The effective active ingredient of the bactericide composition comprises one of pyraclostrobin (A) and isoprothiolane or iprobenfos (B), and the weight ratio of A to B is (20-1): (1-80), the effective active ingredient is added with auxiliaries and an excipient to be prepared into water dispersible granules, a suspending agent and the like and is mainly used for preventing and controlling rice blast, banded sclerotial blight, bakanae disease and the like.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains pyraclostrobin and Isoprothiolane or IBP.
Technical background
Pyraclostrobin (pyraclostrobin), molecular formula: C
20H
23N
3O
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.
Isoprothiolane (isoprothiolane) molecular formula: C
12H
18O
4S
2, chemical name: diisopropyl-1,3-dithiolane-a-phenyl malonic ester.
Isoprothiolane is a systemic fungicide, and rice blast is had special efficacy.Rice plant accumulates on leaf texture after absorbing medicament, concentrates on cob and branch stalk especially, invades thereby suppress germ, hinders the germ lipid-metabolism, suppresses the germ growth, plays prevention and treatment.
IBP (iprobenfos), molecular formula are C
13H
21O
3PS, chemical name: O, O-diisopropyl-S-benzyl thiolophosphate.
IBP is different third kitazine, belongs to organophosphorus fungicide.Main interference cell membrane permeability stops some lipophilic chitin precursor through cytoplasma membrane, and chitinous biosynthesis block is hindered, and cell wall can not be grown, and suppresses the normal development of thalline.
No matter be pyraclostrobin, Isoprothiolane (IBP) or other efficient germicides, long-term use separately makes disease develop immunity to drugs easily, causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is 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 Isoprothiolane (IBP) mechanism of action, and each other composite have good synergistic effect within the specific limits.And composite about pyraclostrobin and Isoprothiolane (IBP) do not see relevant report at present at home and abroad as yet.

Embodiment
Below in conjunction with embodiment the present invention is further explained, 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 Isoprothiolane (or IBP) are composite to the rice blast 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 rice blast.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 Isoprothiolane (or IBP) shared ratio in combination
A is a pyraclostrobin
B is Isoprothiolane (or IBP)
Result of the test is as shown in the table:
