Description
Technical field
The present invention relates to a kind of anti-plant virus agent, relate in particular to a kind of efficiently, plant resource anti-plant virus agent and its production and application cheaply.
Background technology
Viral diseases of plants has become the second largest class plant disease that is only second to fungal diseases of plants.Because virus obligate parasitism in plant cell, it duplicates required material, energy and place and relies on the host fully, and plant does not have complete immune metabolic system, make that the control of the viroses of plant is comparatively difficult, cause enormous economic loss to agricultural production, about 20,000,000,000 dollars of the loss that is caused by plant virus in whole world every year, the loss that the annual only tobacco mosaic virus in the whole world causes just reaches more than 100,000,000 dollar.
For the effectively harm of controlling plant virus; the agri-scientific research personnel are cross protection except taking traditional antiviral breeding, attenuated strain, improve the methods such as culture technique, insecticide control biography virus mediator and transgenosis; also study the chemical prevention and control method of viral diseases of plants, and carried out the research work of the natural anti-plant virus agent of screening from plant.Natural component in the plant have structure uniqueness, function different and with characteristics such as environmentally compatible, make and from plant, seek the focus that antiviral substance has become people's research and development.Up to now, had been found that the various plants extract is inhibited to plant virus, but up to the present, had only the sub-fraction anti-plant virus agent to obtain practical application.
No. 00106234.4 patent disclosure of Chinese patent Cynanchun komarovii extract and application thereof.Active constituent with resisting tobacco mosaic virus disease in the ethanol extract of the acrial part of Cynanchun komarovii is luxuriant and rich with fragrance parallel indoles Li Xiding Alkaloid, wherein the 7-demethoxytylophorine is its main active constituent, and its specific activity is high 1～2 order of magnitude of preparation of widely used resisting tobacco mosaic disease in the market.The present invention can be applicable to the control of the control of the viroses of plant, particularly tobacco mosaic.
No. 200510044113.2 patent disclosure of Chinese patent tree-of-heaven antiviral agents and manufacture method thereof.Root skin with the quassia tree-of-heaven is a raw material, through pulverizing, extraction, suction filtration, processing technology such as concentrate and obtain heaven tree extract.Add solvent and emulsifier again and be mixed with Antiphytoviral missible oil.Product raw material source is wide, development cost is low; Processing technology is simple; Safe, environmentally safe waits advantages such as non-target organism safety to people and animals.
Above technical products exists following defective and deficiency: the function that does not have control aphis propagation virus disease; Single to the plant virus mode of action, have only prevention effect, do not have obvious result of treatment, can not improve the plant disease-resistant ability; Product wettability, plate-out ability, poor permeability, unit are deposition amount of liquid medicine is few, thereby influences drug effect; The use cost height, the production process complexity.
Summary of the invention
The present invention has overcome the deficiency of prior art products, providing a kind of can reduce by the aphis propagation virus disease, the viroses of plant had fine result of treatment, can obviously improve the plant disease-resistant ability, wettability, plate-out ability, good penetrability, use cost is low, the simple a kind of anti-plant virus agent of production process, relate in particular to a kind of efficiently, plant resource anti-plant virus agent and its production and application cheaply.
For solving the problems of the technologies described above, anti-plant virus agent of the present invention, calculate with weight ratio, cream paulownia seed oil cake extract by 10～50 parts, 10～50 parts alkaloid, 10～50 parts fulvic acid salt, 5～50 parts plant growth regulator, 10～60 parts surfactant, 20～75 parts solvent composition.This method may further comprise the steps;
1) cream paulownia seed oil cake is pulverized, making its particle diameter is that 10～40 orders are stand-by;
2) cream paulownia seed oil cake extract preparation: the cream paulownia seed oil cake that crushes is packed in the reactor, employing ethanol is extractant, press material: the weight ratio of solvent=1: 2～1: 20 adds in the material, be under 50～90 ℃ the condition in extraction temperature, extracted 30～120 minutes, Separation of Solid and Liquid makes cream paulownia seed oil cake extract behind precipitation;
3) dissolving: respectively alkaloid, plant growth regulator, solvent, cream paulownia seed oil cake extract, surfactant are added in the reactor, the control solution temperature is 50～80 ℃, and the stirring and dissolving time is 20～90 minutes;
4) disperse: fulvic acid salt is added in the reactor, and the control dispersion temperature is 50～65 ℃, and the dispersed with stirring time is 20～90 minutes;
5) moulding: after cooling, make anti-plant virus agent.
Above-mentioned alkaloid can be any one or more mixing in following: matrine, oxymatrine, sophocarpine, N-Oxysophocarpine, sophoramine, Sophoridine.
Above-mentioned fulvic acid salt can be any one or more mixing in following: sodium fulvic acid, fulvic acid potassium, fulvic acid zinc, copper fulvate, fulvic acid manganese.
Above-mentioned plant growth regulator can be any one or more mixing in following: DCPTA, bright amine fat, abscisic acid, compound sodium nitrophenolate, nucleotide, Nafusaku, o-nitrophenol potassium, p-nitrophenol potassium.
Above-mentioned surfactant can be any one or more mixing in following: fatty alcohol-polyoxyethylene ether, higher fatty acid salt, dodecyl benzene sulfonate, naphthenate, sodium metnylene bis-naphthalene sulfonate, lignin benzene sulfonate, Tea Saponin.
Above-mentioned solvent can be any one or more mixing in following: water, dimethyl sulfoxide (DMSO), ethanol.
Above-mentioned anti-plant virus agent is as the application of resisting against plant mosaic virus disease.Behind 500～2000 times of liquid of its using method dilute with water, spray in the mode of spraying.
Beneficial effect of the present invention: cream paulownia seed oil cake extract and alkaloid have very strong biologically active to plant virus in the product, alkaloid has very strong insecticidal function to aphid, can effectively control the quantity of aphid, thereby reduce chance by the aphis propagation virus disease; Result of treatment: the initial stage of catching an illness is the energy normal growth after anti-plant virus agent is handled, and scab obviously disappears, and the continued growth of plant energy, reduces production loss, reduces peasant's economic loss; Plant growth regulator, fulvic acid salt can stimulate plant growth, inducing plant cylinder accumulation phenols precursor substance, behind a series of biochemical reactions, can form plant defendance element and lignin, with enhancing crop disease-resistant ability, thus the control efficiency of reinforcement antiviral activity composition; Product has remarkable wettability, plate-out ability, good penetrability.Superpower wettability can make soup diffusion when spraying, and medicine is enlarged markedly at the spreading area of crop surface, can significantly improve the soup availability; Plate-out ability that it is remarkable and permeability enter in the plant corpus medicine in a large number, and drug effect is given full play to; Anti-plant virus agent of the present invention is because efficient, low-cost, and this has opened up new technological approaches and method for screening from cream paulownia discarded object prevents and treats the viroses of plant, thereby China's raising cream paulownia waste material utilization ratio and energy-saving and emission-reduction are made new contribution.
