Description
Technical field
The invention belongs to biological bactericide fields, and in particular to be a kind of bactericidal composition containing benzo alkene fluorine bacterium azoles
And its application for preventing corps diseases.
Background technology
Powdery mildew is a kind of worldwide disease occurred extensively, and chemical pesticide control powdery mildew, mesh are mainly used in production
Before rely primarily on benzimidazole, triazole type, methoxy acrylic bactericide.However, killing for single kind is used for a long time
Microbial inoculum can make disease generate different degrees of resistance, and control effect reduces.
Benzo alkene fluorine bacterium azoles are a kind of pyrazole amide series bactericidal agents, by inhibiting on mitochondrial inner membrane in electron transport chain
Succinate dehydrogenase so that disease fungus can not generate energy via breathing, and then disintegrate the growth of germ, and the compound is independent
Higher operating costs and the generation for being easy hair resistance again, to reduce the service life of pesticide species.
Terpenol is the biological bactericide of biological pesticide company of Israel exploitation, currently, having 40.2% terpenol mother
Medicine and 9% terpenol missible oil success industrialization, for preventing the diseases such as powdery mildew of strawberry and early blight of tomato.
Rational pesticide activity component compounding is to solve the common measures such as pesticide residue, resistance development, some pesticides are lived
Property ingredient compounding after, also have the function of in a certain range expand fungicidal spectrum, improve control effect, synergy, therefore,
How a hot spot obtaining the agriculture chemical compounding with above-mentioned effect as research is screened.Present inventor is by a large amount of
It tests, on the basis of the field control effectiveness test of determination of activity combination indoors, screening obtains benzo alkene fluorine bacterium azoles and terpenol compounding
Apparent synergistic function is shown to the prevention of multiple kinds of crops disease afterwards, after further research, completes the present invention,
Currently, it is not yet found that the relevant report compounded about terpenol and benzo alkene fluorine bacterium azoles.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide, a kind of control effect is good, environment amenable association
Same Synergistic bactericidal composition.
It is described to kill another object of the present invention is to provide the application that the bactericidal composition is used to prevent corps diseases
Bacteria composition is particularly suitable for preventing a variety of oomycetes diseases, such as downy mildew, powdery mildew, phytophthora root rot etc., meanwhile, it is of the invention
The prevention spectrum of agricultural chemical compound conjugate also necessarily covers the prevention spectrum of single active constituent.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of bactericidal composition, which is characterized in that active constituent includes at least benzo alkene fluorine bacterium azoles and terpenol, wherein
Benzo alkene fluorine bacterium azoles and the weight ratio of terpenol are preferably 30:1-1:20, further, the weight ratio is preferably 10:1-1：
1。
Further, in the bactericidal composition composition shared by benzo alkene fluorine bacterium azoles and terpenol weight percentage
For 1-90%, preferably 20-50%, remaining is the conventional auxiliary element in Pesticide formulation.
Further, the bactericidal composition can be processed into agricultural by the customary preparation methods in Pesticide formulation
On allow the arbitrary dosage form used, including but not limited to wettable powder, water dispersible granules, aqueous emulsion, microemulsion, dispersible oil
Suspending agent.
Further, bactericidal composition of the invention can provide i.e. in composition each substance in the form of finished product preparation
Mixing, can also be provided with unit dose form, directly be mixed, be then diluted to required dense in proportion in bucket or tank using preceding
Degree.
Further, other agricultural active ingredients, such as fungicide, desinsection can also be added in bactericidal composition of the invention
The agricultural actives ingredient such as agent, herbicide, fertilizer.
Further, bactericidal composition of the invention can also occur just in application before disease generation in disease
Phase or disease occur the later stage and use, and also it can be made to use respectively in difference, and can be caused harm according to disease degree, prevention of dosage is made
The difference of object, application method, use environment etc. changes within the scope of wider.
Compared with prior art, bactericidal composition of the invention has the beneficial effect that:
1, in certain range after active constituent terpenol and benzo alkene fluorine bacterium azoles compound in bactericidal composition of the invention
It is interior to reach apparent synergistic function, it is possible to reduce pesticide activity component usage amount improves control effect；
2, the active constituent mechanism of action is different in bactericidal composition of the invention, and the two combined use can be reduced
And/or delay the generation of pathogen drug resistance；
3, bactericidal composition control effect of the invention is good, and dosage is low, is particularly suitable for prevention oomycetes diseases.
