Description
Technical field
The invention belongs to disinfectant use in agriculture field, be specifically related to a kind of containing pyrrole metsulfovax bactericide and methoxy acrylic bactericide Fungicidal composition and application.
Background technology
New type bactericide pyrrole metsulfovax has efficiently, the bactericidal activity of wide spectrum, not only has excellent activity to rust, stalk break, also demonstrates good bactericidal activity to gray mold, powdery mildew and apple scab.Its structural formula is as follows:
This bactericide suitable for crop and fruit tree comprise apple, pears, peach, oranges and tangerines, tomato, cucumber, grape, wheat, paddy rice and lawn etc., are mainly used in preventing and treating stalk break, gray mold, scab, rust, powdery mildew, banded sclerotial blight and early blight etc.
Methoxy acrylic bactericide is the novel agricultural bactericide that another class after triazole bactericidal agent has the market vitality; there is protection, treat, root out, osmosis, can the fungal diseases such as most of oomycetes, sac fungi, basidiomycetes and Fungi Imperfecti be prevented and treated.In recent years, along with widely using of this series bactericidal agent, the control efficiency of methoxy acrylic bactericide to some diseases obviously declines.
Bactericide uses history to show, reuses same class medicament for a long time, very easily makes the part bacterial strain of disease develop immunity to drugs, and drug effect is obviously declined.By the antimicrobial combination with the different mechanism of action is used, sometimes can expand the fungicidal spectrum of medicament, delay the drug-fast generation of pathogen, play the synergistic effect of combination medicament, extend the service life of medicament.
Summary of the invention
The object of the present invention is to provide a kind of containing pyrrole metsulfovax bactericide and methoxy acrylic bactericide Fungicidal composition and application.
For achieving the above object, the present invention adopts technical scheme to be:
A kind of Fungicidal composition, containing A, B two kinds of active components, the weight ratio between component A and B component two component is 1:100
-100:1;

The synergistic function of the present composition to harmful fungoid is described further by the following example, but the present invention is only limitted to this absolutely not.Wherein said active component is bactericide pyrrole metsulfovax A in Fungicidal composition of the present invention and methoxy acrylic part bactericide B.
Method of testing and evaluation method as follows:
Active sample to be measured is respectively, pyrrole metsulfovax A, Enestroburin B1, alkene oxime amine B2, azoles amine bacterium ester B3, azoles bacterium ester B4, Fluoxastrobin B5, kresoxim-methyl B6, oxime bacterium ester B8, ZJ0712 B9, pyrrole metsulfovax A and Enestroburin B1, pyrrole metsulfovax A and alkene oxime amine B2, pyrrole metsulfovax A and azoles amine bacterium ester B3, pyrrole metsulfovax A and azoles bacterium ester B4, pyrrole metsulfovax A and Fluoxastrobin B5, pyrrole metsulfovax A and kresoxim-methyl B6, pyrrole metsulfovax A and oxime bacterium ester B8 and pyrrole metsulfovax A and ZJ0712 B9;
Concrete mode:
By active sample acetone solution (volume ratio of amounts of acetone and spouting liquid is equal to or less than 0.05), dilutes with the water containing 0.1% Tween 80, be mixed with desired concn liquid to be measured, the another liquid to be measured by setting proportions composition.On crops sprayer, liquid to be measured is sprayed on disease host plant, after 24 hours, carry out disease inoculation.According to disease feature, cultivate being placed in climatic chamber after the disease plant inoculating needing temperature control moisturizing to cultivate, after disease completes and infects, immigration hot-house culture.After contrasting fully morbidity, measure pathogen and infect Crop leaf area percentage, use Abbot formulae discovery, namely obtain observing effect (W):
W=（1-α/β）×100
In formula:
α: the fungal infection percentage of process crop;
β: the fungal infection percentage of untreated (blank) crop;
For " 0 ", effect represents that the level that infects of process crop is identical with the level that infects of untreated control crop; For " 100 ", effect represents that process crop is not infected.
The expection effect (calculating effect) of composition uses Colby formula (see R.S.Colby, weeds (Weeds), 1967,15,20-22) to determine, and compares with observation effect.
E=X+Y XY/100
In formula:
E: the expection effect (the calculating effect in following table) when working concentration is the composition of the active component A of a and b and B, represents with the % of untreated control;
X: the effect of active component A when working concentration is a, represents with the % of untreated control;
Y: the effect of active component B when working concentration is b, represents with the % of untreated control.
When observing effect value and being greater than calculating effect value, represent that composition has synergistic effect; When observing effect value and equaling to calculate effect value, expression composition is adduction; When observing effect value and being less than calculating effect value, expression composition is antagonism.
