Description
Technical field
The invention belongs to pesticides application technical fields, are related to a kind of composition pesticide, are applied to prevention and treatment tobacco gray mold.
Background technique
Tobacco is the raw material of cigarette industry, is the major economic crops in China, occupies an important position in national economy.
Tobacco gray mold (Tobacco grey mold) is the very strong disease of harmfulness on tobacco leaf production, and pathogenic bacteria are Botrytis cinerea
(Botrytis cinerea), host range is wide and harmfulness it is strong, the disease floating seedlings to flue-cured tobacco entire breeding time all
There is generation, up to 100%, morbidity leaf rate generally 10%~20%, serious reachable 80% or more, typically results in diseased plant rate
Yield of tobacco and quality decline, cause serious financial consequences to tobacco grower.
The change of expansion, crop allocation and cropping system with China's tobacco intensive manufacture scale etc., tobacco diseases
Generation it is in rising trend.For a long time, tobacco gray mold always is one of main limiting factor in tobacco leaf production, chemistry
Prevention and treatment is always to control the most important means of tobacco gray mold, but the long-term single use of these chemical agents generates pathogen
Serious resistance, so have increasing need for safe and efficient chemical agent.
Iprodione is dicarboximide class fungicide, inhibits protein kinase synthesis, controls the intracellular of many cell functions
Signal, it both can inhibit fungus spore germination and generation, also can inhibit mycelia growth to the ontogeny in the pathogen history of life
Stage has an impact.Iprodione wide sterilization spectrum, main controlling object be Botrytis, Monilia, Penicillium, Sclerotinia,
Various crop disease caused by Alternaria, Helminthosporium, Rhizoctonia, Phoma, mycosphaerella, Cercospora etc..
Tebuconazole category triazole bactericidal agent is a kind of systemic fungicide with protection and therapeutic effect, is ergot steroid
Alcohol synthetic inhibitor, has that absorbability is strong, drug effect is high, safety, lasting period are long to crop.Have to tobacco gray mold anti-well
Control effect.But due to long-time service of the triazole type medicament on tobacco, pathogen is caused to produce resistance, agricultural chemical residue in tobacco is super
Mark problem is serious.
Pyrroloquinoline quinone (Pyrroloquinoline quinine, PQQ) is a kind of brownish red, tasteless, thermostabilization, water
Soluble organism was found in bacterium in 1979, is widely present in animal and plant body, was the prothetic group of a variety of important enzymes,
It can influence the level of respiratory chain function and interior free yl.Existing Chinese patent CN201210506724.4 is green withered in PQQ prevention and treatment
Disease has been introduced, but there is presently no correlative studys in terms of combining bactericidal agent for preventing and treating tobacco gray mold.
Summary of the invention
In view of the deficienciess of the prior art, the object of the present invention is to provide a kind of iprodiones with synergistic effect, penta
The pesticide complex composition of the pure and mild pyrroloquinoline quinone of azoles ensures the yield and quality of tobacco for preventing and treating tobacco gray mold.
The present invention is realized by following measures:
A kind of composition pesticide for preventing and treating gray mold, including iprodione, Tebuconazole, pyrroloquinoline quinone and insecticides adjuvant,
The weight ratio of the iprodione and Tebuconazole is 1~6:1~6.
Further, the weight ratio of the iprodione and Tebuconazole is 1:4 or 1:5.In some embodiments of the invention,
The present invention provides one kind comprising iprodione and Tebuconazole as effective active composition composition, wherein iprodione and Tebuconazole
Weight ratio is 1:1,1:2,1:4,1:5,2:3.By field control effectiveness test, these compositions are compared with iprodione and Tebuconazole single dose pair
Tobacco gray mold can generate synergistic function, and pyrroloquinoline quinone, which is added, can be enhanced effect, and a small amount of medicament can produce
Raw better control efficiency.
Further, the iprodione and tebuconazole weight summation account for composition weight percent content be 25~
40%.
Further, the pyrroloquinoline quinone accounts for the 1-5wt% of composition pesticide.
Further, the auxiliary agent is wetting agent, dispersing agent, one of emulsifier, thickener, antifreezing agent and defoaming agent
Or it is a variety of.
Iprodione, Tebuconazole and pyrroloquinoline quinone, which are matched for effective active composition with auxiliary agent, can be made into times allowed on pesticide
It anticipates a kind of dosage form.
Further, the dosage form is in the dosage forms such as suspending agent, aqueous emulsion, wettable powder, microemulsion, water dispersible granules
One kind, preferred suspending agent.
It is a kind of prevent and treat gray mold composition pesticide be mainly used in prevention and treatment tobacco gray mold.
The method of the prevention and treatment tobacco gray mold is that (1) Seedling Stage sprays, wherein pyrroloquinoline quinone accounting 5wt%, (2)
Squaring period sprays, wherein pyrroloquinoline quinone accounting 2wt%.Seedling Stage and squaring period are all gray mold onset peak periods, at this
Two periods are prevented and treated, and quality of tobacco can be significantly improved, and disease incidence are reduced, after Seedling Stage sprays, since composition is good
Drug effect enhance the resistance of tobacco seedlings while killing germ, whole quality of tobacco can be improved,
Further, the wetting agent includes dialkyl succinylsuccinate sulfonate, sulfosuccinic acid monooctyl ester sodium salt, alkyl naphthalene sulfonic acid
Salt, fatty alcohol polyoxyethylene ether, alkyl phenol polyoxyethylene ether, dioctyl sodium sulphosuccinate, alcohol ethoxylate, alkyl
One of phenol ethoxylate, octadecyl sodium sulfosuccinate or multiple combinations.
Fatty acid polyethylene glycol ester, nonylphenol polyoxyethylene ether, polyvinyl alcohol, lignin sulfonic acid can be used in the dispersing agent
Sodium, sodium metnylene bis-naphthalene sulfonate, naphthalenesulfonic acid-formaldehyde condensate, sodium methylene bis-naphthalene sulfonate, to methoxyl group fatty acyl amido benzene
One of sodium sulfonate, three phenethyl phenol polyoxyethylene ether phosphates or multiple combinations.
Lauryl sodium sulfate, styrylphenol polyoxyethylene ether, alkylphenol-polyethenoxy can be used in the emulsifier
Ether polyethenoxy ether, epoxidized soybean oil, phenethyl phenol polyethenoxy ether, calcium dodecyl benzene sulfonate, phenethyl phenol polyoxy second
One of alkene polyethenoxy ether or multiple combinations.
Polyacrylate, methylcellulose, sorbierite, aluminum magnesium silicate, xanthan gum, Arab can be used in the thickener
Organic silicon, mineral oils, alcohols, fatty acid and aliphatic ester can be used in the one or more combinations of glue, white carbon black, defoaming agent
Class, imines, amides, phosphoric acid ester, polyethers, Siloxane-Oxyalkylene Copolymers class or polyoxyethylene-polyoxypropylene mixture
One of or multiple combinations.
The defoaming agent includes organic silicon, alcohols, fatty acid and fatty acid ester, imines, amides, phosphate
Class, polyethers etc., antifreezing agent use one of ethylene glycol, isopropanol, glycerol or multiple combinations.
Compared with prior art, beneficial effects of the present invention: (1) since the mechanism of action of combination agent is different, in addition to killing
Pathogen, the resistance that pathogen can also be delayed well to generate medicament；(2) compared with single dose, the composition pesticide is to ash
Mildew has apparent synergistic function, hence it is evident that improves control efficiency；(3) compared with single dose, the amount ratio list of the composition
The dosage of only reactive compound substantially reduces, and the preventive effect of mixture is greater than the preventive effect of independent component, has saved drug cost；(4)
The pyrroloquinoline quinone added in combination agent, which can be used as plant growth regulator, influences each stage of plant growth and development, can show
The resistance for writing enhancing tobacco, improves the quality of tobacco.
