Technical field
The invention belongs to plant disease-resistant viral disease field, and in particular to a kind of anti-plant viral disease combination containing lentinan
Thing.
Background technology
The compound A of the structure containing acylhydrazone is a kind of pesticide activity composition, and its chemical name is:(1S, 3S)-N- (4- chlorobenzenes
Methylene) -1- methyl -2,3,4,9- tetrahydropyridines are simultaneously【3,4-b】Indoles -3- formylhydrazines.The compound A of this structure containing acylhydrazone
There is extraordinary bioactivity to tobacco mosaic virus (TMV), TOMV etc., at the same such compound be easily absorbed by plants,
It is degradable in the environment, have good Environmental compatibility.
Compound A structure formula：
Lentinan (English name：Lentinan), lentinan is the effective work extracted from quality xianggu fructification
Property composition, the main component of mushroom is polysaccharide and unrighted acid, also containing the ergot that can be largely changed into vitamin D
Sterol and fungisterol, the lentinan through hot water extraction can adjust the T cell activity for having immunologic function in human body, can reduce methyl
The ability of cholanthrene induced tumor.Mushroom has strong inhibitory action to cancer cell.Mushroom also contains double stranded RNA, can induce
Interferon is produced, there is anti-virus ability.
Virus disease is the Major Diseases of the industrial crops such as tobacco, tomato, rice and capsicum, gives vegetable cultivation and cigarette every year
Grass production causes serious loss.In the chemical control of plant virus, years of researches have been carried out both at home and abroad, although one
A little viral agents come into practical stage, but still have the shortcomings of resistance is low, cost is high, drug effect is low, high poison, far not
Agricultural sustainable development requirement can be met, so development of new, efficient agricultural chemicals turn into the key of preventing and treating virus.
Have some applications of the patent containing lentinan in terms of tobacco disease resistance viral disease at present.Such as lentinan and rape
Plain lactone (proprietary term a kind of antiviral composition and its application containing lentinan and brassin lactones, number of patent application：
201110027898.4), lentinan and sodium sulphate (proprietary term：A kind of antiviral composition containing lentinan, patent application

Medicine, number of patent application：201010294324.2) patent such as, but lentinan is not sent out also at present with compound A combinations thing
The existing application being reported on tobacco disease resistance poison, compound A belong to natural products banisterine and harmine bases chemical combination
Thing, there is induction crop to produce premunition, suppress the effect of virus infection, reach antiviral with lentinan compounding, increase and produce
Amount and the effect for improving quality.
It is an object of the invention to the combination by lentinan and compound A, the crop virus such as preventing and treating tobacco, tomato
Disease, particularly to by tobacco mosaic virus (tmv) (TMV), tobacco cucumber mosaic virus sick (CMV), tobacco potato Y virus disease
(PVY) virosis of initiation such as, there is good prevention effect.Said composition can induce crop to produce premunition, suppress virus
Infect, while have the function that it is antiviral, increase yield and improve quality.

In order to improve the activity of composition pesticide of the present invention, while it is easy to store and transports, is needed in the bactericidal composition
Add suitable auxiliary agent and be prepared into conventional any formulations of pesticide, the species and dosage of auxiliary agent can match somebody with somebody according to bactericidal composition
The conventional dosage of the dosage form selection of system, this is known to those skilled in the art.
Being more highly preferred to proportioning is, compound A or its salt：0.5%~60%, lentinan：0.5%~60%, solvent：
10%~80%, emulsifying agent：5~10%, stabilizer：3~10%.
Described compound A salt can for compound A benzoate, oxalates, citrate, hydrochloride, sulfate,
Phosphate.
Its of the invention processing method is by lentinan, compound A or its salt or its mixture, auxiliary agent by known method
Stirring and dissolving is sufficiently mixed to form.
Solvent is water, benzene,toluene,xylene, methanol, ethanol, n-butanol, acetic acid, ethyl acetate, hexane, dimethyl methyl
One or more in acid amides, dimethyl sulfoxide (DMSO)；
Stabilizer is one kind in citrate, citric acid, hydrochloric acid, sulfuric acid, phosphoric acid, potassium dihydrogen phosphate, sodium tripolyphosphate
With it is several；
Emulsifying agent is AEO, alkylbenzenesulfonate, castor oil polyoxyethylene ether, alkylphenol-polyethenoxy
Ether, polyethylene glycol, alkylphenol-polyethenoxy polyethenoxy ether, EO-PO block compounds, polyoxyethylene sorbitan carboxylic ester
One or more in the emulsifying agent Deng known to.
In the present invention, other auxiliary agents, such as bleeding agent, synergist can also be contained if desired, they are ability
Well known to field technique personnel.
The beneficial effects of the invention are as follows：Composition pesticide of the present invention can be used for preventing and treating various crop virus, such as tobacco
Leaf disease viral disease, Tomato yellow mosaic virus, maize dwarf mosaic virus disease, rice dead leaf disease etc., induction crop produce premunition, suppressed
Virus infects, and has the function that antiviral, increase yield and improves quality.
