Abstract
The invention relates to a compound emulsion in water of chitosan oligosaccharide and validamycin A. Effective ingredients in the compound emulsion in water are chitosan oligosaccharide and validamycin A. The compound emulsion in water is obtained through a conventional preparation process. The composition has good preventing and treating effects on rice sheath blight disease. Since the active polysaccharides resistance induction and the fungicidal activity of the validamycin A have synergism effect, the effect of preventing and treating the rice sheath blight disease is effectively enhanced, the obvious preventing and treating effect can be achieved in earlier stage or later period of pathogenesis, and the pharmacy suitable period is long.
Description
Technical field
The present invention relates to the composite aqueous emulsion of a kind of chitosan oligosaccharide and jinggangmycin A, be specifically related to the composite aqueous emulsion of a kind of chitosan oligosaccharide for the water prevention rice sheath blight and jinggangmycin A, belong to field of biological pesticide.
Background technology
Fungi is that a class trophosome is generally filamentous, tool cell wall, the eucaryote bred in spore-bearing mode.Fungal species is many, and distribution is wide, and may reside in water and soil and on various objects on the ground, most of fungi is saprophytic, minority symbiosis and parasitism.
Rice sheath blight disease is mainly survived the winter in soil with sclerotium, and the sclerotial germination of the floating water surface of Second Year extracts mycelia out, invades leaf sheath and forms scab, forms new scab from scab growing again mycelia to neighbouring spreading.Fall into the water when sclerotium and current can be borrowed to propagate.Temperature 28-32 DEG C and relative moisture are more than 97% be conducive to plant disease epidemic.Excessive nitrogen fertilizer application, high dense planting, poured water and deeply too much or was partially late the principal element of bringing out disease.Paddy rice falls ill from tillering stage, reaches onset peak around booting stage, and after milk ripe stage, the state of an illness declines.The symptom of disease is for generally starting morbidity in tillering stage, and on leaf sheath, occur water stain shape elliptical spot at approximately level at first, later scab increases, and normal healing mutually becomes the moire shape spot of irregular large shape, and its edge is brown, middle part celadon or filbert.Symptom on blade is substantially identical with on leaf sheath.Disease is expanded from bottom to top, can expand to sword-like leave time serious, even causes fringe portion to fall ill, large stretch of lodging.
Chitosan oligosaccharide and Chitosan poly oligosaccharide, also claim chitin oligo saccharide, formal name used at school β-Isosorbide-5-Nitrae-oligosaccharides-gucosamine, and being a kind of product obtained through special biological enzyme technology process by shitosan, is a kind of good water solubility, and function is large, the low molecular weight product that biologically active is high.Chitosan oligosaccharide, by being adsorbed on bacterial cell surface, forming one deck polymeric membrane, thus plays restraining and sterilizing bacteria effect; Another kind of mechanism is that chitosan oligosaccharide passes through to penetrate in bacterial cell body, the cytoplasm with anion in cyton is flocculated, upsets the normal physiological activity of cell, thus kill bacteria.In general, molecular weight is larger, and the outer membrane formed is finer and close, nutriment more can be stoped to enter bacterial cell, thus antibacterial action successful; Molecular weight is less, more easily enters in the gap structure of cell wall, thus the metabolism of interference cell, bactericidal action is obvious.Chitosan oligosaccharide itself, containing abundant carbon and nitrogen, can be decomposed by the microorganisms and to utilize and as the nutrient of plant growth, chitosan oligosaccharide can promote that beneficial microorganism grows and suppresses some phytopathogens.Chitosan oligosaccharide also can stimulating plant growth and the disease resistance of inducing plant, has direct repression to a certain degree to various plants pathogen.
Jinggangmeisu comprises jinggangmycin A and jinggangmeisu (mixture of jinggangmycin A and its isomer B, C, D, E, F), at present by the single dose of national agriculture chemical registration, is mainly used in control crop banded sclerotial blight.Its compound formulation includes, composite with waxy Bacillus, for preventing and treating banded sclerotial blight, rice blast, head blight; Composite with carbendazim, for preventing and treating banded sclerotial blight, rice blast, head blight; Composite with tricyclazole, for preventing and treating banded sclerotial blight, rice blast, false smut; Composite with carbendazim, for preventing and treating rice blast, false smut; With olefin conversion or ucleosides antibiotic composite, for preventing and treating banded sclerotial blight, false smut; With own azoles alcohol or oxyenadenine composite, for preventing and treating banded sclerotial blight; Composite with bacillus subtilis, for preventing and treating false smut.Jinggangmeisu is to people and animals' low toxicity, and to birds fish safety, absorption farm antibiotics series bactericidal agent in belonging to, by disturbing and suppressing pathogen cell normal growth to be grown, plays therapeutic action.
In prior art, the usage amount of agricultural chemicals is increasing, not only makes crop produce resistance, also brings serious pollution to environment, for the problems referred to above, the invention provides the composite aqueous emulsion of a kind of chitosan oligosaccharide and jinggangmycin A.
Technical scheme of the present invention is as follows:
A composite aqueous emulsion for chitosan oligosaccharide and jinggangmycin A, active ingredient is chitosan oligosaccharide and jinggangmycin A.In the present invention, active ingredient content is by mass percentage 0.5%-3% chitosan oligosaccharide and 2%-30% jinggangmycin A; Preferably, active ingredient content is by mass percentage 0.5%-2.5% chitosan oligosaccharide and 2%-25% jinggangmycin A; Preferred, active ingredient content is by mass percentage 0.5%-1% chitosan oligosaccharide and 2%-15% jinggangmycin A; Most preferred, active ingredient content is by mass percentage 1.5% chitosan oligosaccharide and 15% jinggangmycin A.
Further, composite aqueous emulsion of the present invention, emulsifier is selected from Nonyl pheno (E0=10) ether phosphate, triphenoethyl benzene phenol polyethenoxy ether phosphate (agriculture breast 600# phosphate), Nongru-700 #, agriculture breast 2201#, Span-60#, emulsifier T-60, TX-10, agriculture breast 1601#, agriculture breast 600#, agriculture breast 400#; Solvent is selected from dimethylbenzene, toluene, cyclohexanone, solvent naphtha (trade mark is S-150, S-180, S-200); Stabilizing agent is selected from triphenyl phosphite, epoxychloropropane, aceticanhydride; Antifreezing agent is selected from ethylene glycol, propane diols, glycerine, urea, inorganic salts as sodium chloride; Thickener is selected from xanthans, polyvinyl alcohol, bentonite, aluminium-magnesium silicate; Preservative is selected from methyl alcohol, benzoic acid, Sodium Benzoate.
The present composition has extraordinary control efficiency to rice sheath blight disease, the present invention utilizes the bactericidal activity of active polysaccharide induction of resistance and jinggangmycin A to have the collaborative effect be added, effectively enhance effect rice sheath blight disease being had concurrently to prevention and therapy, morbidity early stage or morbidity later stage all can reach control efficiency significantly, and medication optimum period is long.
