The invention discloses a fungicidal composition. Effective ingredients of the fungicidal composition comprise benzovindiflupyr and pyrisoxazole, wherein the mass ratio of benzovindiflupyr to pyrisoxazole ranges from 50:1 to 1:50. The fungicidal composition has the obvious synergistic effect and can be applied to disease damage prevention and control of cereal crops, vegetables and fruits, especially prevention and control over rice blast, banded sclerotial blight, powdery mildew, gray mold and sclerotiniose.
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 anti-
Control the application of corps diseases, belong to technical field of pesticide.
Background technology
Succinate dehydrogenase inhibitors is the focus of current antibacterial research, and Ge great pesticide company has all put into number to it
Huge reasearch funds, occupy a tiny space on future market with it.Several succinate dehydrogenase inhibitors of listing at present
Because its mechanism of action is novel, excellent effect, liked by users.
Benzo alkene fluorine bacterium azoles, English name: benzovindiflupy, is the SDHI series bactericidal agent of Syngenta Co., Ltd's exploitation, right
Gray mold, wheat powdery mildew have specially good effect.But benzo alkene fluorine bacterium azoles is used alone relatively costly, and easily Induced resistance produces, from
And reduce 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, comprise
The efficient bactericidal composite of 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
Compound with certain proportion with chlorine nalidixic bacterium ester, powdery mildew of cucumber, graw mold of tomato, gray mold of cucumber are had significant potentiation and make
With.
Chlorine nalidixic bacterium ester, for the independently developed strobilurin fungicide of China, to rice blast, banded sclerotial blight,
False smut, powdery mildew, gray mold are effective.But it is higher that chlorine nalidixic bacterium ester is used alone resistance risk, develop compound synergic compositions
Delaying drug resistance can produce and reduce drug cost.
On the basis of above-mentioned discovery, through compositions is carried out symphyogenetic quantitative analysis, define the present invention's
Technical scheme, is i.e. a kind of effective ingredient with benzo alkene fluorine bacterium azoles, is another effective ingredient with chlorine nalidixic bacterium ester, benzo alkene fluorine bacterium azoles
Being 50:1 ~ 1:50 with the mass ratio of chlorine nalidixic bacterium ester, preferable ratio is 10:1 ~ 1:10.
The present composition can be prepared as being suitable for the dosage form of agricultural use, effective ingredient in preparation by known method
Gross mass percentage composition is 5%-90%.
The adjuvant used in the present composition includes dispersant, wetting agent, antifreezing agent, penetrating agent etc. and other is useful
In effective ingredient stable and known substance of drug effect performance in storage and use, it is all pesticidal preparations to be commonly used or allows to make
Various compositions, be not particularly limited, concrete composition and consumption are determined by simple experiment according to recipe requirements.
Bactericidal composition of the present invention can provide with finished product preparation form, and i.e. in compositions, each material is the most blended, compositions
Composition can also provide with unit dose form, according to need be used in mixed way.
Bactericidal composition of the present invention is mainly used in the disease of the crops such as Cereal, veterinary antibiotics, oil plant, especially Semen Tritici aestivi
Powdery mildew, powdery mildew of cucumber, graw mold of tomato, gray mold of cucumber, rice blast, rice sheath blight disease, wheat sharp eyespot anti-
Control.
Compared with prior art, the present invention produce have the beneficial effect that (1) compared with single dose, this bactericidal composition is to disease
Evil has obvious potentiation, improves prevention effect；(2) field dosage can be greatly decreased, effectively reduce environmental pollution and agriculture
Medicine remains, and reduces production and use cost；(3) compared with benzo alkene fluorine bacterium azoles single dose, bactericidal composition increases chlorine pyridine bacterium
Ester can be composed with expanding prevention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, present invention specific examples below
Illustrate, but the present invention is limited to absolutely not these examples.
The combination of active principles of different pesticide is compounded, is the various problems in pesticide single dose application process that solve at present
A kind of effectively and quick way.After the pestsides synthesis of different cultivars, typically exhibit three kinds of type of action: be i.e. added work
With, 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.Compounding
The good formula of potentiation, owing to significantly improving actual prevention effect, reduces the usage amount of pesticide, gives full play to each group of pesticide
The advantage divided, is the important means of integrated control.
The present composition, with benzo alkene fluorine bacterium azoles and chlorine nalidixic bacterium ester as effective ingredient, combines between them and has disease
Significantly synergistic function, and it is not only the simple addition of two kinds of pharmacy effects, specifically use following Assays Example
It is illustrated.
Assays Example: benzo alkene fluorine bacterium azoles toxicity test to cucumber powdery mildew's pathogen compounding with chlorine nalidixic bacterium ester is tested
Subjects: powdery mildew of cucumber pathogenic bacteria (Sphaerotheca fuliginea)
This test uses pot-culture method.Sowing sense powdery mildew of cucumber kind, takes the cucumber seedling growing to 2 leaf periods, often processes 5
Basin, numbers standby.On the basis of pilot study, according to agent activity, 5-7 series mass concentration is set.Medicinal liquid is uniform
Spray in blade face to whole moistenings, treat that medicinal liquid natural air drying is standby.And set containing only solvent and surfactant without effectively becoming
Blank is made in the process divided.24h after medicine, inoculates powdery mildew spore suspension.The compound method of spore suspension is as follows: take length
Full Powdery Mildew cucumber leaves, with the pure water added with a small amount of surfactant, washes lower Fresh spores, and making concentration is
1x105The spore suspension of individual/mL.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 (g/ml) is converted into logarithm value (x), calculates with method of least square
Concentration EC in virulence equation and suppression50, toxicity index and the co-toxicity coefficient (CTC) of medicament is calculated according to the abundant method of Sun Yun.
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100
B in the percentage composition+B medicament toxicity index × mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture
Percentage composition
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 as summation action；
CTC >=120, compositions shows as potentiation.
