Abstract
The invention discloses a kind of efficient bactericidal composite, bactericidal composition containing active components A Yu active component B, active components A is selected from fluopyram, active component B is selected from any one compound following: dithianon, cyprodinil, captan, phosethyl-Al, Bravo, bromothalonil, and the weight ratio of active components A and active component B is 1 80～60 1.The present composition has greater activity to the multiple diseases in various crop, and has obvious synergistic effect, expands fungicidal spectrum.And have that dosage is little, resistance of rainwater washing against, the obvious feature of synergy.
Description
The application is divisional application, and original application is the patent application of Shaanxi Meibang Pesticide Co., Ltd.
" a kind of bactericidal composition ", Application No. 201210243178.X of original application, original application
Day is 2012-7-13.
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition in crop pest
Application.
Technical background
Fluopyram (Fluopyram) chemical name: N-{2-[3-chloro-5-(trifluoromethyl)-2-
Pyridine radicals) ethyl]-α, α, α-three fluoro-0-toluamide, molecular formula: C16H11ClF6N2O, it is
Mitochondrial respiratory is suppressed by hindering the electro transfer of succinate dehydrogenase in respiratory chain.Pass through
Suppress the several stages in the growth of pathogenic bacteria cycle to reach to control the purpose of pathogenic bacteria, mainly use
The microbial disease of ascus is prevented and treated on broad leaf crop.
But, in the real process of agricultural production, the problem that controlling disease is easiest to produce
It it is drug-fast generation.Different cultivars composition compounds, and is to prevent and treat the side that resistance is the most common
Method.Heterogeneity compounds, and according to practical application effect, judging that certain compounds is to increase
Imitate, add and or antagonism.In most cases, the compounding effect of agricultural chemicals all adds
And effect, really have synergistic effect compounding seldom, especially synergistic effect clearly,
Compounding that co-toxicity coefficient is the highest is the most less.Study through inventor, find fluorine pyrrole bacterium acyl
Amine and dithianon, cyprodinil, captan, phosethyl-Al, Bravo, bromothalonil are multiple
Good synergistic effect can be produced after joining, and about fluopyram and dithianon, phonetic bacterium
Cyclammonium, captan, phosethyl-Al, Bravo, bromothalonil compounded relevant report the most public
Open.
Summary of the invention
The purpose of the present invention is to propose to one and have that synergistic function, use cost be low, preventive effect
Good bactericidal composition.
The bactericidal composition that the present invention proposes contains active components A and active component B, and activity becomes
Dividing A and active component B weight ratio is 1 80～60 1, and described active components A is selected from
Fluopyram, active component B is selected from dithianon, cyprodinil, captan, three second
One of phosphonic acids aluminium, Bravo, bromothalonil are planted.Active components A is more excellent with active component B
Weight ratio be 1 60～40 1；More preferably fluopyram and the weight ratio of dithianon
Being 1 25～15 1, fluopyram is 1 30～10 1 with the weight ratio of cyprodinil,
Fluopyram is 1 30～5 1 with the weight ratio of captan, fluopyram and triethylphosphine
The weight ratio of acid aluminium is 1 40～1 1, and fluopyram is 1 with the weight ratio of Bravo
30～5 1, fluopyram is 1 30～15 1 with the weight ratio of bromothalonil；Most preferably
Fluopyram is 1 15～5 1 with the weight ratio of dithianon, fluopyram and phonetic bacterium
The weight ratio of cyclammonium is 1 20～1 1, and fluopyram is 1 with the weight ratio of captan
20～1 5, fluopyram is 1 30～1 10 with the weight ratio of phosethyl-Al, fluorine pyrrole
Bacterium acid amides is 1 20～1 5 with the weight ratio of Bravo, fluopyram and the weight of bromothalonil
Amount ratio is 1 10～5 1；
The bactericidal composition that the present invention proposes is for preventing and treating the purposes of disease on crops, described
Crops include cereal crops, legume crop, fibre crops, sugar crop, melon crop,
Fruits crop, dry fruit crop, hobby crop, root crop, oil crops, flowers
Crop, medicinal crop, crop, green manure pasture crop；Described disease include powdery mildew,
Downy mildew, epidemic disease, rust, anthracnose, gray mold, scab, net blotch, glume blight,
Leaf mold, ring spot, rice blast, banded sclerotial blight, shot hole, leaf spot, spot defoliation,
Anthrachose of grape.
In the present composition, the content of active component depends on amount of application when being used alone, also
Depend on the mixed ratio of a kind of compound and another kind of compound with or its synergistic effect degree,
Also the most relevant with target disease.Generally in composition, the weight percentage of active component is total
The 1%～90% of weight, is preferably 5%～80%.According to different preparation types, activity
Component content scope is different.Generally, liquid preparation contains by weight 1%～60%
Active material, preferably 5%～50%；Solid pharmaceutical preparation contains by weight 5%～80%
Active material, preferably 10%～80%.
The bactericidal composition of the present invention at least contains a kind of surfactant, when being beneficial to use
Active component dispersion in water.Surface-active contents is the 2%～30% of total formulation weight amount,
Surplus is solid or liquid diluent.
Surfactant selected by the bactericidal composition of the present invention is those skilled in the art institutes
Known: one or more in dispersant, wetting agent, thickener or defoamer can be selected from.
According to different dosage form, preparation can also contain stabilizer known in those skilled in the art, resist
Freeze agent etc..
The bactericidal composition of the present invention through dilution or directly can be used before use by user.
Its preparation can be prepared by processing method known in those skilled in the art, will active component with

The embodiment of the present invention is the method using Toxicity Determination and field test to combine.First
Synergy ratio by Toxicity Determination, after clear and definite two kinds of medicaments are compounding by a certain percentage
(SR), SR ＜ 0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, SR ＞ 1.5
For synergistic effect, on this basis, then carry out field test.
Test method: after prerun determines each medicament effective inhibition concentration scope, medicament is by effectively
Component content sets 5 dosage respectively and processes, if clear water comparison.With reference to " agricultural chemicals indoor biological is surveyed
Determine test rule bactericide " carry out, use mycelial growth rate method to measure medicament to crop germ
Virulence.After 72h with right-angled intersection method measure colony diameter, calculate each process net growth,
Mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) is changed
Become logarithm value (x), try to achieve virulence regression equation (y=a+bx) with least square method, and thus
Calculate the EC of every kind of medicament50Value.Calculate two medicament different ratio according to Wadley method simultaneously
Synergy ratio (SR), SR ＜ 0.5 is antagonism, and 0.5≤SR≤1.5 are made for being added
With, SR ＞ 1.5 is synergistic effect.Computing formula is as follows:
