The consumption of effect composition is decreased, costs are reduced, the occurrence of the drug resistance of bacteria is retarded, and environment pollution is decreased.
Description
Technical field
The present invention relates to agriculture chemicals fungicide composition and application, be specifically related to prevent and treat microbicide compositions that contains propiconazol effective component and the application thereof that agricultural goes up the leaf spot of difficult control.
Background technology
At present, human attention to environmental problem, have higher requirement to the toxicity of agricultural chemicals and to environment, high malicious organophosphorous pesticide is because toxicity and environmental problem and be eliminated gradually. and the bactericide of having researched and developed many new and effective, low toxicities in recent decades is to replace high malicious organophosphorous pesticide, China's pesticide species and formulation are a lot, some causes severe contamination harm to ecotope, and the plant effective rate of utilization is low, the residue of pesticide time is long, easy-clear not again has defectives such as certain influence to the physical and mental health of numerous people.Propiconazole, english common name: propiconazole

Well-known propiconazole single variety has following effect:
Propiconazole is a kind of systemic fungicide with protection and therapeutic action; can be absorbed by root, stem, leaf portion; and can be soon in the plant body on conduction; propiconazole can be prevented and treated sac fungi, and the caused disease of basidiomycetes and imperfect fungus is particularly to root rotof flax; powdery mildew; bakanae disease of rice has the better prevention effect, but invalid to the oomycetes disease, and the propiconazole longevity of residure is about one month.
Press down mould azoles, English name: Imazalil Sulfate
Chemical name: 1～[2～(2,4～dichlorophenyl)～2～(2～propenyloxy group) ethyl]～1H～imidazoles
Structural formula:
Molecular formula: C

Pressing down mould azoles is interior absorption wide-spectrum bactericide, and this medicine influences cell permeability of the membrane, physiological function and lipid anabolism, thereby destroys the cell membrane of mould.The formation of mould fungus inhibition spore simultaneously.
Leaf spot: sigatoka is the disease that Jiao Qu generally takes place.Common have a sigatoka leaf spot disease, 3 kinds of the sick and coal line diseases of grey line.Sigatoka leaf spot disease scab oblong is to spindle-like, the edge pitchy, and middle part yellowish-brown, taupe be to canescence, the yellow haloing of the peripheral tool of spot, but several scab Colaesces are irregular patch.The sick pilosity of coal line is born in leaf margin, just is the oval foxiness, and the back enlarges and mutual Colaesce becomes patch, the existing dirty brown moire shape wheel of spot face line, and still visible original each single ash is brown to the canescence scab on it.Ash line disease also more starts from leaf margin, just also be oval brown stigma, after expand to the sharp protruding big spot of oblong in both ends or one end, spot middle part taupe is to grey, and the periphery brown is with yellow haloing outward, the existing concentric wheel stripe of spot face, more fine and close and distinct with the wheel line at proximal edge place especially.Influence the photosynthesis of plant when serious, cause irremediable disaster.
Go up the germ that produces resistance for control agricultural, a kind of way is to release new and new compositions existing kind five cross resistances.But the development cost height of new effective ingredient, the construction cycle is long, and all produces the speed of resistance forever less than insect.Dimension, identical for mechanism of action, the composition of different cultivars is mixed, and is a kind of selection of the best.If reasonable proportioning is arranged, usually can produce synergistic effect.Make field control effect significantly be better than the effect of two kinds of single agent.Show the result of 1+1＞2.
The bactericide that contains the single-activity component is prevented and treated the defective that often exists in various degree agricultural evil bacterium: such as using germ to be easy to generate pesticide resistance continuously, access times cause pollution to environment or the like more. and become bactericide can effectively overcome above shortcoming by the fungicide compounding of two kinds of active components. utilize two kinds of synergistic effects that active ingredient is mixed and is produced simultaneously, can improve preventive effect, reduce the effective ingredient consumption, save cost, delay the drug-fast generation of germ, and reduce pollution environment.
Summary of the invention
The purpose of this invention is to provide the microbicide compositions of preventing and treating sigatoka that a kind of cost is low, control efficiency is good.
Another object of the present invention provides the application of microbicide compositions.
In order to overcome the existing problem that effect of chemical control is poor, cost is high, technical scheme of the present invention is to solve like this: a kind of microbicide compositions that contains the effective ingredient of propiconazole, substantive distinguishing features that it is outstanding and obvious improvement are to press down mould azoles combination by A component propiconazole and B component, and microbicide compositions is A: B=50～1: 1～50 by mass ratio.
The application of a kind of claim 1 or 2 described microbicide compositions, also include auxiliary material when its composition is composite, its auxiliary material refers to emulsifier, dispersant, auxiliary agent, defoamer, antifreezing agent, thickener, can be made into emulsifiable concentrate, aqueous emulsion, suspending agent when A component, B component and after auxiliary material mixes, get in the auxiliary material when composite that wherein two or more uses simultaneously, but be not limited to above-mentioned formulation.
Wherein emulsifier comprises, calcium dodecyl benzene sulfonate, aliphatic alcohol polyoxyvinethene phosphate, alkylphenol polyoxyethylene phosphate, phenethyl phenol polyethenoxy ether, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, castor oil polyoxyethylene ether;
