Abstract
The invention discloses a sterilization composition containing penflufen and validamycin, wherein the mass ratio of penflufen to validamycin is 20:1-1:20. The sterilization composition has better preventing and curing effects on crop fungous diseases such as rice sheath blight diseases, two medicaments are applied in a matched way, the dosage can be reduced, in addition, the validamycin is biopesticide, the ecological damage and the environment pollution can be effectively reduced in the use process, and in addition, the yield and the quality of crops can be improved. The penflufen and the validamycin in the sterilization composition have low toxicity and are safe to people, livestock and beneficial organisms, and the drug resistance of germs on single medicaments can be delayed.
Description
Technical field
The invention belongs to disinfectant use in agriculture field, be specifically related to the bactericidal composition of a kind of fluorine azoles bacterium aniline and jinggangmeisu.
Background technology
Fluorine azoles bacterium aniline (English common name: penflufen), molecular formula is C18H24FN3O, and structural formula is as follows:
Chemistry adopted name is N-[2-(1,3-dimethylbutyl) phenyl]-5-is fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide, this bactericide is succinate dehydrogenase (SDH) inhibitor, Main Function transmits Complex II in respiratory chain electronics, blocking-up energy metabolism.Seed after treatment can absorb fluorine azoles bacterium aniline in germination process, and by xylem, is transmitted to other positions of plant corpus, thereby plays the effect of cover crop.It is mainly used in seed treatment, the effective disease such as control rust, stalk break, root rot, smut and powdery mildew, can be composite with prothioconazoles, metalaxyl, clothianidin, oxime bacterium ester etc., not only can prevention and elimination of disease and pests, can also delaying drug resistance produce and development.
Jinggangmeisu (English common name: Validamycin), molecular formula is C20H35O13N, and structural formula is as follows:
Chemistry adopted name is N-((1S)-(Isosorbide-5-Nitrae, 6/5)-3-methylol-4,5,6-trihydroxy-2-cyclohexenyl group)-(O-β-D-glycopyranosyl-(1 → 3)-(1S)-(1,2,4/3,5)-2,3,4-trihydroxy-5-Hydroxymethylcycloheamines amines, it is the antibiotic that a kind of actinomycetes produce, there is stronger interior absorption, easily by somatic cells, absorbed and conduction rapidly within it, disturb and inhibition somatic cells g and D.Sterling is white unformed powder, and water-soluble, dimethyl formamide, is slightly soluble in ethanol, be insoluble to acetone, benzene, ethyl acetate, etc. organic solvent, hygroscopicity is strong, stable in the room temperature PH3-9 aqueous solution.Be mainly used in rice sheath blight disease, also can be used for the crop pests such as rice green smut, corn northern and southern leaf blight and vegetables and cotton, beans, have preventive effect high, without poisoning, the plurality of advantages such as pollution-free.
Summary of the invention
When fluorine azoles bacterium aniline and jinggangmeisu single dose are used separately, cause germ easily to produce resistance variation, cause the preventive effect of medicament to reduce even invalid problem, the present invention proposes a kind of new type bactericide composition.The present invention is by fluorine azoles bacterium aniline and the two combination of jinggangmeisu, there is in actual use bactericidal activity high, and two class medicaments possess different structure types and discrepant mechanism of action, the two combination can delay the generation of pathogen pesticide resistance and development to a greater extent, and dosage total in unit are is declined, thereby realize object economic, efficient, environmental protection.
Technical scheme of the present invention is as follows:
A bactericidal composition for fluorine-containing azoles bacterium aniline and jinggangmeisu, wherein the mass ratio of active ingredient fluorine azoles bacterium aniline and jinggangmeisu is 20:1～1:20.
In described bactericidal composition, the mass ratio of fluorine azoles bacterium aniline and jinggangmeisu is preferably 10:1～1:10, more preferably 1:5～1:10.
In described bactericidal composition, be added with the upper conventional bactericide auxiliary agent of agricultural and can be made into the common pesticides formulations such as aqueous suspension agent, wetting powder, water dispersible granules.The agricultural bactericidal agent aid adopting comprises each analog assistants such as wetting agent, dispersant, thickener, defoamer, antifreezing agent, filler, the wetting agent adopting, dispersant be in dispersing agent MF, sodium lignin sulfonate, calcium lignosulfonate, neopelex, calcium dodecyl benzene sulfonate, sodium butylnaphthalenesulfonate, alkylphenol polyoxyethylene, castor oil polyoxyethylene ether etc. one or more, the thickener that adopts is one or both in xanthans, sodium alginate; The defoamer adopting be in tributyl phosphate and silicone defoaming agent one or both; The antifreezing agent adopting is one or more in ethylene glycol, propane diols and urea; The filler adopting is one or more in white carbon, kaolin, attapulgite etc.;
Described bactericidal composition, the active ingredient that preferred fluorine azoles bacterium aniline and jinggangmeisu form accounts for 10%～55% of bactericidal composition gross mass.
The application of described bactericidal composition in preventing and treating the crop fungal diseases such as rice sheath blight disease.
By the careful analysis to fluorine azoles bacterium aniline and jinggangmeisu sterilization idiocratic, use Wadley method to carry out experimental scheme and result treatment, first measure the EC of fluorine azoles bacterium aniline and jinggangmeisu two single compounds (hereinafter to be referred as medicament)
50, according to the EC of two single medicaments
50by Wadley method, set the portfolio ratio of two medicaments, and according to Wadley synergy index SR value, determine suitable composition ratio, then by the abundant method of Sun Yun, verified.
Test objective thing is Rhizoctonia solani Kuhn.Test adopts colony diameter method.Get fluorine azoles bacterium aniline, jinggangmeisu mother liquor, be configured to need liquid dull and stereotyped, the about 14ml of every ware arranges without the dull and stereotyped contrast of medicine (CK) simultaneously, and every processing repeats 3 wares, repeats 3 times.At preculture colony edge, with the card punch of sterilizing, produce the mycelia piece of 5mm diameter, move on to respectively on different culture media flat board, cultivate 2d for 28 ℃, measure colony diameter (mm), by following formula, calculate growth inhibition ratio:
Mycelial growth inhibition rate is converted into and suppresses probit value (Y), drug concentration is converted into concentration logarithm (X), by concentration logarithm, be that abscissa, probit value are that ordinate is made toxicity regression straight line, try to achieve fluorine azoles bacterium aniline and jinggangmeisu single dose and the virulence regression equation of mixture to Rhizoctonia solani Kuhn thereof, and calculate EC
50, EC
90value and correlation coefficient r value.
According to the interaction of Wadley method evaluation mixture, computing formula is as follows:
EC
50 (theoretical values)=(a+b)/(a/EC
50a+ b/EC
50b), SR=EC
50 (theoretical values)/ EC
50 (real values).
Wherein a, b are each component content ratio in mixture, the effect being mixed with the analysis of SR value.SR≤0.5, two kinds of medicaments antagonism that has been mixed; SR=0.5～1.5, two kinds of medicaments addition that has been mixed; SR >=1.5, two kinds of medicaments synergistic effect that has been mixed.
Table 1 fluorine azoles bacterium aniline and jinggangmeisu single dose and mixture thereof are to rice sheath blight disease toxicity test result
From table 1, data can be analyzed and obtain, fluorine azoles bacterium aniline and jinggangmeisu can suppress the growth of rice sheath blight disease mycelia while being mixed with 15:1～1:15 ratio, with 1:5,1:10 and 1:15 ratio, be mixed, can suppress more by force the growth of rice sheath blight disease mycelia, synergistic effect is remarkable.
The present invention has good control efficiency to crop fungal diseases such as paddy rice, and two medicament fit applications, can reduce dosage, effectively reduce ecological disruption and environmental pollution, and can improve crop yield and quality; In the present invention, fluorine azoles bacterium aniline and jinggangmeisu all belong to the toxicity such as low, and jinggangmeisu is biopesticide, to people and animals, beneficial organism safety; Can delay the pesticide resistance of germ to single medicament.
