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 the agriculture chemicals fungicide field, be specifically related to contain the bactericidal composition of 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 active to the cucumber downy mildew inanimate object.
Powdery mildew of cucumber is one of Common Diseases in the cucumber cultivation.Because powdery mildew produces certain pesticide resistance in recent years, so that powdery mildew all can be fallen ill throughout the year.The general time underproduction is about 10%, but popular time underproduction 20%-40%.
Cucumber downy mildew seedling stage, strain phase all can be fallen ill the main harm blade.
Triazolone belongs to triazole bactericidal agent, and the common feature on the triazole bactericidal agent chemical constitution is to contain hydroxyl, substituted-phenyl and 1,2,4-triazole group compound on the main chain.This class medicament is except to the oomycetes non-activity in the Mastigomycotina, and the pathogen of Ascomycotina, Basidiomycotina and Deuteromycotina is all had activity, and its mechanism of action is damaged somatic cells film function for to affect the sterols biosynthesis.
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 such as downy mildew of garpe, potato late blight etc.Fluopicolide not only has unique mode of action, 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, developed the bactericidal composition of triazolone and fluopicolide, effectively remedy triadimefon fungicide this shortcoming to the oomycetes non-activity, enlarged 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 that contains triazolone and fluopicolide, has overcome triazolone after the two is composite to the shortcoming of downy mildew without bactericidal activity, has enlarged 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 that contains 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 preparation 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 mass percent (%): kaolin is supplied surplus
By proportioning triazolone and the former medicine of fluopicolide are carried out joining in the blender behind the air-flow crushing, in blender, add wetting agent, dispersant and carrier respectively by proportioning, stir and get final product.
Embodiment 2 preparations 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 is supplied surplus.
By proportioning triazolone and the former medicine of fluopicolide are carried out air-flow crushing, add various auxiliary agents and deionized water except thickener, put into together high-shear emulsion machine and mix, add thickener and further mix, grind through skin grinder, after the assay was approved and get final product.
In order to verify that the present invention to the powdery mildew of cucumber control efficiency, has carried out following experiment.
Single dose and composition are prepared into the acetone liquid storage that contains 1500mg/L active ingredient.According to the effective constituent determination requirement, the above-mentioned liquid storage of certain content is joined in the water that contains 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, cultivate at room temperature again, measure the percentage that leaf area infects, use the Abbot formula, these percentages are changed into render a service W.
W=（1-α/β）×100
α is for processing the fungal infection percentage of plant; β is the fungal infection percentage of plant of being untreated.Render a service as " 0 " and represent that the level that infects of processing plant is identical with the untreated level that infects; Render a service as " 100 " represent to process plant and do not infect.
The expection of composition is renderd a service and is used the Colby formula to determine, and compares with the effectiveness that records, and estimates the synergy of composition.
E=x+y-xy/100
X is the effectiveness of the compd A of working concentration when being a, represents with %; Y is the effectiveness of the compd B of working concentration when being b, represents with %; E be working concentration when being a and b compd A and the effectiveness 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 and render a service (%) | (%) renderd a service in expection | 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 |
According to table 1 as can be known, the composite rear control efficiency to powdery mildew of cucumber of triazolone and fluopicolide has synergistic effect, in addition, triazolone is active to the cucumber downy mildew inanimate object, after itself and fluopicolide is composite, enlarged the action spectrum of medicament, dispenser once can prevent and treat powdery mildew and downy mildew simultaneously.
