Abstract
The invention relates to a pesticide composition containing pyraclostrobin and triazoles. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from pyraclostrobin; the active ingredient B is selected from one of tebuconazole, diniconazole, flutriafol, hexaconazole, cyproconazole, triadimenol and bitertanol; the weight ratio of the active ingredient A to the active ingredient B is (1%-60%): (1%-60%). The active ingredients are added with aids and excipients to be prepared into wettable powder, water dispersible granules, a suspension agent or a suspension emulsion. The composition is used for preventing and controlling powdery mildew, alternaria leaf spot, scab, leaf spot disease, anthracnose, rust disease, epidemic disease, banded sclerotial blight and rice blast of crops, is resistant to rainwash, and has a remarkable synergistic effect.
Description
The application is divisional application, and original application is the patent application " a kind of composition pesticide containing pyraclostrobin and triazole type " of Shanxi Thompson Biological Technology Co., Ltd., and the application number of original application is ︰ 201110066540.6, and original application day is 2011.03.19.
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of composition pesticide in crop pest containing pyraclostrobin and triazole type.
Technical background
Pyraclostrobin (pyraclostrobin), molecular formula: C

Pyraclostrobin is the bactericide of BASF AG's latest model methoxy acrylic.Sterling is that white is to the tasteless crystalline solid of oldlace.The mechanism of action is 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.There is very strong inhibitory action to the growth of spore germination and leaf intramatrical mycelium, there is 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 to user and environment all safety close friends, is classified as " Candidate Agents reducing risk " by U.S. EPA.In addition, pyraclostrobin can produce positive physiological regulatory action to crop, the generation of its energy ethene suppressing, and crop can be helped like this to have longer time deposit bio-energy to guarantee maturity; The activity of the restore nitrification enzyme of crop can be significantly improved, mean the use that can reduce Nitrogen In Soils fertilizer, thus reduce underground water mitigation further; When crop is subject to viral attack, it can accelerate the formation of resisting albumen--and identical with the synthesis of crop self salicylic acid synthetic to degeneration-resistant albumen.Pyraclostrobin is the efficient mitochondrial respiratory inhibitor after improving on kresoxim-methyl basis, is the o-methyl-phenyl-that substituted for N-rubigan pyrazolyl in kresoxim-methyl molecular structure, and the another methoxy acrylic wide-spectrum bactericide of exploitation.Its activity is higher, is at present with 3 times of series bactericidal agent.And kresoxim-methyl just has the report occurred about wheat powdery mildew resistance for 1 year afterwards in practical application, to 2000 resistant spores (2%-99%) in the north of Germany, the existing a large amount of report in the north and Britain of France.The current preventive effect to powdery mildew is existing at home declined.
No matter be pyraclostrobin, effective active composition B or other efficient germicides, be used alone for a long time, easily make disease develop immunity to drugs, cause the problems such as dosage increasing, preventive effect reduction, lasting period shortening, be unfavorable for environment sustainable development.The active ingredient of the different mechanism of action is carried out composite, is to delay disease to develop immunity to drugs conventional method, and according to the effect in production application, judge this composite be synergistic effect or antagonism.Complex role is significantly filled a prescription, and can significantly improve preventive effect, greatly reduces the dosage of agricultural chemicals, also can expand fungicidal spectrum, improves germicidal efficiency, alleviates pollution to environment.Pyraclostrobin is different from the effective active composition B mechanism of action, mutually composite have good synergistic effect within the specific limits, and about Tebuconazole, olefin conversion, Flutriafol, own azoles alcohol, cyproconazole, Triadimenol, bitertanol relevant composite, there is not yet relevant report at home and abroad at present.
Summary of the invention
The object of the invention is to propose a kind ofly have that synergistic effect, use cost are low, preventive effect is good containing pyraclostrobin and effective active composition B bactericidal composition.
The present invention is achieved through the following technical solutions:
