spot, scab.
Background technology
Come from organism and the great interest of the good compound of biodegradability has caused pesticide research person.In these compounds, have no side effect, the chitosan oligosaccharide of easily biological-degradable has very large potentiality, become the new medicament controlling disease.Chitosan oligosaccharide is as the important plant inducing anti-disease agent of a class, derive from the research of the oligosaccharide of plant, research shows, chitosan oligosaccharide is in the process resisting pathogen erosion, can induction plant be excited to produce a series of defense reaction, these defense reactions synergy stops propagation and the invasion of pathogen, reaches the effect of preventing and curing diseases.Meanwhile, chitosan oligosaccharide is also the plant hormone that a class is new, has the effects such as regulation and control growth and development of plants, and it can send the information regulating specified plant function, and these functions comprise growth promotion, cold-resistant, drought resisting etc.
Fluopicolide, thifluzamide, fluorine azoles bacterium aniline, fluorine azoles bacterium acid amides sterilization component are the emerging bactericide of pesticide market, and in chemical constitution, all contain amide groups, mechanism of action mainly suppresses pathogen succinate dehydrogenase, thus disturbs its respiration.For such medicament of Reasonable Protection, delay germ to the drug-fast generation of new medicament and the control efficiency improving medicament, be necessary to carry out rational composition research.Also there is no the report about chitosan oligosaccharide and above-mentioned sterilization component composition research at present.Inventor, by the research to the composite effect of bactericidal composition, has found some beyond thought effects.
Summary of the invention
The object of the present invention is to provide a kind of chitosan oligosaccharide bactericidal composition, the sterilization component of two kinds of different structures, the different mechanism of action is carried out composite, be expanding prevention spectrum and the effective way improving drug effect, the more important thing is and avoid or delay the generation of disease to new composition resistance.The object of the invention is to be realized by following measures.
The invention provides a kind of bactericidal composition containing chitosan oligosaccharide, it is characterized in that said composition includes A and B two kinds of active components of effective amount, wherein A is chitosan oligosaccharide, and B is selected from the one in fluopicolide, thifluzamide, fluorine azoles bacterium aniline, fluorine azoles bacterium acid amides.
In above-mentioned bactericidal composition, the ratio of quality and the number of copies of A, B two between component is 1:10-10:1, and preferably, ratio of quality and the number of copies is 1:5-5:1.
In above-mentioned bactericidal composition, the quality sum of component A and B component accounts for the 1-60% of bactericidal composition gross mass percentage.
Above-mentioned composition of the present invention can be made into suspending agent, wetting powder, water dispersible granules, aqua, microemulsion, aqueous emulsion, for spraying, fills with root, seed dressing etc.
Present invention also offers above-mentioned composition for preventing and treating the purposes of crop pest, banded sclerotial blight, smut etc. that suitable disease of preventing and treating has Basidiomycotina to cause, the fungus-caused downy mildew of Mastigomycotina, epidemic disease, peronospora tabacina etc., the fungus-caused scab of Fungi Imperfecti, the fungus-caused anthracnose of Ascomycotina, leaf spot etc.Therefore, the present invention also comprises the purposes of various agricultural fungal diseases on above-mentioned composition control crop.
The present invention also finds, above-mentioned bactericidal composition is when respective active component uses total amount to reduce, and have excellent control efficiency to rice sheath blight disease, cucumber downy mildew, wheat smut, synergistic effect is obvious.
In the purposes of above-mentioned composition of the present invention, described crop is paddy rice, wheat, cucumber, capsicum, watermelon, apple, grape, oranges and tangerines, pears, lichee, flowers etc.
In the present invention, chitosan oligosaccharide is Glucosamine is the mixture of the high molecular polymer of 2-30 by the degree of polymerization that Isosorbide-5-Nitrae-glycosidic bond is formed by connecting, and mean molecule quantity is 1000-3000 dalton.Current chitosan oligosaccharide is the mixture of the high molecular polymer of different polymer, be not that is the oligosaccharides form of the single degree of polymerization in chitosan oligosaccharide, but the chitosan oligosaccharide monose of often kind of degree of polymerization all may exist.So no matter by which kind of method prepared, or by the commercially available prod that above-mentioned preparation method prepares, as long as its be Glucosamine by the degree of polymerization that Isosorbide-5-Nitrae-glycosidic bond is formed by connecting be 2-30, mean molecule quantity be the mixture of the daltonian high molecular polymer of 1000-3000 is exactly chitosan oligosaccharide of the present invention.
Beneficial effect of the present invention is:
1, synergistic effect is obvious: composition shows good synergistic effect in certain ratio range, improves the protection effect of composition.
2, expanding prevention spectrum: composition can prevent and treat the multiple diseases in agricultural production.
3, use cost is reduced: because of composite, there is raising preventive effect, the increase of control spectrum, decrease access times, reduce use cost;
4, delay pesticide resistance: the composition of two kinds of different mechanism of action is composite, and pathogen not easily develops immunity to drugs, delay pathogen to the drug-fast generation of medicament.
