Description
Technical field
The present invention relates to a kind of bactericidal composition, especially a kind of bactericidal composition containing fluorine azoles ring bacterium amine and its preventing and treating
The application of corps diseases, belongs to technical field of pesticide.
Background technology
Wheat and maize seed using loose smut of wheat and maize head smut as representative pass and soil-borne disease, sends out in recent years
Raw degree and area are brought significant damage to wheat and Maize Production, planted from efficient germicide in situation is risen year by year
Subprocessing is to control the effective way of these seed-borne diseases.
Fluorine azoles ring bacterium amine, english common name：Sedaxane, it is first just up to a kind of succinate dehydrogenase inhibitors of research and development
Series bactericidal agent, be mainly used as seed treatment, also can cauline leaf spraying, have special efficacy to seed-borne disease, the lasting period is up to 4 ~ 6 weeks.It is anti-
Controlling object includes miliary damping-off Pseudomonas, Puccinia, wheat class nuclear cavity Pseudomonas, Ustilago, Tilletia, Erysiphe, circle
Disease caused by nuclear cavity bacteria, Septoria, Ramularia etc..Fluorine azoles ring bacterium amine is in preventing and treating kind compared with other triazole bactericidal agents
Pass with the obvious advantage in disease.
But fluorine azoles ring bacterium amine is alone ineffective to rotten of the seedling stage as caused by lower fungus, and is unfavorable for the resistance to the action of a drug and controls
Reason.Preventing and treating spectrum can be expanded with other active ingredients compounding, moreover it is possible to delay resistance to the action of a drug occurrence and development to a certain degree.
The content of the invention
It is an object of the invention to：There is provided it is a kind of be adapted to agriculturally use, have remarkably to cereal crop seed-borne disease
Preventive effect, include the efficient bactericidal composite of fluorine azoles ring bacterium amine.
In order to solve the above technical problems, inventor has been surprisingly found that fluorine azoles by substantial amounts of indoor bioassay screening test
Ring bacterium amine is compounded with captan with certain proportion, and wheat and smut of maize bacterium are had significant synergies.
Captan, english common name：Captan, belong to the organic sulfurcontaining fungicide of conventional multi-bit point, using protective effect as
It is main, have certain therapeutic action concurrently.Captan wide sterilization spectrum, application mode is more various, is prevented and treated available for foliar spray a variety of
It is high and low to wait fungal disease, it can also be used to soil treatment (punching is applied, pouring root, mix soil and spread fertilizer over the fields) and a variety of works of seed treatment preventing and treating
Thing root disease.
Captan wide sterilization spectrum, but it is therapeutic inadequate, it is therapeutic insufficient captan can be made up with fluorine azoles ring bacterium amine compounding
Shortcoming.Captan is effective to root rot caused by lower fungus, and fluorine azoles ring bacterium amine can expand preventing and treating spectrum with captan compounding.
On the basis of above-mentioned discovery, by carrying out the quantitative analysis of synergy to composition, form the present invention's
Technical scheme, i.e., using fluorine azoles ring bacterium amine as a kind of active ingredient, using captan as another active ingredient, fluorine azoles ring bacterium amine and gram bacterium
Red mass ratio is 50:1~1:50, preferred mass ratio is 20:1~1:20, more preferably mass ratio is 10:1~1:10.
The present composition can be prepared into the formulation of suitable agricultural use with known method, active ingredient in preparation
Gross mass percentage composition is 5%-85%.
The adjuvant that uses includes dispersant, wetting agent, antifreezing agent, bleeding agent etc. and other had in the composition of the present invention
Beneficial to the active ingredient known substance that stable and drug effect plays in storage and use, commonly used or allow in pesticidal preparations
The various composition used, is not particularly limited, and specific composition and dosage are determined according to recipe requirements by simple experiment.
Product described in the invention can be provided in the form of finished product preparation, i.e., each material is blended in composition, combination
The composition of thing can also be provided with unit dose form, be used in mixed way according to needs.
The bactericidal composition of the present invention is mainly used in the preventing and treating of cereal crop kind biography and soil-borne disease, and especially wheat dissipates
Smut, the bunt of wheat, wheat base rot disease, maize head smut, Causal Organism of Maize Basal Stalk and bakanae disease of rice, are preferably used
In preventing and treating loose smut of wheat, the bunt of wheat, maize head smut, Causal Organism of Maize Basal Stalk and bakanae disease of rice.
Compared with prior art, had the beneficial effect that caused by the present invention：（1）Compared with single dose, the bactericidal composition is to disease
Evil has obvious synergistic effect, improves prevention effect；（2）Field dosage can be greatly decreased, effectively reduce environmental pollution
And residues of pesticides, and reduce production and use cost；（3）The mechanism of action of active ingredient is different in bactericidal composition,
The single selection pressure to pathogen is reduced, is advantageous to overcome and delays speed caused by pathogen resistance；（4）With single dose phase
Than preventing and treating spectrum can be expanded.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, present invention specific examples below
Illustrate, but the present invention is limited to absolutely not these examples.
The present composition using fluorine azoles ring bacterium amine and captan as active ingredient, between them combination have to disease obvious
Synergistic function, rather than just the simple addition of two kinds of pharmacy effects, specifically said with following biologicall test example
It is bright.
Biologicall test example 1：Fluorine azoles ring bacterium amine compounds with captan and the Toxicity Determination of Sporisorium reilianum is tried
Test.
Subjects：Sporisorium reilianum（Sporisoriumholci-sorghi）(pick up from outdoor through indoor separation training
Support）
Test method：Test reference《Farm-chemical indoor determination test rule NY/T 1156.17-2009 and NY/T 1156.6-
2006》, using turbidity-elisa plate method.Under aseptic technique, 75 μ L band bacteria culture fluids are drawn successively with liquid-transfering gun to distinguish
Add in each aperture of sterilized elisa plate.Then 75 μ L various concentrations are drawn successively from low concentration to high concentration with liquid-transfering gun
Decoction, make decoction with bacteria culture fluid mixed in equal amounts.And blank control is set, often handle 4 repetitions.
ELISA Plate is placed on shaking table, training 84h is shaken under the conditions of 28 DEG C, 150r/min.With ELIASA determine 650nm or
Absorbance under 655nm wavelength different disposals.
Record its data and carry out interpretation of result, carry out statistical analysis with DPS data processing softwares, calculate the EC of each medicament50,
Then co-toxicity coefficient is calculated by the abundant methods of Sun Yun（CTC）.Inhibiting rate calculation formula is as follows：
When CTC≤80, then composition shows as antagonism, and as 80 ＜ CTC ＜ 120, then composition shows as summation action, when
CTC >=120, then composition show as synergistic effect.
Survey toxicity index（ATI）=（Standard agent EC50/ reagent agent EC50）×100
Theoretical toxicity index（TTI）B in A percentage composition+B medicament toxicity index × mixture in=A medicament toxicity index × mixture
Percentage composition
Co-toxicity coefficient（CTC）=[mixture surveys toxicity index（ATI）/ mixture theoretical toxicity index（TTI）]×100
When CTC≤80, then composition shows as antagonism, and as 80 ＜ CTC ＜ 120, then composition shows as summation action, when
CTC >=120, then composition show as synergistic effect.
Toxicity Determination result of the test of the different disposal of table 1 to Sporisorium reilianum
Toxicity Determination result of the test shows that the proportioning of fluorine azoles ring bacterium amine and captan is 50:1-1:When between 50, to corn
Head smut bacterium has obvious synergistic effect, 20:1-1:When between 20, synergistic effect becomes apparent from, and co-toxicity coefficient is all 140
More than.
