Description
Technical field
The present invention relates to technical field of pesticide, more particularly to a kind of sterilization group containing probenazole and waxy Bacillus
Compound.
Background technology
Probenazole, English name：Probenazole, it is one kind of Japanese Meiji Seika Kaisha, Ltd.'s exploitation
Inducing immunity bactericide, by exciting plant in itself to react immune (resistance) of disease to realize protection effect, pass through plant
Thing root absorption, and relatively rapidly infiltration is conducted to plant each several part.
Waxy Bacillus, English name：Bacillus cereus, it is a kind of microbial pesticide, by colonizing, shifting
And antagonism, in plant surface amount reproduction, turn into the contenders of plant site and space microenvironment, so directly hinder
Scratch and disturb colonizing and growing for external harmful pathogen.Due to reduce quantity that harmful pathogen colonizes on plant or
Capture and infected site, reduced infecting for harmful pathogen, so that infringement of the crop from other harmful pathogens.
In agricultural production, controlling disease is easiest to generate the problem that the drug-fast generation of germ.And by it is different into
The mixed pesticide divided, it is to prevent and treat the very common method of resistance disease.Screened by formulation of pesticide, synergy is significantly formulated, and can be had
Effect improves actual prevention effect, reduces dosage, delays Disease Resistance to develop, be the important means of the disease comprehensive regulation.
Study, found probenazole and waxy Bacillus with certain weight than mixture, application by inventor
There is good synergistic effect in the preventing and treating of rice blast.
At present, the research for probenazole being applied to rice blast to waxy Bacillus mixture there are no related report
Road.
The content of the invention
It is an object of the present invention to provide a kind of bactericidal composition containing probenazole and waxy Bacillus, it is used for
Rice blast is prevented and treated, its Synergistic is notable, can greatly improve drug effect, reduces pesticide cost, is advantageous to delay Disease Resistance
Development.
The present invention adopts the technical scheme that：A kind of bactericidal composition containing probenazole and waxy Bacillus, has
Effect composition be made up of probenazole and waxy Bacillus, set content as 9,000,000,000 living spores/gram waxy Bacillus
Female medicine is 90% active compound, and the weight ratio of probenazole and waxy Bacillus is 8：1~1：8, it is preferred that probenazole and
The weight ratio of waxy Bacillus is 4:1.
Described bactericidal composition, the percentage by weight of probenazole are 2.5-20.0%, the weight of waxy Bacillus
Amount percentage is 2.5-20%, i.e., the content of waxy Bacillus be 2.5 hundred million spores/gram~2,000,000,000 spores/gram.
Described bactericidal composition can add corresponding auxiliary element, make according to well known to a person skilled in the art method
It is standby into agriculturally acceptable any formulation, it is relatively good for suspending agent, wettable powder etc..
The auxiliary element that described bactericidal composition is prepared into pesticidal preparations addition includes filler, solvent, dispersant, wetting
Agent, emulsifying agent, antifreeze, defoamer, thickener, stabilizer or it is other be beneficial to active ingredient in the formulation stablize and drug effect hair
The material waved.
The present invention has advantages below and significant technique effect:(1) two active ingredient mechanisms of action of the invention are not
Together, the two mutual mixture germ is not likely to produce resistance.(2) indoor biometricses result shows, probenazole and waxy Bacillus
Mixture has notable synergistic effect to rice blast according to a certain percentage, can greatly improve drug effect, advantageously reduces each single dose
Amount of application, pesticide cost is reduced, be advantageous to extend the life cycle of each single dose.
Embodiment
Technical scheme and technique effect are described further below by way of specific embodiment, institute of the present invention
The percentage stated is weight percentage.
First, indoor biometricses are tested
Embodiment 1:The Toxicity Determination of probenazole, waxy Bacillus and mixture to rice blast
After prerun determines the effective inhibition concentration scope of each medicament, by active constituent content, gradient sets 5 to each medicament respectively
Individual dosage processing, if clear water compares.Reference《Farm-chemical indoor determination test rule bactericide》Carry out, using mycelial growth speed
Rate method determines virulence of the medicament to rice blast.Colony diameter is measured with crossing method after 72h, calculates the net growth of each processing
Amount, mycelial growth inhibition rate.
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm value (x), with minimum
Square law tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value, medicine is calculated according to the abundant methods of Sun Yun
The toxicity index and co-toxicity coefficient (CTC) of agent.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent
Co-toxicity coefficient (CTC)=[mixture actual measurement 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 being added and made
With when CTC >=120, then composition shows as synergistic effect.
Statistical result is shown in Table 1.
