Abstract
The invention relates to a biological bactericide composition and an application thereof to a wilt. The biological bactericide composition comprises active components including amino-oligosaccharin and bacillus subtilis, wherein the weight content of the amino-oligosaccharin is 0.5-5%; the content of the bacillus subtilis is 1.0-1,000.0 hundred million active spores per gram. The biological bactericide composition disclosed by the invention is testified by a field trial and has good prevention and treatment effects on watermelon and melon wilts; meanwhile, all the active components are compounded to further improve the prevention effect and the prevention effect is obviously better than that of a single-dosage variety.
Description
Technical field
The present invention relates to a kind of biological bactericide composition and the application on fusarium wilt thereof.
Background technology
Bacillus subtilis is a kind of have a liking for temperature, aerobic, sporiferous bacillus, and its physiological characteristic is various, and is widely distributed, very easily separates and cultivates.This bacterium is widespread in nature, and is nontoxic to people and animals, free from environmental pollution, can produce multiple antibiotic and enzyme, has broad spectrum antibiotic activity and extremely strong anti-adversity ability.Bacillus subtilis not only can be in the external environments such as soil, plant rhizosphere body surface extensively exists, and is common endogenetic bacteria in the plant corpus, especially in root, the stem of plant.This bacterium demonstrates good disease-controlling effect crops such as paddy rice, cotton, capsicum, tomato flowers at present.The prominent features such as growth is fast because bacillus subtilis has, nutrition is simple and it is heat-resisting to produce, degeneration-resistant gemma, producing, formulation and the survival in environment, surely growing and breeding and make it not only be conducive to biocontrol fungicide, and mass production processes is simple, cost is lower, use conveniently, storage life is long, has now become a kind of desirable biocontrol bacteria.
Amino-oligosaccharide (chitosan oligosaccharide) is the further product of degraded of chitosan, shitosan is a kind of polysaccharose boiomacromolecule, be widespread in nature in the unicellular lower eukaryote mushroom, the cell of algae, the shell of a joint animal shrimp, crab, insect, inner casing and the cartilage of mollusk (such as squid, cuttlefish), the cell wall of higher plant etc., the synthetic resource of annual life can reach 2,000 hundred million tons, being the second largest living resources that are only second to vegetable fiber on the earth, is human inexhaustible living resources.
Amino-oligosaccharide (agricultural level chitosan oligosaccharide) can produce inhibitory action to the growth of some germs, affect fungus spore germination, brings out that the mycelia form morphs, the interior biochemistry of spore changes etc.Can excite the plant vivo gene, produce and to have chitinase, dextranase, guarantor's element and the PR albumen etc. of resistant effect, and have the cell activation effect, the recovery of the plant that helps to be injured strengthens the resistance of crop at short root strong sprout, and Promoting plant growth is grown.The amino-oligosacchride cellulose solution has virus killing, kills bacterium, fungicidal action.Not only fungi, bacterium, virus are had extremely strong control and eradicant action, but also have nutrition, adjusting, detoxifcation, antibiotic effect.Can be widely used in the diseases such as virus, bacterium, fungus-caused mosaic disease, little leaf, spot disease, anthracnose, downy mildew, epidemic disease, climing rot, verticillium wilt, rice blast, bacterial wilt, soft rot of control fruit tree, vegetables, underground rhizome, tobacco, traditional Chinese medicine and grain and cotton crop.
Induce the sterilization pesticide chitosan oligosaccharide with advantages such as its wide material sources, the growths of the high also energy of induce resistance coordinate plant growth, become gradually the domestic and international focus of attention.As biopesticide, chitosan oligosaccharide diseases prevention and disease-resistant aspect number of mechanisms is arranged, except as active signaling molecule, excite rapidly the defense response of plant, start system of defense, make plant produce the disease-resistance substances such as phenolic compound, lignin, protective plant protecting agent, pathogenesis-related proteins, and the raising defensive ferment relevant with disease-resistant metabolism and the Active oxygen eliminating enzyme system activity of uniting, oligosaccharides also is its disease-resistant necessary component to the direct inhibitory action of phytopathogen.
At present, the amino-oligosaccharide formulation products mainly contains 1%, 2%, 3% and 5% amino-oligosaccharide aqua etc., is mainly used in vegetables, fruit tree prevents and treats the effects such as virus disease, late blight and growth regulation, enhancing resistance.But its unitary agent is obvious not as the chemical agent preventive effect because of bactericidal effect, do not accepted and pay attention to by the producer, therefore extensive not on the purposes on producing, do not give full play to the effect of amino-oligosaccharide, the bacillus subtilis action effect is different because of applying environment, and effect is stable not.By to carry out science composite from different pharmacy varieties, be the control germ and improve preventive effect, the convenient effective way of using.The relevant built agent kind of amino-oligosaccharide and bacillus subtilis is all less at present, can not satisfy the needs of producing upper crops control of crop disease.
West (sweet) cucurbit wilt is a kind of fungoid soil-borne disease, fusarium wilt: be commonly called as dead arm, wilt disease, its cause of disease is Fusarium oxysporum, can fall ill whole breeding time, and knot melon phase and to expand the later stage be two peaks has a strong impact on the yield and quality of west (sweet) melon.During morbidity, the jaundice of plant lower blade is upwards development gradually, and wilt daytime, sooner or later recovers, and is dead after several days.Germ survives the winter in soil or the fertilizer that carries disease germs, the vitality extra-heavy; The 5-6 of can in soil, surviving, by seed, muck, the propagation such as flowing water, germ is invaded from the root wound, also can invade on root hair top, grows in conduit, excretes poison, and the filling conduit causes that plant is dead.General occurrence factor is, hypsography low-lying, and impeded drainage, base fertilizer is not enough, and nitrogenous fertilizer is excessive, and broad irrigation waits between continuous cropping continuous cropping or the acid-base value 4-6 all can cause the disease generation or increase the weight of.At present in the world, there is not good medicament to administer this disease.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of watermelon and Muskmelon Fusarium wilt are had the biological bactericide composition of better control efficiency and the application on fusarium wilt thereof.
Biological bactericide composition of the present invention, its active ingredient is: amino-oligosaccharide and bacillus subtilis, amino-oligosaccharide weight content are 0.5～5%, the bacillus subtilis bacterial content is 1.0～1000.0 hundred million spore alive/grams.Biological bactericide composition of the present invention is wetting powder or the aqua that the conventional machining method is processed into.
Biological bactericide composition of the present invention is mainly used in preventing and treating watermelon or Muskmelon Fusarium wilt.
Biological bactericide composition of the present invention proves through field trial, and it has good control efficiency to watermelon and Muskmelon Fusarium wilt; Pass through simultaneously the composite of each active ingredient, can further improve preventive effect, preventive effect is significantly better than the single dose kind.
