Description
Technical field
The invention belongs to technical field of pesticide, relate to the composite application of bactericide on wheat and the common disease of paddy rice of a kind of 2-cyano-3-amino-3-phenylancryic acetate-containing and own azoles alcohol.
Technical background
2-cyano-3-amino-3-phenylancryic acetate was synthesized by China Jiangsu Prov. Inst. of Agricultural Chemicals in 1998, belonged to 2-cyanoacrylate bactericide, obtained the interim registration card of Ministry of Agriculture's Pesticidal products in 2007, and preparation belongs to little malicious pesticide species.Former medicine outward appearance is the white solid powder.Chemical name: 2-cyanic acid-3-aminoacrylic acid ethyl ester.Structural formula is:
2-cyano-3-amino-3-phenylancryic acetate is effective to the disease that the reaping hook mushroom causes, has protective effect and therapeutic action.Be absorbed through root, upwards transporting property arranged on blade, towards the blade bottom and interlobate transporting property relatively poor.The result shows through field control effectiveness test, and 2-cyano-3-amino-3-phenylancryic acetate 25% suspending agent has the better prevention effect to wheat scab.
Own azoles alcohol is the triazole bactericidal agent of new generation by Syngenta Co.,Ltd's exploitation, is one of safest bactericide in the present triazole type.Outward appearance is the ecru loose powder, 110～112 ℃ of fusing points, and chemical name: (RS)-2-(2,4 dichloro benzene base)-1-(1H-1,2,4-triazol-1-yl)-oneself-2-alcohol, structural formula is:
Own azoles alcohol is to stay pure demethylation inhibitor, has the efficient sterilizing effect, and the disease that fungi especially Basidiomycota and Ascomycota are caused has the protection and the therapeutic action of broad spectrum activity.Can be used for paddy rice, fruit tree, peanut and other crops, can prevent and treat banded sclerotial blight, powdery mildew, black viral disease, leaf spot.
Long-term practical application shows; Own azoles alcohol is desirable to preventive effects such as multiple diseases such as alternaria leaf spot of apple, rice sheath blight disease, wheat sharp eyespots, but use cost is higher separately, is unfavorable for that large tracts of land promotes the use of; And along with the increase of usage amount, tangible pesticide resistance has appearred in some local diseases; 2-cyano-3-amino-3-phenylancryic acetate has good preventive and therapeutic effect to wheat diseases especially head blight, and long-term the use is prone to develop immunity to drugs.
The field is given birth to survey and is shown, there is synergistic effect preferably the composite back of 2-cyano-3-amino-3-phenylancryic acetate and own azoles alcohol to the disease on wheat and the paddy rice, and has delayed the generation of disease drug resistance.Do not see the relevant report of the composite product of relevant 2-cyano-3-amino-3-phenylancryic acetate and own azoles alcohol up to now as yet.
Summary of the invention

We have carried out mutual composite synergy research with compositions such as 2-cyano-3-amino-3-phenylancryic acetate and own azoles alcohol, and research is the method that adopts indoor bioassay and field trial to combine.Through indoor bioassay, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage on this basis, is carrying out field trial earlier.Draw final conclusion after data are analyzed.
Practice example one: 2-cyano-3-amino-3-phenylancryic acetate and own azoles alcohol are mixed and supply the reagent agent to be provided by Shaanxi Pucheng County Meibang Pesticide Co., Ltd. to the rice sheath blight disease Toxicity Determination.
Supply the examination bacterial classification: rice sheath blight disease, adopt back by Hanzhong City Yang County, Shaanxi Province, separate activation through the laboratory, through subsequent use after twice switching.
Each active constituent content of test medicine is designed 5 concentration of treatment respectively, be treated to contrast, the inhibitory action of rice sheath blight disease germ is carried out indoor measurement with blank.The mycelial growth rate method is adopted in test, earlier each proportioning is become the series concentration gradient.Will the rice sheath blight disease germ after secondary separation is cultivated use diameter as the aseptic card punch of 0.5CM at the blade inlet edge place punching subsequent use, move then on pastille PDA plating medium, place in 25 ± 1 ℃ of incubators and cultivate, cultivate and measure colony diameter after 6 days.Every processing repetition 6 times.The result that surveys compare with contrast and calculate antibacterial percentage.5 proportionings are carried out synergism test by the synergism test method.Computing formula is following:
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is following:
Wherein: a, b are respectively 2-cyano-3-amino-3-phenylancryic acetate and own azoles alcohol shared ratio in combination;
A is a 2-cyano-3-amino-3-phenylancryic acetate;
B is own azoles alcohol;
The virulence regression equation of the 2-cyano-3-amino-3-phenylancryic acetate that is obtained, own azoles alcohol and composite comparison rice sheath blight disease, suppress in concentration and synergy ratio (SR) like following table:
The own azoles alcohol of table 1 2-cyano-3-amino-3-phenylancryic acetate is to the rice sheath blight disease Toxicity Determination
Can know by table 1; 2-cyano-3-amino-3-phenylancryic acetate of the present invention and own azoles alcohol are composite; To the rice sheath blight disease Toxicity Determination; When 2-cyano-3-amino-3-phenylancryic acetate and own azoles alcohol proportioning is that 1: 1,4: 1,7: 1,10: 1,13: 1 synergy ratio is respectively 1.35,1.50,1.73,170,1.48, wherein when 2-cyano-3-amino-3-phenylancryic acetate: own azoles alcohol shows as synergistic effect when being 4: 1,7: 1,10: 1, explain 2-cyano-3-amino-3-phenylancryic acetate and own azoles pure both be mixed in the scope at 4: 1～10: 1 comparatively reasonable.
Practice example two: the 2-cyano-3-amino-3-phenylancryic acetate and the composite rice disease test of pesticide effectiveness of preventing and treating of own azoles alcohol
This EE is Changan District Wang Mang township in the Xian City, Shanxi Province, and test medicine is researched and developed, provided by Shaanxi Pucheng County Meibang Pesticide Co., Ltd., contrast medicament 25% 2-cyano-3-amino-3-phenylancryic acetate suspending agent (commercial), 10% own azoles alcohol missible oil (commercial).
