In a further embodiment, the weight ratio of described S-Ethyl ethylthio sulfonate and Tebuconazole is (1:6) ~ (3:1).Described auxiliary material comprises dispersant, emulsifier, wetting agent, filler or solvent.Described dispersant comprises NNO, lignosulfonates, naphthalene sulfonate and polymeric carboxylic salt; Described emulsifier comprises phenethyl phenol polyethenoxy ether phosphate, polyoxyethylene nonylphenol ether, Nongru-700 # and agriculture breast 2201; Described wetting agent comprises alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, alkylphenol-polyethenoxy base ether phosphate, alkylsulfonate, alkyl sulfate and methoxyl group fatty acid amido benzene sulfonate; Described filler comprises bentonite, kaolin, aluminium-magnesium silicate and water; Described solvent comprises dimethylbenzene, solvent naphtha and toluene.
The above-mentioned Recompounded pesticide containing S-Ethyl ethylthio sulfonate and Tebuconazole is preventing and treating the application in the water prevention rice bakanae disease.Concrete, every mu of consumption of Tebuconazole is 0.5 ~ 10 gram, every mu of consumption of S-Ethyl ethylthio sulfonate is 1 ~ 6 gram.
Beneficial effect: the present invention effectively can overcome the pesticide resistance of fusarium moniliforme to carbendazim and Prochloraz and endanger, and Tebuconazole and S-Ethyl ethylthio sulfonate is composite has obvious synergistic effect, particularly when Tebuconazole and S-Ethyl ethylthio sulfonate assembly ratio are 1:1,1:2, during 1:3, three combination coefficient of synergism are all greater than 1.5, the synergistic effect that equal tool is good, wherein (Tebuconazole: S-Ethyl ethylthio sulfonate) reaches 2.64 for its coefficient of synergism during 1:3, and synergistic effect is the most obvious.
Embodiment
For the problem of fusarium moniliforme to the medicine resistance of Prochloraz, study a kind of new agricultural chemicals, to reduce the loss causing rice yield due to bakanae disease.This agricultural chemicals is mainly containing Tebuconazole and S-Ethyl ethylthio sulfonate, and wherein Tebuconazole scale every mu of consumption is 0.5-10 gram, S-Ethyl ethylthio sulfonate scale every mu of consumption is 1-6 gram.When preparing concrete medicament, Tebuconazole, S-Ethyl ethylthio sulfonate and known auxiliary agent and excipient are re-dubbed any one formulation that agricultural chemicals allows.These known auxiliary agents and excipient comprise: dispersant, emulsifier, wetting agent, filler, solvent.Dispersant can be: NNO, lignosulfonates, naphthalene sulfonate or polymeric carboxylic salt.Emulsifier can be phenethyl phenol polyethenoxy ether phosphate, polyoxyethylene nonylphenol ether, Nongru-700 # or agriculture breast 2201.Wetting agent can be the compounds such as alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, alkylphenol-polyethenoxy base ether phosphate, alkylsulfonate, alkyl sulfate, methoxyl group fatty acid amido benzene sulfonate.Filler can be bentonite, kaolin, aluminium-magnesium silicate or water.Solvent can be dimethylbenzene, solvent naphtha, toluene etc.
Tebuconazole and S-Ethyl ethylthio sulfonate composite to fusarium moniliforme Toxicity Determination method and result as follows.
Material is: the 80% former medicine Henan the earth agrochemical Co., Ltd of S-Ethyl ethylthio sulfonate provides, 43% Tebuconazole (commercially available).Strains tested is that by Zhenjiang, Hilly area of Jiangsu Province, Jurong is picked up from by plant protection research department of the institute of agricultural sciences to Prochloraz tool pesticide resistance fusarium moniliforme, to be separated to obtain with PDA medium through conventional tissue isolation, saves backup after purified, qualification.
Tebuconazole and S-Ethyl ethylthio sulfonate sterile water are mixed with 10000 μ g/ml mother liquors, mother liquor active ingredient (S-Ethyl ethylthio sulfonate: Tebuconazole) mixes by the mass ratio of 1:1,1:2,1:3,3:2,3:1, is: 200,100,50,25,12.5,6.25,3.125,1.5625 μ g/ml with sterile water by S-Ethyl ethylthio sulfonate dilution.5 mixture combination dilutions are that 5,1.25,0.625,0.3125,0.15625,0.078125,0.0390625 μ g/ml series concentration pastille PSA is dull and stereotyped.Tebuconazole single dose makes the PSA culture medium flat plate of pastille 20,10,5,2.5,1.25,0.625,0.3125,0.15625 μ g/ml.Blank is made, each process repetition 4 times with sterile water.
Mycelial growth rate is adopted to suppress method mensuration single dose and compound drug to the effect of fusarium moniliforme mycelial growth.The Fusarium moniliforme Sheld sheet being about to obtain along colony edge punching amplexiforms on the medium containing medicament, cultivates 5-6 days for 25 DEG C, measures the middle colony diameter of contrast and pastille medium, calculate inhibiting rate.
By DPS 13.0 professional version data handling system, calculate regression equation, EC50 and 95% confidence limit thereof that medicament suppresses fusarium moniliforme mycelial growth.Calculate virulence regression equation and correlation coefficient.Ask the EC50 of each medicament according to regression equation, by Wadley method, calculate coefficient of synergism (SR) and accordingly compound drug synergistic effect evaluated.(SR >=1.5 are synergy, and 0.5<SR<1 is summation action, and SR≤0.5 is antagonism).Wherein, PA, PB are S-Ethyl ethylthio sulfonate, Tebuconazole two component percentage composition in mixture to the EC50 theoretical value X1=[(PA+PB)/(PA/CA+PB/CB)] × 100% of mixture respectively.CA, CB are the EC50 of 2 components in mixture respectively.In the coefficient of synergism SR=X1/X2 formula of mixture, SR is coefficient of synergism, and X1 is the EC50 measured value of the EC50 theoretical value of mixture, X2 mixture.
Result of the test is as following table.From following table, S-Ethyl ethylthio sulfonate and Tebuconazole composite, compound drug synergistic effect when two component ratios are 1:3 is the most obvious, and its coefficient of synergism reaches 2.61.
As can be seen from the above table, Tebuconazole and S-Ethyl ethylthio sulfonate is composite has obvious synergistic effect, when Tebuconazole and S-Ethyl ethylthio sulfonate assembly ratio are 1:1,1:2, during 1:3, three combination coefficient of synergism are all greater than 1.5, the synergistic effect that equal tool is good, wherein (Tebuconazole: S-Ethyl ethylthio sulfonate) reaches 2.64 for its coefficient of synergism during 1:3, and synergistic effect is the most obvious.
