Description
Technical field
The invention belongs to pesticides application technical field, and in particular to a kind of Synergistic sterilizing combination of preventing and treating sclerotinia sclerotiorum
Thing.
Background technology
Rape is the main oil crops of China, and sclerotinia sclerotiorum is one of important disease in Rape-seed production, long-term strain
The incidence of disease is up to 10%~30%, serious up to more than 80%；The general underproduction 10%~70% of diseased plant.Whole breeding time can be sent out
Disease, productive phase, occurs most heavy.Stem, leaf, flower, silique can be aggrieved, and stem is aggrieved most heavy.At present, because long-term single use is killed
Bacterium medicament so that pathogen is easy to develop immunity to drugs, causes drug effect to decline, disease breaks out, and then increases medication, is formed pernicious
Circulation, increases drug cost, aggravates environmental pollution, this is also a great problem of chemical prevention.Therefore by the different mechanisms of action
Rationally compounding is to overcome one of effective measures of resistance to the action of a drug generation to agricultural chemicals.
Fluorine azoles bacterium aniline, English name：Penflufen.Fluorine azoles bacterium aniline is class novel pyrazole developed in recent years
Acid amide fungicides, with the effect such as protection, treatment, interior suction, transporting.The bactericide is succinate dehydrogenase (SDH) inhibitor,
Respiratory chain electron transmission Complex II is mainly acted on, energetic supersession is blocked.Seed after treatment can in germination process
To absorb fluorine azoles bacterium aniline, and other positions of plant are transmitted to by xylem, so as to play a part of cover crop.Can
With prevent and treat kind pass, soil pass basidiomycetes and sac fungus disease, to have black scurf of potato caused by rhizoctonia and ustilagin etc.,
The diseases such as wheat sharp eyespot, rice sheath blight disease, sclerotinia sclerotiorum, loose smut of wheat, the bunt of wheat, corn southern leaf blight have
There are good prevention and control, therapeutic effect.
Ningnanmycin, is called Junkeduke, English common name ningnanmycin is that Cystosine nucleocide type of new generation resists
Raw element class wide-spectrum bactericide.Ningnanmycin is Chengdu Inst. of Biology, Chinese Academy of Sciences after the Seventh Five-Year Plan, 85,95 national science and technologies
The patented technology product tackled key problems and succeeded in developing, this bacterium is isolated in Ningnan County, Sichuan Province soil, is found first
Cystosine nucleocide type antibiotics, therefore its tunning is named as Ningnanmycin.At present in tobacco mosaic virus disease, tomato
Virosis, pepper virus disease, rice seedling blight, root rot, stripe disease, alternaria leaf spot of apple, cucumber are white
Registration is achieved in powder disease, sclerotinia sclerotiorum, peronophythora litchi is being prevented and treated in addition, it is other crop virosis, stem rot, climing withered
Also it has been widely applied in the multiple diseases such as disease.
At present the research of sclerotinia sclerotiorum is applied to using Ningnanmycin, fluorine azoles bacterium aniline as the composition of active ingredient not yet
There is relevant report.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high-efficiency low-toxicity, environmentally friendly, preventing and treating sclerotinia sclerotiorum
Synergistic bactericidal composition.
The present invention is to be achieved through the following technical solutions：A kind of Synergistic bactericidal composition for preventing and treating sclerotinia sclerotiorum, effectively
Composition is made up of Ningnanmycin and fluorine azoles bacterium aniline, and the weight ratio of Ningnanmycin and fluorine azoles bacterium aniline is 15-1:1-10.It is preferred that
The weight ratio of ground, Ningnanmycin and fluorine azoles bacterium aniline is 5-1:1-5.
The active ingredient of the Synergistic bactericidal composition accounts for the 5-50% of Synergistic bactericidal composition gross weight, and surplus is agricultural chemicals
Upper acceptable auxiliary agent.
Described Synergistic bactericidal composition is according to method known in those skilled in the art, and adding can connect on corresponding agricultural chemicals
The formulation that the auxiliary agent received is made is wettable powder, water dispersible granules or suspending agent.
The auxiliary agent that uses of Synergistic bactericidal composition of the present invention includes dispersant, wetting agent, binding agent, disintegrant, antifreeze
Agent, defoamer, thickener, filler, solvent etc. or it is other be beneficial to active ingredient in the formulation stablize and drug effect play it is known
Material, is all the various auxiliary components commonly used in field of pesticide preparation or allow to use.
The dispersant and wetting agent are selected from calcium dodecyl benzene sulfonate, lauryl sodium sulfate, Tea Saponin, polycarboxylic acids
Salt, lignosulfonates, APES, the formaldehyde condensation products of methyl naphthalene sulfonic acid sodium, sodium hydroxyethyl cellulose, alkyl
Sodium naphthalene sulfonate, aliphatic alcohol polyoxyvinethene phosphate, AEO, sodium butylnaphthalenesulfonate, styrylphenol gather
One or more in oxygen vinethene, sldium lauryl sulfate, pull open powder.
The one kind of the binding agent in starch, polyvinyl alcohol, sodium carboxymethylcellulose.
The one kind of the disintegrant in sodium carbonate, calcium chloride, ammonium carbonate, potassium chloride, sodium sulphate.
The one kind of the antifreezing agent in ethylene glycol, propane diols, glycerine, urea.
The defoamer is selected from organic silicone oil.
The one kind of the thickener in xanthans, Arabic gum, Magnesiumaluminumsilicate.
The filler is in kaolin, precipitated calcium carbonate, attapulgite, soil powder, diatomite, bentonite, white carbon
One or more.
The solvent is deionized water.
Beneficial effects of the present invention：The present invention carries out the Synergistic sterilizing of rational mixture by Ningnanmycin and fluorine azoles bacterium aniline
Composition is used to prevent and treat sclerotinia sclerotiorum, and substantially, preventive effect is significantly higher than alone Ningnanmycin and fluorine azoles bacterium benzene to synergistic function
The preventive effect of amine, so as to reduce Pesticide use amount, delays disease to develop immunity to drugs, and the lasting period is long, environmentally friendly.
Embodiment
Technical scheme and technique effect are described further below in conjunction with specific embodiment, institute of the present invention
The percentage stated is weight percentage.
First, Toxicity Determination is tested
After determining the effective inhibition concentration scope of each medicament through prerun, each medicament is set 5 agent by active constituent content respectively
Gradient processing is measured, if clear water is compareed.Reference《Farm-chemical indoor determination test rule bactericide》Carry out, using mycelial growth speed
Rate method determines virulence of the medicament to Sclerotinia sclerotiorum.Colony diameter is measured with crossing method after 72h, each processing is calculated net raw
Long amount, mycelial growth inhibition rate.
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm value (x), with minimum
Square law tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.Simultaneously according to the abundant methods of Sun Yun
Co-toxicity coefficient method (CTC) evaluate the synergistic effect of pharmacy mix, i.e. CTC≤80, composition shows as antagonism, when 80
<CTC<120, composition shows as summation action, and when CTC >=120, composition shows as synergistic effect.As a result such as table 1.
