Description
Technical field
The invention belongs to composition pesticide field, and in particular to be a kind of killing comprising benzothiostrobin and amino-oligosaccharide
Bacteria composition and its application.
Background technology
Benzothiostrobin is a kind of strobilurin fungicide of Central China Normal University's research and development, and it has sterilization
The advantages of spectrum is wide, bactericidal activity is high, amount of application is low, the lasting period is long, has treatment and protective effect concurrently, not only to cucumber downy mildew and
Powdery mildew has good preventive effect, for scab, anthracnose, gray mold, corn southern leaf blight, false smut, banana blight, banana
Sigatoka leaf spot disease has excellent inhibitory activity, but long-term exclusive use easily makes disease develop immunity to drugs.
Amino-oligosaccharide（Chitosan oligosaccharide）Refer to oligosaccharide that D- Glucosamines are connected with β -1.4 glycosidic bonds, by chitin
Degrade to degrade again after shitosan prepared, or the low toxicity bactericide extracted by microbial fermentation.Amino-oligosaccharide can be to some diseases
The growth of bacterium produces inhibitory action, influences the sprouting of fungal spore, induces that hypha form morphs, biochemistry changes in spore
Deng.Gene in energy activated plant body, produces the chitinase with resistant effect, dextranase, protects element and PR albumen etc., and have
Cell activation is acted on, and contributes to the recovery of aggrieved plant, and promoting root growth strong sprout strengthens the resistance of crop, promotes growth and development of plants.
Amino-oligosaccharide solution has antivirus, bactericidal, fungicidal action.Not only to bacterium, fungi, virus with extremely strong preventing and treating and
Eradicant action, but also with nutrition, regulation, removing toxic substances, the effect of antibacterial.Not only fungi, bacterium, virus are prevented with extremely strong
Control and eradicant action, but also there is nutrition, regulation, removing toxic substances, antibacterial.Can be widely used for preventing and treating fruit tree, vegetables and cotton
The diseases such as mosaic disease, little leaf, spot disease, anthracnose, downy mildew, epidemic disease that grain crop causes.
In the real process of agricultural production, using two or more active component pathogen can be delayed disease-resistant
Property generation, extend the service life of single active component.Thus, exploitation is efficient with research, the complex preparation of low toxicity, low-residual
Have the advantages that small investment, R＆D cycle are short, thus paid attention to by domestic and international research and development institution.Present inventor is indoors
On the basis of screening and field control effectiveness test, prove benzothiostrobin and amino-oligosaccharide in certain ratio by substantial amounts of experiment
Interior compounding has obvious synergistic effect to various plants disease fungus, it is possible to reduce applications of pesticide amount, delay the anti-medicine of pathogen
The generation of property, and then complete the present invention.At present, it is not yet found that the related report compounded on benzothiostrobin and amino-oligosaccharide
Road.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, there is provided it is a kind of to have treatment concurrently and the synergy of protective effect is killed
Bacteria composition, said composition prevention effect is good, wide sterilization spectrum, resistance are low.
Application another object of the present invention is to provide the bactericidal composition, in particular for preventing and treating cucumber downy mildew.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of bactericidal composition, it is characterised in that active component includes benzothiostrobin and amino-oligosaccharide, wherein, benzothiostrobin
It is 1 with the weight ratio of amino-oligosaccharide:40-40:1, preferably 1:20-10:1.
Further, the weight ratio of active component is 1-90%, preferably 10-50% in the bactericidal composition.
Further, bactericidal composition of the invention also contains the auxiliary for allowing to use and help to play drug effect in agricultural chemicals
Composition.
Further, bactericidal composition of the invention is aided with auxiliary element by conventional system by by pesticide activity component
Preparation Method is prepared into any one formulation in Pesticide formulation, selected from missible oil, wettable powder, water dispersible granules, suspension
Agent, aqueous emulsion, microemulsion, dispersible any one in oil-suspending agent, seed coat agent.
Composition of the invention can be that each material is blended in composition with finished product preparation form offer, it is also possible to
Unit dose form is provided, and is directly mixed in proportion in bucket or tank using preceding, is then diluted to required concentration.
Further, composition of the invention can also add other agricultural active compositions, for example bactericide, insecticide,
The agricultural active composition such as herbicide, fertilizer.
Further, bactericidal composition of the invention is used to prevent and treat the multiple diseases such as downy mildew, gray mold, anthracnose, powdery mildew.
Compared with prior art, beneficial effects of the present invention are：Benzothiostrobin and amino-oligosaccharide are in certain ratio model
Compounded in enclosing, had obvious synergistic effect, simultaneously as the mechanism of action of active component benzothiostrobin and amino-oligosaccharide
It is different, the drug-fast generation of pathogen can be delayed；In addition, the action spectrum of active component benzothiostrobin and amino-oligosaccharide
Extensively, multiple diseases are respectively provided with it is simultaneous control effect, can reduce spraying times using composition pesticide of the invention, save medication
Cost；3rd, composition pesticide preparation process is simple of the invention, raw material are easy to get, the highly popularization and application in production.
