The invention discloses a hot fogging concentrate containing pyraclostrobin and simeconazole, which is prepared from the following raw materials in percentage by weight: 1-15% of pyraclostrobin, 2-20% of simeconazole, 1-15% of surfactant and the balance of solvent. The hot fogging concentrate disclosed by the invention uses the combination of low-toxicity pyraclostrobin with favorable pathogenic bacteria inhibitory effect and simeconazole as an effective component, so that the product has high knockdown speed, has favorable effects on preventing and treating powdery mildew and downy mildew of cucumber, freckle and leaf spot of banana, and powdery mildew and anthracnose of rubber tree, and has outstanding effect on preventing and treating pathogenic bacteria.
Description
The application is the divisional application of " thermal fog of pyraclostrobin-containing and triazole bactericidal agent ", and the applying date of original application is on May 23rd, 2012, and application number is 201210162308.7, and denomination of invention is the thermal fog of pyraclostrobin-containing and triazole bactericidal agent.
Technical field
The present invention relates to technical field of pesticide, be specifically related to the thermal fog of a kind of pyraclostrobin-containing and triazole bactericidal agent.
Background technology
Thermal fog is a kind of pesticidal preparations newly developed in recent years, and it has without the need to being watered, availability is high, absorption affinity is strong, work efficiency is high, not easily produce the feature such as poisoning, be particularly suitable for drought and water-scarce area and orchard, booth, tall and big forest is as the use of bamboo grows etc.Existing thermal fog is as the patent of invention of publication number CN101322490, disclose difenoconazole heat fog agent of a kind of broad-spectrum sterilization and preparation method thereof, the raw material of this difenoconazole heat fog agent and consisting of: 1 ~ 40% Difenoconazole, 5 ~ 30% surfactants, 0.1 ~ 3% synergist, 0.01 ~ 2% stabilizing agent, surplus are solvent.This spray has good effect to diseases such as powdery mildew, scab, anthracnose, rust, leaf spots, but the active ingredient of this spray is only Difenoconazole (belonging to triazole bactericidal agent), although its fungicidal spectrum is wide, drug effect is higher, but due to the long-term single a large amount of use of this active ingredient, easily make germ create stronger resistance, be unfavorable for the further raising of drug effect, add the difficulty of bacteria-treating.And for example publication number is the patent of invention of CN102090410A, disclose a kind of nitrile bacterium azoles-Prochloraz thermal fog being active ingredient with nitrile bacterium azoles, Prochloraz, its raw material and consisting of: nitrile bacterium azoles 2.5 ~ 10 parts, Prochloraz 3 ~ 15 parts, cosolvent 0 ~ 20 part, solvent complements to 100 parts.This invention is composite by nitrile bacterium azoles and Prochloraz, combines the advantage of two series bactericidal agents, but its control only for anthracnose of rubber trees is better, and control efficiency reaches more than 89%.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of toxicity is low, thermal fog to the effective pyraclostrobin-containing of crop pest management and triazole bactericidal agent.
The thermal fog of pyraclostrobin-containing of the present invention and triazole bactericidal agent, be made up of the raw material of following weight percentage:
Wherein, triazole bactericidal agent is selected from any one in triazolone, simeconazoles, glyoxalin, penconazole, olefin conversion and bitertanol.
In the thermal fog of above-mentioned pyraclostrobin-containing and triazole bactericidal agent, the percentage by weight of each raw material is preferably:
In above technical scheme:
Described surfactant is for being selected from fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether (agriculture breast 600#), alkyl phenol formaldehyde resin polyoxyethylene ether (Nongru-700 #), alkylaryl polyoxyethylene polyoxypropylene ether, aliphatic alcohol polyoxyvinethene phosphate, alkylphenol polyoxyethylene phosphate, phenethyl phenol polyethenoxy ether phosphate, alkylaryl polyoxyethylene polyoxypropylene ether phosphate, one or more combination in castor oil polyoxyethylene ether and calcium dodecyl benzene sulfonate (agriculture breast 500#).When surfactant be chosen as the combination of wherein two or more material time, the proportioning between them can be any proportioning.
Described solvent is be selected from one or more the combination in polar solvent, aromatic hydrocarbon solvent and plant oil solvent.Wherein, described polar solvent can be one or more the combination be selected from acetophenone, phenmethylol, 1-METHYLPYRROLIDONE, DMF, DMA, hexanol and n-octyl alcohol; Described aromatic hydrocarbon solvent can be selected from one or more the combination in trimethylbenzene, o-dichlorohenzene, two wires oil, heavy oil and butylbenzene; Described plant oil solvent can be one or more the combination be selected from soybean oil, cottonseed oil, rapeseed oil, castor oil, turpentine oil or esterified vegetable oil; Wherein esterified vegetable oil is methyl oleate or ethyl oleate etc.When solvent be chosen as the combination of wherein two or more material time, the proportioning between them can be any proportioning.
Thermal fog of the present invention is prepared by existing common process, can be specifically: take raw material by proportioning, first solvent is dropped in reactor, open reactor agitator, drop into pyraclostrobin and triazole bactericidal agent, until completely dissolved (about 10 minutes) under agitation, then input table surface-active agent, then continue stirring 15 ~ 60 minutes, the oily product obtaining homogeneous transparent is thermal fog of the present invention.
As the pyraclostrobin of one of active ingredient, be pyraclostrobin again, chemical name: N-{2-[1-(4-chlorphenyl)-1H-pyrazole-3-yl oxygen methyl] phenyl } (N-methoxyl group) methyl carbamate, belong to methoxy acrylic bactericide, its maximum feature is that toxicity is low, to non-target organism safety, and to user and environment all safety close friends, be classified as " Candidate Agents reducing risk " by U.S. EPA.The mechanism of action of pyraclostrobin is the synthesis being stoped cell ATP by the electron transmission between pinning cytochrome b and C1, makes mitochondria can not produce and provide cell eubolism institute energy requirement to cause cell death; It can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete; very strong inhibitory action is had to the growth of spore germination and leaf intramatrical mycelium; have in protectiveness, therapeutic and local and inhale and osmotically active, the lasting period is long, resistance of rainwater washing against.Be widely used in preventing and treating the disease on wheat, paddy rice, peanut, grape, vegetables, potato, banana, lemon, coffee, fruit tree, walnut, tea tree, tobacco, ornamental plants, lawn and other field crops.
Thermal fog of the present invention is low and be active ingredient to the good pyraclostrobin of germ inhibition in conjunction with the triazole bactericidal agent of the wide above-mentioned selection of fungicidal spectrum with toxicity, makes products obtained therefrom knock down speed fast, to powdery mildew of cucumber, downy mildew; Banana freckle, leaf spot; Rubber tree powdery mildew, anthracnose etc. have good control efficiency.
