Abstract
The invention discloses a kind of bactericidal compositions of Fluxapyroxad-containsterilization, the bactericidal composition containing active components A Yu active constituent B, and active components A is selected from fluxapyroxad, and active constituent B is selected from any one following compound：Isoprothiolane, fenoxanil, probenazole, and active components A and the weight ratio of active constituent B are 1 ︰, 80~60 ︰ 1.The present composition has greater activity to the multiple diseases in various crop, and has apparent synergistic effect, expands fungicidal spectrum.And small, resistance of rainwater washing against, the obvious feature of synergy with dosage.
Description
The application is divisional application, and original application is that " one kind contains for the patent application of Shaanxi Welch Crop Protection Co., Ltd.
The bactericidal composition of fluxapyroxad ", the application Wei ︰ 2012101664956 of original application, original application date 2012.05.25.
Technical field
The invention belongs to technical field of pesticide, are related to a kind of bactericidal composition of Fluxapyroxad-containsterilization in crop disease
Using.
Technical background
Fluxapyroxad (fluxapyroxad) chemical name：3- (difluoro) -1- methyl-N- (3', 4', 5'- trifluoro [1,
1'- biphenyl] -2- base) -1-H- pyrazoles -4- amide, fluxapyroxad category pyrazol acid amide fungicide, succinate dehydrogenase inhibition
Agent.Superior lasting effect and lasting transmission characteristic are integrated in one.
Isoprothiolane (isoprothiolane) chemical name：Diisopropyl -1,3- dithiolane-a- phenyl malonic ester, point
Minor：C12H18O4S2, Isoprothiolane is systemic fungicide, has special efficacy to rice blast.Rice plant accumulates on leaf after absorbing medicament
Tissue, specifically focuses on cob and branch obstructs, so that germ be inhibited to invade, hinders germ lipid-metabolism, inhibits pathogen growth, play
Prevention and treatment.
Fenoxanil (fenoxanil) chemical name：N- (1- itrile group -1,2- dimethyl propyl) -2- (2,4 dichloro benzene oxygen
Base) propionamide, molecular formula：C15H18Cl2N2O2, fenoxanil is that a novel absorbability for preventing and treating rice blast is killed
Microbial inoculum has novel mechanism of action, belongs to melanin biosynthesis inhibitor (MBI), prevents and treats rice at blade face and underwater application
Seasonal febrile diseases excellent, and holding effect is significant.
Probenazole (probenazole) chemical name：3- allyloxy -1,2- benzisothiazole -1,1- titanium dioxide
Object, molecular formula：C10H9NO3S, probenazole can protect and eradicate extensively crop field effect, fruit tree, grassland, vegetables germ；In vitro
Slightly antimicrobial acivity in test；Rice is handled, promotes root system to absorb, cover crop is not by Pyricularia oryzae and the bacterial blight of rice
Bacterium is infected.
However, in the real process of agricultural production, the problem of pest control most easily produces is the production of pest resistance to insecticide
It is raw.Different cultivars ingredient is compounded, and is to prevent and treat the very common method of resistant insect.Heterogeneity is compounded, according to reality
Application effect, to judge that certain compounding is synergy, adduction or antagonism.In most cases, the compounding effect of pesticide
All be additive effect, really have the compounding of synergistic effect seldom, especially synergistic effect clearly, co-toxicity coefficient it is very high multiple
With just less.It is studied by inventor, after discovery compounds fluxapyroxad with Isoprothiolane, fenoxanil, probenazole
Good synergistic effect can be generated, and is compounded with Isoprothiolane, fenoxanil, probenazole about fluxapyroxad related
Report not yet discloses.
Summary of the invention
Fluxapyroxad and Isoprothiolane, fenoxanil, the long-time service of probenazole single dose may bring resistance generation, medicine
The problems such as effect decline, bactericidal composition proposed by the present invention contains active components A and active constituent B and suitable surface is living
Property agent and carrier.
A kind of bactericidal composition of Fluxapyroxad-containsterilization, containing active components A and active constituent B, active components A and activity
Ingredient B weight ratio is 1 ︰, 80~60 ︰ 1, and the active components A is selected from fluxapyroxad, and active constituent B is selected from Isoprothiolane, rice
One of pest amide, probenazole kind, active components A and active constituent B preferably weight ratio are 1 ︰, 60~40 ︰ 1；More preferably
Weight ratio for fluxapyroxad and Isoprothiolane is 1 ︰, 25~5 ︰ 1, the weight ratio of fluxapyroxad and fenoxanil be 1 ︰ 20~
The weight ratio of 10 ︰ 1, fluxapyroxad and probenazole is 1 ︰, 35~5 ︰ 1.
The bactericidal composition of the Fluxapyroxad-containsterilization is used to prevent and treat the disease of crops, and the crops include grain
It is food crop, legume crop, oil crops, fibre crops, sugar crop, melon crop, fruits crop, dry fruit crop, thermophilic
Good crop, root crop, flower crop, medicinal crop, crop, green manure pasture crop.
The disease include rice blast, leaf blight, bakanae disease, false smut, banded sclerotial blight, powdery mildew, rust, leaf spot,
Moire disease, net blotch, downy mildew, late blight, stripe disease.
The content of active constituent depends on amount of application when being used alone in the present composition, also depends on a kind of chemical combination
The mixed ratio and synergistic effect degree of object and another compound, at the same it is also related with target disease.In usual composition
The weight percentage of active constituent is the 1%~90% of total weight, preferably 5%~80%.According to different preparation classes
Type, active component content range are different.In general, liquid preparation contains by weight 1%~60% active material, preferably
Ground is 5%~50%；Solid pharmaceutical preparation contains by weight 5%~80% active material, preferably 10%~80%.

The embodiment of the present invention is the method combined using indoor toxicity test and field trial.First pass through indoor virulence survey
It is fixed, the synergy ratio (SR) after two kinds of medicaments compound by a certain percentage is defined, SR < 0.5 is antagonism, 0.5≤SR≤1.5
For summation action, SR > 1.5 is synergistic effect, on this basis, then carries out field trial.
Test method：After prerun determines the effective inhibition concentration range of each medicament, medicament sets 5 by active constituent content respectively
A dosage processing, if clear water compares.Reference《Farm-chemical indoor determination test rule fungicide》It carries out, speed is grown using mycelia
Rate method measures medicament to the virulence of crop germ.Colony diameter is measured with crossing method after 72h, calculates the net growth of each processing
Amount, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter -5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm (x), with minimum
Square law acquires virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.Simultaneously according to Wadley method
Two medicament different ratio synergy ratios (SR) are calculated, SR < 0.5 is antagonism, and 0.5≤SR≤1.5 are summation action,
SR > 1.5 is synergistic effect.Calculation formula is as follows：
Wherein：A, b is respectively active components A and active constituent B ratio shared in combination；
A is fluxapyroxad；
B is selected to one of Isoprothiolane, fenoxanil, probenazole and is planted.
