The present invention relates to a kind of bactericide compounded thing containing oligosaccharides, wherein oligosaccharide kind including sodium alginate oligosaccharide and its derivative, chitin oligo saccharide and its derivative, oligogalacturonans and its derivative etc. one or more, a kind of and broad-spectrum germicide jinggangmeisu.The two is mixed by different proportion, soluble compounding agent is formed it into.Few carbohydrates and their derivative consumption 2.5-10%, jinggangmeisu consumption 1.5-24% in built agent, add the double property particle hydrotropies of 1-5%, and 1000 times of dilution is used, and fungistatic effect reaches 45-95%.With few carbohydrates and their derivative and composite jinggangmycin the preparation primary characteristic such as jinggangmeisu bactericide spectrum can be kept efficient, safety low-poison, and increase oligosaccharides biological pesticide, reduce antibiotic dosage, improve the reaction of crop self-defense and crop yield, improve quality of agricultural product, security, development environment close friend's novel built bactericide are applied in enhancing.
Description
Technical field
Prepared with the agent of bactericide composite jinggangmycin with oligosaccharides or oligosaccharide derivative the present invention relates to one kind and applied on preventing and treating phytopathogen.
Background technology
Agricultural is the basis of human society and economic development, and plant disease is the big factor for restricting agricultural sustainable development, and control of plant disease holds the balance in sustainable agriculture.As chemical Agrotechnical formulation is abused, phytopathogen gradually makes a variation and increase with the resistance to the action of a drug, more wreaks havoc.Finding safe and efficient, environment-friendly new agricultural chemicals turns into the most important thing.
Jinggangmeisu is that 20 century 70 China successfully develop a kind of farm antibiotics with entirely autonomous intellectual property, and jinggangmeisu is strong absorbability, the antibioticses bactericide of tool selection index system.Category is efficient, low toxicity bactericide.Jinggangmeisu is used more than 40 years in China, is not likely to produce the resistance to the action of a drug.Jinggangmeisu has special efficacy to preventing and treating rice sheath blight disease, it can also be used to rice green smut, wheat sharp eyespot etc..In decades for the cereal crops stable high yield of China is made that major contribution.The subject matter that presently, there are is that jinggangmeisu range of application is narrower, and controlling disease species is less, and alone jinggangmeisu is undesirable to rice sheath blight disease and other disease-controlling effects, also less stable, to the Common Diseases effect on driving birds is not good of other industrial crops.So it is accomplished by repeatedly, dosage sprays, to maintain the control effect to rice sheath blight disease.Agriculture sheet is which increased, effect on environment is also increased, while also to constituting considerable influence to agricultural product quality.
Oligosaccharide kind material is applied to plant protection art from the seventies in last century; with suppression phytopathogen, induction disease resistance of plant, promote the functions such as plant growth; this kind of oligosaccharides material is specially named as oligosaccharide biological pesticide, have the advantages that relative molecular mass is small, toxicity is low, good water solubility, absorbability it is strong.Oligosaccharide kind material will be mixed with bactericide or antibiotic, improve the effect of bactericide, can reduce the consumption of bactericide or antibiotic, and prevention and treatment range is expanded to some bactericide.Oligosaccharide kind material and composite jinggangmycin, can play the speciality of the two, and effect well can be played on control of plant disease.Oligosaccharide kind material has no document and patent report with composite jinggangmycin as controlling plant diseases novel agrochemical.
The content of the invention
Soluble aqua as the safe and effective Recompounded pesticide of controlling plant diseases and its application method is mixed to form using oligosaccharide kind material and jinggangmeisu according to a certain percentage it is an object of the invention to provide one kind.
To achieve the above object, the technical solution adopted by the present invention is：
1. broad spectrum activity oligosaccharides composite bactericide of the present invention, active ingredient is one or two or more kinds in oligosaccharides or oligosaccharide derivative, and jinggangmeisu；Wherein oligosaccharides or the oligosaccharide derivative content in built agent is 2.5-10%；Jinggangmeisu content in built agent is 1.5-24%；Remaining is auxiliary agent.
2. oligosaccharides is one or two or more kinds in sodium alginate oligosaccharide, chitin oligo saccharide, oligogalacturonans, carrageenan oligosaccharide and Portugal's oligosaccharides in composite bactericide of the present invention；Oligosaccharide derivative is one or two or more kinds in oligosaccharides sulfate derivative, oligosaccharides phosphoric acid derivatives, oligosaccharides sulphonamide derivatives, oligosaccharides acylisothiocyanate analog derivative, oligosaccharides phosphorous derivant, oligosaccharides guanidine derivative, oligosaccharides nicotinoyl isocyanate derivative, oligosaccharides-cerium (IV) complex compound；Jinggangmeisu active ingredient is mainly jinggangmycin A；One kind in the auxiliary agent isopropanol, dichloromethane or two kinds.
3. broad-spectrum germicide provided by the present invention can be used for cereal crops, industrial crops, commodity trees, Chinese medicine, flowers or lawn；When disease occurs, the fungal diseases such as droop, powdery mildew, banded sclerotial blight, rot can be effectively prevented and treated, and one or two or more kinds in the virosis such as mosaic disease.
4. broad-spectrum germicide provided by the present invention has for corps diseases and protects and treatment double action; in premorbid infection process is not received using the plant that can protect the health; disease can be controlled to spread after morbidity; possess multi-faceted sterilized site; germ is not likely to produce the resistance to the action of a drug; while controlling disease, via plant immunity can be effectively improved, induction plant produces disease resistance；Composite bactericide bacteriostasis rate is up to 45-95%；Plant rate of growth reaches 10-30%.
5. the application process of broad-spectrum germicide of the present invention is one or two or more kinds processing mode spray, soak seed, being stained with root and pouring root, for processing one or two or more kinds in vegetable seeds, seedling or strain；Applied after 1000 times of dilution.
The invention has the advantages that：
1 reduces jinggangmeisu usage amount, adds the more preferable oligosaccharide kind material of biocompatibility, green, environmentally friendly, environment-friendly.
2 oligosaccharide kind material wide material sources, cheap, operating process is simply harmless, and complex agent type is aqua, without a large amount of adjuvants are added, using simplicity, is adapted to large-scale promotion and application.
3 present invention to pathogenic microorganism in addition to directly working, moreover it is possible to adjusts plant immune, induces disease resistance of plant, and drug effect becomes apparent from, more longlasting, reduction Pesticide use amount, and will not develop immunity to drugs.
Built agent and pure chemistry preparation effect quite, can partly substitute chemical pesticide and use in 4 present invention, and reduction agriculture is residual, solve food-safety problem.
