Description
Technical field
The present invention relates to a kind of bactericidal composition, the application of especially a kind of bactericidal composition containing pyrrole bacterium benzene prestige and control corps diseases thereof, belongs to technical field of pesticide.
Background technology
Grape grey mould, also known as Mild Powder, is one of Major Diseases of grape, and pathogen is the pathogen of Botrytis cinerea (Botrytiscinerea), belongs to Deuteromycotina Botrytis fungi.This pathogen main harm inflorescence, young fruit and will mellow fruit.Hypsography low-lying, young sprout excessive growth closing, ventilation and penetrating light is poor, extensive management, weedy, and fertilising is not enough, the vineyard that insect pest is serious, and grape grey mould occurs heavier.Occur because gray mold can spread harm, large area plant usually can be caused dead, and cause production declining, product qualitative change is bad, seriously constrains the development that grape is produced.Main use chemical agent is Sukeling, iprodione etc. at present.Drug-resistant mutation is easily there is because ash arrhizus bacteria has abnormal genetic variation potential, use such chemical bactericide that field pathogen can be made to develop immunity to drugs to these chemical agents in large quantities for a long time, the dosage of chemical bactericide is caused sharply to increase, environment is caused simultaneously and pollute significantly, too increase the drug cost of peasant.
Pyrrole bacterium benzene prestige, english common name: pyribencarb, the new type bactericide of Benzylcarbamate structure.By destroying the electron transport system of pathogen cell Mitochondria, hindering pathogen spore germination and after preventing spore-germination, infecting of host being played a role.The multiple diseases such as gray mold, stalk break of this bactericide to crops all has good effect.But the production that pyrrole bacterium benzene prestige is current and use cost all higher, and be used alone for a long time and also have very large resistance risk.
By the pesticide active ingredient Combination application of pyrrole bacterium benzene prestige and other structure type, there is the composition of synergistic effect can not only significantly improve actual preventive effect, reduce dosage and cost, also help avoid the generation of germ resistance and delay drug-fast generation speed, the problem such as resistance and cost in current agricultural chemicals single dose application process can be solved.
Summary of the invention
The object of the present invention is to provide that a kind of new resistance risk is little, cost is low, bactericidal composition that good drug efficacy, lasting period are long.
Inventor, by a large amount of indoor bioassay test and field control effectiveness test, surprisingly finds that any one in pyrrole bacterium benzene prestige and Fluoxastrobin, pyraclostrobin, oxime bacterium ester is with after certain proportion mixture, has significant synergistic effect to diseases such as gray molds.

The present composition possesses following advantage: one is that composition synergistic effect is obvious, and drug effect significantly improves; Two is that composition drug effect improves, and field rate declines, and reduces production and use cost, reduces residue of pesticide and environmental pollution; Three is that composition is made up of the active ingredient of different mechanism of action, and action site increases, and is conducive to overcoming and delay the drug-fast generation of germ.
Embodiment
After different pesticide active ingredient mixing, usually show three kinds of type of action: summation action, synergistic effect and antagonism.But be specially which kind of effect, unpredictable, only have and just can be known by lot of experiments.Compound synergic is well filled a prescription, and owing to significantly improving actual control efficiency, reduces the usage amount of agricultural chemicals, thus has delayed the drug-fast generation speed of germ widely, is the important means of scientific prevention and cure disease.
Inventors performed a large amount of indoor bioassay tests and field control effectiveness test, to find in pyrrole bacterium benzene prestige and Fluoxastrobin, pyraclostrobin, oxime bacterium ester that any one combines and has significant synergistic function to ash arrhizus bacteria etc., and be not only the simple addition (referring to Assays Example) of two kinds of medicaments.
Assays Example: pyrrole bacterium benzene prestige and Fluoxastrobin, pyraclostrobin, the composite Toxicity Determination to Botrytis cinerea (Botrytiscinerea) of oxime bacterium ester are tested
Test adopts mycelial growth rate method.Get experiment liquid that 5ml prepares to join the hot medium of 45ml (rye medium is housed, 45-50 DEG C) conical flask in, after shaking up, pour rapidly diameter 90mm glass culture dish into, band medicine medium 12ml poured into by each culture dish, each process 4 repetition, horizontal rest, cooling after flat board.Cut bacterium cake with diameter 5mm card punch from the examination bacterium edge that supplies cultivating 7d, the one side with mycelia received on the malicious medium of band with choosing pin, all operations all carries out sterile working at superclean bench.After process, flat board is placed in the constant temperature aseptic culture case of 25 DEG C and cultivates, after 7d, adopt right-angled intersection method to measure the colony diameter of each process respectively, calculate the mean value of each process colony diameter, the average net growth of colony diameter and mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate (%)=[(control group net growth-processed group net growth)/control group net growth] × 100
Mycelial growth inhibition rate is converted into probability value (y), and liquor strength (μ g/ml) converts logarithm value (x) to, calculates virulence equation and concentration EC in suppressing with method of least squares
50, 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 EC
50/ reagent agent EC
50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100.
CTC≤80 are antagonism, and 80 < CTC < 120 are summation action, and CTC >=120 are synergistic effect.
From table 1,2,3 results, in pyrrole bacterium benzene prestige and Fluoxastrobin, pyraclostrobin, oxime bacterium ester, any one is composite, when proportioning is between 100: 1 ~ 1: 100, co-toxicity coefficient is all more than 120, to Botrytis cinerea, there is synergistic effect, especially, time between 30: 1 ~ 1: 30, co-toxicity coefficient is all more than 170.
