Abstract
The invention relates to the field of pesticide bactericides, in particular to a bactericidal composition containing triazolone and fluopicolide. The bactericidal composition is characterized in that the mass ratio of triazolone to fluopicolide 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 cucumber and downy mildew of cucumber. After triazolone and fluopicolide 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 fluopicolide.
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 powdery mildew of cucumber, but it is to cucumber downy mildew inactive.
Powdery mildew of cucumber is one of Common Diseases in cucumber cultivation.Because powdery mildew produces certain pesticide resistance in recent years, powdery mildew all can be fallen ill throughout the year.The general time underproduction is about 10%, and the popular time can underproduction 20%-40%.
Cucumber downy mildew seedling stage, Adult plant all can be fallen ill, main harm blade.
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.
Fluopicolide is a kind of amide-type systemic fungicide of Beyer Co., Ltd's exploitation, is mainly used in preventing and treating the microbial disease of Oomycete cause of disease as downy mildew of garpe, potato late blight etc.Fluopicolide not only has unique mode of action, and with other series bactericidal agent without cross resistance, and it is active to have good holding effect.
The present invention is directed to above problem, have developed the bactericidal composition of triazolone and fluopicolide, 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 fluopicolide, overcomes triazolone to the shortcoming of downy mildew without bactericidal activity after the two is composite, expands the bactericidal action spectrum of preparation, can effectively prevent and treat powdery mildew of cucumber and cucumber downy mildew.
The present invention is the bactericidal composition containing triazolone and fluopicolide, it is characterized in that: the mass percent of triazolone and fluopicolide 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 used for preventing and treating powdery mildew of cucumber and cucumber downy mildew.
Specific embodiment
Embodiment 1 prepares 30% triazolone fluopicolide wetting powder
Active ingredient mass percent (%): triazolone: fluopicolide salt is 20:10
Auxiliary agent mass percent (%): wetting agent: bay alcohol radical sodium sulphate 25.0; Dispersant: alkylsulfonate 20.0
Carrier quality percentage (%): kaolin supplies surplus
Join in blender after triazolone and the former medicine of fluopicolide 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 35% triazolone fluopicolide suspending agent
Active ingredient mass percent (%): triazolone: fluopicolide salt is 20:15
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 fluopicolide 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 powdery mildew of cucumber control efficiency, carry 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 fluopicolide 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 | 2.0 | 72.4 | - | - |
| Fluopicolide | 1.0 | 56.0 | - | - |
| Triazolone: fluopicolide=2:1 | 2.0+1.0 | 88.4 | 87.9 | Synergistic effect |
Known according to table 1, triazolone and the composite rear control efficiency to powdery mildew of cucumber of fluopicolide have synergistic effect, in addition, triazolone is to cucumber downy mildew inactive, after itself and fluopicolide is composite, expand the action spectrum of medicament, dispenser once can prevent and treat powdery mildew and downy mildew simultaneously.
