Abstract
The invention discloses a kind of bactericidal composition, its effective ingredient is benzo alkene fluorine bacterium azoles and ZJ0712, and both mass ratioes are 50:1-1:50.The present composition has obvious potentiation, can be used for the preventing and treating of the disease control of veterinary antibiotics, cereal crop, especially gray mold and powdery mildew.
Description
Technical field
The present invention relates to a kind of bactericidal composition, a kind of bactericidal composition containing benzo alkene fluorine bacterium azoles
And the application of preventing and treating corps diseases, belong to technical field of pesticide.
Background technology
Succinate dehydrogenase inhibitors is the focus of current antibacterial research, and it is all put into by Ge great pesticide company
Large amounts of reasearch funds, occupy a tiny space on future market with it.Several ambers of listing at present
Amber dehydrogenase inhibitor is novel because of its mechanism of action, and excellent effect is liked by users.
Benzo alkene fluorine bacterium azoles, English name: benzovindiflupy, is that the SDHI class of Syngenta Co., Ltd's exploitation is killed
Microbial inoculum, has specially good effect to gray mold, wheat powdery mildew.But benzo alkene fluorine bacterium azoles is used alone relatively costly, and
Easily Induced resistance produces, thus reduces service life.
Summary of the invention
It is an object of the invention to: provide a kind of be suitable for agriculturally use, disease is had outstanding prevention effect
, the efficient bactericidal composite comprising benzo alkene fluorine bacterium azoles.
For solving above-mentioned technical problem, inventor is screened by substantial amounts of bioassay, has been surprisingly found that benzo alkene
Fluorine bacterium azoles compounds with certain proportion with ZJ0712, to powdery mildew of cucumber, graw mold of tomato, gray mold of cucumber
Have significant synergies.
ZJ0712, for the independently developed strobilurin fungicide of China, to powdery mildew,
Downy mildew is effective, the most effective to gray mold.But it is higher that ZJ0712 is used alone resistance risk, exploitation is multiple
Join synergistic composition and can reduce drug cost.
On the basis of above-mentioned discovery, through compositions is carried out symphyogenetic quantitative analysis, define this
The technical scheme of invention, is i.e. a kind of effective ingredient with benzo alkene fluorine bacterium azoles, is that another is effective with ZJ0712
Composition, benzo alkene fluorine bacterium azoles is 50:1～1:50 with the mass ratio of ZJ0712, and preferable ratio is
10:1～1:10.
The present composition can be prepared as being suitable for the dosage form of agricultural use by known method, in preparation effectively
The gross mass percentage composition of composition is 5%-90%.
In the present composition use adjuvant include dispersant, wetting agent, antifreezing agent, penetrating agent etc. and
Other is of value to effective ingredient stable and known substance of drug effect performance in storage and use, is all pesticide
In preparation, the conventional or various compositions of permission use, are not particularly limited, and concrete composition and consumption are according to formula
Require to be determined by simple experiment.
Bactericidal composition of the present invention can provide with finished product preparation form, and i.e. in compositions, each material is the most blended,
The composition of compositions can also provide with unit dose form, is used in mixed way according to needs.
Bactericidal composition of the present invention is mainly used in the disease of the crops such as Cereal, veterinary antibiotics, oil plant, especially
It is wheat powdery mildew, powdery mildew of cucumber, Fructus Benincasae chiehquae powdery mildew, graw mold of tomato, gray mold of cucumber, Fructus Solani melongenae
Gray mold, grey mould fruit rot of strawberry, the preventing and treating of grape grey mould.
Compared with prior art, the present invention produce have the beneficial effect that (1) compared with single dose, this sterilization group
Compound has obvious potentiation to disease, improves prevention effect；(2) field dosage can be greatly decreased,
Effectively reduce environmental pollution and pesticide residues, and reduce production and use cost；(3) with benzo alkene fluorine bacterium
Azoles single dose is compared, and bactericidal composition increases ZJ0712 and can compose with expanding prevention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, the present invention is with in detail below
Embodiment illustrates, but the present invention is limited to absolutely not these examples.
The combination of active principles of different pesticide is compounded, be solve at present in pesticide single dose application process each
A kind of effective and quick way of the problem of kind.After the pestsides synthesis of different cultivars, typically exhibit three kinds of works
By type: i.e. summation action, potentiation and antagonism.But it is specially which kind of effect, it is impossible to prediction,
Only just be can know that by lot of experiments.The good formula of compound synergic, owing to significantly improving actual preventing and treating
Effect, reduces the usage amount of pesticide, gives full play to the advantage of each component of pesticide, is the important of integrated control
Means.
The present composition, with benzo alkene fluorine bacterium azoles and ZJ0712 as effective ingredient, combines disease between them
Evil has an obvious synergistic function, and is not only the simple addition of two kinds of pharmacy effects, specifically in order to
Lower Assays Example is illustrated.
Assays Example: benzo alkene fluorine bacterium azoles virulence to cucumber powdery mildew's pathogen compounding with ZJ0712 is surveyed
Fixed test
Subjects: powdery mildew of cucumber pathogenic bacteria (Sphaerotheca fuliginea)
This test uses pot-culture method.Sowing sense powdery mildew of cucumber kind, takes the Fructus Cucumidis sativi growing to 2 leaf periods
Seedling, often processes 5 basins, numbers standby.On the basis of pilot study, according to agent activity, 5-7 is set
Individual series mass concentration.Medicinal liquid is uniformly sprayed in blade face to whole moistenings, treat that medicinal liquid natural air drying is standby.
And set and make blank containing only solvent and surfactant without the process of effective ingredient.24h after medicine, inoculation
Powdery mildew spore suspension.The compound method of spore suspension is as follows: takes and covers with Powdery Mildew cucumber leaves,
With the pure water added with a small amount of surfactant, washing lower Fresh spores, making concentration is 1x105Individual/mL's
Spore suspension.After cultivating 7d in greenhouse, record the lesion area on every strain cucumber seedling blade and add up,
Calculate disease index and prevention effect.
Powdery mildew of cucumber grade scale
0 grade: anosis；
1 grade: sorus area accounts for less than the 5% of one-piece blade area；
3 grades: sorus area accounts for the 6%-10% of one-piece blade area；
5 grades: sorus area accounts for the 11%-20% of one-piece blade area；
7 grades: sorus area accounts for the 21%-50% of one-piece blade area；
9 grades: sorus area accounts for more than the 50% of one-piece blade area.
Drug effect computational methods:
Prevention effect is converted into probability value (y), and liquor strength (μ g/ml) is converted into logarithm value (x), with
Method of least square calculates concentration EC in virulence equation and suppression50, according to the abundant method of Sun Yun calculate medicament toxicity index and
Co-toxicity coefficient (CTC).
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100
Percentage composition+B medicament the virulence of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture
The percentage composition of B in index × mixture
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)]
×100
Evaluation criterion: CTC≤80, compositions shows as antagonism；80 ＜ CTC ＜ 120, compositions shows
For summation action；CTC >=120, compositions shows as potentiation.
