Summary of the invention
The purpose of this invention is to provide a kind of bactericidal composition with synergistic effect, realize improving drug effect, reduce the purpose of polluting, reducing labour cost.This bactericidal composition contains tetramycin and two kinds of active ingredients of thifluzamide.
Utilize bactericidal composition of the present invention, be equipped with the known auxiliary agent of those skilled in that art, make formulation of the present invention with those skilled in that art's known method, comprise aqua and suspending agent.
In the above-mentioned bactericidal composition, the weight ratio of tetramycin and thifluzamide is 1:100～50:1.
Above-mentioned bactericidal composition has following characteristics: 1. composition novelty, and pesticide resistance is low; 2. organic principle is not added in formulation environmental protection; 3. two kinds of compositions are composite, and synergistic effect is remarkable; 4. twenty percent does not have cross resistance between dividing; 5. delay the generation of active ingredient resistance, reduce peasant's labour cost.
Embodiment
For determining tetramycin and two kinds of composite synergistic effects of active ingredient of thifluzamide, the applicant at first uses these two kinds of compositions to carry out the indoor biometrics test, and test method and result are as follows:
After at first having analyzed the effect characteristics of two kinds of active ingredients, we will give birth to the object of surveying control and be decided to be rice sheath blight disease, these sick pathogenic bacteria are thanatephorus cucumeris(frank) donk (Thanatephorus cucumeris), this Pseudomonas Basidiomycotina fungi, sclerotium is dark brown, and it is light brown to the taupe mildew that bacterium colony is.
The test method of indoor biometrics: adopt growth rate method to measure medicament to the inhibitory action of rice sheath blight disease mycelia growth.On the basis of preliminary experiment, from each medicament the germ mycelial growth inhibition rate is reached 5 concentration of design in 20%～90% scope, it is standby earlier with the former medicine of 95% tetramycin and the former medicinal methyl alcohol of 95% thifluzamide to be that solvent is made into the soup of series concentration, then with soup in 1% ratio join melt and the PDA medium of cool to room temperature in, after fully shaking up, pour into and make band medicine flat board in the culture dish (Φ 90mm) of sterilization, every processing repeats for four times, to add the blank that is treated to of sterile water; Card punch (Φ 5mm) picking Rhizoctonia solani Kuhn bacterium cake with sterilization, mycelia faces down aseptic inoculation in the central authorities of band medicine flat board, be inverted in 25 ℃ interior cultivation of constant incubator, adopt the right-angled intersection method to measure colony diameter after cultivating 6d, calculate each medicament to the EC50 of pathogen, and calculate toxicity index, the virulence of more different medicaments and bacteriostasis according to the following equation.Used former medicine is tested in above-mentioned living test and reagent is all bought from other producers.
The co-toxicity of mixture preparation adopts the abundant co-toxicity coefficient method representation of Sun Yun:
The theoretical toxicity index TTI=∑ of mixture preparation (the toxicity index ATI of certain medicine * percentage of this pharmaceutically active ingredient in mixture).
Co-toxicity coefficient CTC was synergistic effect greater than 120 o'clock, less than 80 o'clock be antagonism, be addition in the time of between 80～120.
The indoor biometrics test data sees the following form:
Table 1 tetramycin, thifluzamide and different proportioning are to the measurement result of rice sheath blight disease co-toxicity coefficient
By above-mentioned data as can be seen, when tetramycin and thifluzamide are composite in varing proportions, the co-toxicity coefficient (CTC) of prescription is all greater than 120, prevention and control capability to rice sheath blight disease has obvious synergistic effect, and wherein the synergistic effect between 1:5～5:1 of tetramycin and thifluzamide is the most remarkable.
By indoor biometrics verification experimental verification tetramycin and two kinds of active ingredients of thifluzamide are composite good synergistic effect arranged, below by instantiation in order to further describing the present invention, but the present invention absolutely not only only limits to following these embodiment.Percentage all is weight percentage in the prescription, and employed former medicine and auxiliary agent are other producers and buy.
