Description
Technical field
The invention belongs to technical field of pesticide, relate to the preparation and the application of the bactericidal composition of a kind of pyraclostrobin-containing and thiocarbamates.
Technical background
Pyraclostrobin (pyraclostrobin), molecular formula: C

2, chemical name: methyl (N)-[[[1-(4-chlorobenzene) pyrazoles-3 base)-oxygen]-the 0-methoxyl group]-the N-methoxymethyl carbamate.
Pyraclostrobin is the bactericide of BASF AG's latest model methoxy acrylic.Pure article are that white is to the tasteless crystalline solid of oldlace.The mechanism of action is the mitochondrial respiratory inhibitor.Make mitochondria can not produce and provide cell eubolism institute energy requirement, finally cause cell death.It can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete.Growth to spore germination and leaf intramatrical mycelium has very strong inhibitory action, has protection and therapeutic activity.Have permeability and local systemic activity, 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 and ornamental plants, lawn and other field crops.This compound not only toxicity is low, to non-target organism safety, and also all friendly safely to user and environment, classified as " the candidate's medicament that reduces risk " by U.S. EPA.In addition, pyraclostrobin can be to making the positive physiological regulatory action of deposits yields, and the generation of its ability ethene suppressing can help crop to have longer time deposit bio-energy to guarantee maturity like this; Can significantly improve the activity of the restore nitrification enzyme of crop, mean the use that can reduce nitrogenous fertilizer in the soil, thereby further reduce phreatic influence; When crop received viral attack, it can quicken to resist the formation of albumen---and identical with crop self salicylic acid synthetic to the synthesis of degeneration-resistant albumen.Pyraclostrobin is the efficient mitochondrial respiratory inhibitor after improving on the kresoxim-methyl basis, is to have replaced the o-methyl-phenyl-in the kresoxim-methyl molecular structure with N-rubigan pyrazolyl, and the another methoxy acrylic wide-spectrum bactericide of exploitation.Its activity is higher, is present 3 times with series bactericidal agent.And the report that kresoxim-methyl just takes place relevant for the wheat powdery mildew resistance after 1 year in practical application, to 2000 the resistance spore (2%-99%) in the north of Germany, the existing a large amount of reports in the north and Britain of France.Descend to the preventive effect of powdery mildew is existing at present at home.
Propineb (propineb), molecular formula are (C

4Zn) x, chemical name: acrylic bisdithiocarbamic zinc.
Propineb acts on the synthetic of fungal cell wall and protein, can suppress infecting and sprouting of spore, can suppress mycelial growth simultaneously, causes its distortion, death.And this medicine contains the zinc element that is easy to by the crop absorption, helps promoting plant growth and the quality that improves fruit.
Zineb (zineb), molecular formula are C

4Zn, chemical name: zinc ethylenebisdithiocarbamate.
Zineb belongs to the benzene thiocarbamates; It is the protectant that a kind of foliage spray is used; To plant safety; The active ingredient chemical property is more active, in water, is prone to be oxidized to different thiocyanation compound, to the cause of disease thalline contain-enzyme of SH base has had strong inhibitory effects; And the direct kill pathogens spore of ability; Suppress the germination of spore, stop in the germ invaded plants body, but very little to the mycelial lethal effect of cause of disease in the invaded plants body.
Mancozeb (mancozeb) molecular formula: C

4MnZn chemical name: the complex salt of two two thiocarbamoyl manganese of ethylene and zinc.
Mancozeb is the complex that maneb and zinc are formed, and belongs to the wider protective fungicide of fungicidal spectrum.It mainly is the oxidation that suppresses pyruvic acid in the thalline.Effective to multiple diseases such as the anthracnose on fruit tree, the vegetables, early blight, simultaneously its normal and systemic fungicide is mixed, and is used for the generation of delaying drug resistance.
No matter be pyraclostrobin, Propineb, zineb, mancozeb or other efficient germicides; Long-term use separately; Disease is developed immunity to drugs, cause the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, be unfavorable for environment sustainable development.And a kind ofly do not have the novel pesticide of cross resistance to prevent and treat pathogen if want newly developed, and then need screen 10,000～1.5 ten thousand compounds, expensive 1～1.5 hundred million dollar, the construction cycle is 6～10 years.And that the active ingredient of different effects mechanism is carried out is composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.
Pyraclostrobin is different with the mechanism of action of Propineb, zineb, mancozeb, and each other composite have good synergistic effect within the specific limits.And composite about pyraclostrobin and Propineb, zineb, mancozeb do not see relevant report at present at home and abroad as yet.

Embodiment
Below in conjunction with embodiment the present invention is further illustrated, but the present invention is not limited thereto.Percentage in following examples all is weight percentage.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Practice example one: pyraclostrobin and zineb (or mancozeb) are composite to the cucumber downy mildew Toxicity Determination
After the effective inhibition concentration scope of each medicament was confirmed in prerun, each medicament was established 5 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament cucumber downy mildew.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is following:
Wherein: a, b are respectively pyraclostrobin and Propineb, zineb or mancozeb shared ratio in combination
A is a pyraclostrobin
B is Propineb, zineb or mancozeb
