Abstract
The invention relates to the field of pesticide bactericides, in particular to a bactericidal composition containing triazolone and dimethomorph. The bactericidal composition is characterized in that the mass ratio of triazolone to dimethomorph is (1:50)-(50:1). The bactericidal composition can be processed into such dosage forms as wettable powder or suspending agents. The bactericidal composition is used for preventing powdery mildew of potato and late blight of potato. After triazolone and dimethomorph are combined, the effect spectrum is expanded. The manpower, material resources and financial resources are saved when the bactericidal composition is applied.
Description
Technical field
The invention belongs to agriculture chemicals fungicide field, be specifically related to the bactericidal composition containing Triadimenol and dimethomorph.
Background technology
Along with the development of pesticide market, cost-effective product more and more welcomed by the people, triazolone is a kind of medicament of effectively preventing potato powdery mildew, but it is to potato late blight inactive.
Potato powdery mildew mainly causes harm blade, can infect petiole and stem stalk time serious.Blade is fallen ill, and is just filbert chlorisis fleck, expands variable color gradually and forms the large spot of dark brown.Scab two sides produces white powder to linen powder.
Potato late blight blade is caught an illness, the green and brown color spot point of the raw water soaking mode of present blade tip or leaf margin, tool light green color haloing around scab, and during high humidity, scab expands rapidly, in brown, and produces a circle white mould, and sporangiophore and sporangium.Serious blade of falling ill wither vertical, roll up, cause the black corruption of complete stool eventually.
Triazolone belongs to triazole bactericidal agent, and the common feature in triazole bactericidal agent chemical constitution is containing hydroxyl, substituted-phenyl and 1,2,4-triazole group compound on main chain.This kind of medicament, except to except oomycetes non-activity in Mastigomycotina, all has activity to the pathogen of Ascomycotina, Basidiomycotina and Deuteromycotina, and its mechanism of action, for affect sterols biosynthesis, makes somatic cells film function be damaged.
Dimethomorph single-mindedly kills Oomycete fungal bactericide, its action character is the formation destroying cell envelope, effect is had to each stage of oomycetes history of life, particularly responsive at the formation stages of sporangiophore and egg spore, under the concentration of polar region, (be less than 0.25 μ g/ml) be namely suppressed.
The present invention is directed to above problem, have developed the bactericidal composition of triazolone and dimethomorph, effectively compensate for triadimefon fungicide this shortcoming to oomycetes non-activity, expand the action spectrum of bactericidal composition, in use saved manpower, financial resources and material resources.
Summary of the invention
The present invention is the bactericidal composition containing triazolone and dimethomorph, overcomes triazolone to the shortcoming of late blight without bactericidal activity after the two is composite, expands the bactericidal action spectrum of preparation, can effectively prevent and treat potato powdery mildew and potato late blight.
The present invention is the bactericidal composition containing triazolone and dimethomorph, it is characterized in that: the mass percent of triazolone and dimethomorph is 1:50 ~ 50:1.
The formulation that described bactericidal composition can be processed into is wetting powder or suspending agent.
Described bactericidal composition is for preventing and treating potato powdery mildew and potato late blight.
Specific embodiment
Embodiment 1 prepares 45% triazolone dimethomorph wetting powder
Active ingredient mass percent (%): triazolone: fluopicolide salt is 15:30
Auxiliary agent mass percent (%): wetting agent: bay alcohol radical sodium sulphate 20.0; Dispersant: alkylsulfonate 20.0
Carrier quality percentage (%): kaolin supplies surplus
Join in blender after triazolone and the former medicine of dimethomorph being carried out air-flow crushing by proportioning, by proportioning respectively to adding wetting agent, dispersant and carrier in blender, stirring and get final product.
Embodiment 2 prepares 56% triazolone dimethomorph suspending agent
Active ingredient mass percent (%): triazolone: dimethomorph is 22:34
Auxiliary agent mass percent (%): wetting dispersing agent: sodium lignin sulfonate is 8.0; Thickener: xanthan gum is 2.0; Defoamer: organic silicone 2.0; Preservative: sodium citrate 0.5
Percentage of solvents (%): deionized water supplies surplus.
By proportioning, triazolone and the former medicine of dimethomorph are carried out air-flow crushing, add the various auxiliary agent except thickener and deionized water, put into high-shear emulsion machine together and mix, add thickener and mix further, through skin grinder grinding, after the assay was approved and get final product.
In order to verify that the present invention is to potato controlling powdery mildew effect, has carried out following experiment.
Single dose and composition are prepared into the acetone liquid storage containing 1500mg/L active ingredient.According to effective constituent determination requirement, the above-mentioned liquid storage of certain content is joined in the water containing 0.1% Tween-80, be mixed with the liquid 30mL of required animal.During mensuration, first liquid medicine jet is imposed on host plant, then inoculate pathogen, after 24h is cultivated in moisturizing, then cultivate at room temperature, measure the percentage that leaf area infects, use Abbot formula, these percentages are changed into effect W.
W=（1-α/β）×100
α is the fungal infection percentage of process plant; β is the fungal infection percentage of untreated plant.For " 0 ", effect represents that the level that infects of process plant is identical with the untreated level that infects; For " 100 ", effect represents that process plant is not infected.
The expection effect of composition uses Colby formula to determine, and compares with the effect recorded, and evaluates the synergy of composition.
E=x+y-xy/100
The effect of the compd A that x is working concentration when being a, represents with %; The effect of the compd B that y is working concentration when being b, represents with %; The compd A that E is working concentration when being a and b and the effect of B, represent with %.
Experimental result is as follows:
Table 1 contains the bactericidal composition of triazolone and dimethomorph to the control efficiency of powdery mildew of cucumber
| Title | Spraying medicine concentration (mg/L) | Measure effect (%) | Expection effect (%) | Synergy |
| Blank | - | (92.9 infect) | - | - |
| Triazolone | 1.0 | 69.9 | - | - |
| Dimethomorph | 2.0 | 45.6 | - | - |
| Triazolone: dimethomorph=1:2 | 1.0+2.0 | 85.3 | 83.6 | Synergistic effect |
Known according to table 1, triazolone and the composite rear control efficiency to potato powdery mildew of dimethomorph have synergistic effect, in addition, triazolone is to cucumber downy mildew inactive, after itself and dimethomorph is composite, expand the action spectrum of medicament, dispenser once can prevent and treat potato powdery mildew and late blight simultaneously.
