Abstract
The invention discloses a sterilization composition. The sterilization composition is prepared from the effective ingredients of fenpyrazamine (A) and penthiopyrad or SYP-Z048 (B), and the mass ratio of A to B is 1:100 to 100:1. The composition is obvious in synergism, high in preventing effect, suitable for preventing and treating multiple diseases on melons, fruits and vegetables and especially suitable for preventing and treating gray mold.
Description
Technical field
The present invention relates to a kind of bactericidal composition, particularly relate to a kind of with the application of the amine benzene pyrrole bacterium ketone bactericidal composition that is main component and control corps diseases thereof, belong 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.

Embodiment
Being undertaken composite by the pesticide active ingredient of different types of structure, is a kind of effective means solving the problem such as cost and resistance in agricultural chemicals single dose application process at present.After the pesticide active ingredient mixing of different types of structure, usually show three kinds of type of action, i.e. 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 can improve actual control efficiency, and reduce the usage amount of agricultural chemicals, contributing to the generation of delaying drug resistance, is the important means of scientific prevention and cure damage by disease and insect.
The present composition has obvious synergistic function to Botrytis cinerea, and is not only the simple addition of two kinds of pharmacy effects, and this can be clear that from toxicity test experiment below and field control effectiveness test result very much.
Assays Example: composition is tested the Toxicity Determination of Botrytis cinerea
Subjects is Botrytis cinerea (Botrytiscinerea).
Test adopts mycelial growth rate method.Get experiment liquid that 5ml prepares to join the hot medium of 45ml (PDA medium is housed, 45-50 medicine) 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
Evaluation criterion: CTC≤80 are antagonism, 80 < CTC < 120 are summation action, and CTC >=120 are synergistic effect.
As can be seen from table 1,2, amine benzene pyrrole bacterium ketone and pyrrole metsulfovax or SYP-Z048 1 ︰ 100 ~ 100 ︰ 1 mixture in mass ratio, all have significant synergistic effect to Botrytis cinerea, when especially proportioning is between 1 ︰ 30 ~ 30 ︰ 1, synergy is more remarkable, and co-toxicity coefficient is all more than 170.
