Compliance test result
1、Indoor bioassay embodiment
Using NY/T1156.16-2008 bacterial turbidities method to determine different compound proportion medicaments, (for I for thiophene bacterium cyclopentadienyl, II is amber glue
Adipic acid copper) to the inhibiting rate of citrus bacterial canker disease germ.
1.1 citrus bacterial canker disease germs cultivate 48h before measure on solid medium, and single bacterium colony is inoculated in into liquid training
Support in base and cultivate 12h, the bacterial suspension that transmissometer display numeral is 300NTU is configured to sterilized water.Each addition medicament
Triangular flask is inoculated with 20 μ L bacterium solutions, and at 28 DEG C, 150rpm vibrations are lower to cultivate.
1.2 treat that CK turbidity reaches 400-600NTU, start to handle the turbid of culture with transmissometer measurement different agents concentration
Degree.Bacterial growth inhibiting rate (%), expected inhibiting rate (%), toxic effect ratio are calculated by formula.
Bacterial growth inhibiting rate (%)=100 × (blank control turbidity value added-medicament turbidity value added)/blank
Compare turbidity value added
It is expected that inhibiting rate=I medicaments EC50It is worth actual inhibiting rate × I medicament proportion+II medicaments EC50Value is actual to be suppressed
Rate × II medicament proportions
Toxic effect ratio=actual inhibiting rate/expection inhibiting rate
Toxic effect ratio criterion：Toxic effect ratio>1.25 be synergistic effect, and ﹤ 0.75 is antagonism, 0.75≤toxic effect ratio
Rate≤1.25 are summation action.
By the linear regression analysis between the probit value (Y) of Bacteria suppression rate and the logarithm value (X) of serial drug concentration,
Obtain the EC of each single dose50Value.Make regression analysis and correlation analysis with SPSS data processing softwares, calculate each single dose medicament
EC50, coefficient correlation etc..
1.3 thiophene bacterium cyclopentadienyl, tiger glue adipic acid copper single dose have certain bacteriostatic activity, bacteriostatic activity examination to citrus bacterial canker disease germ
Test and the results are shown in Table 1.
The thiophene bacterium of table 1 cyclopentadienyl, tiger glue adipic acid copper are to the Antibacterial Activity of citrus bacterial canker disease germ
1.4 different compound proportion medicaments are shown in Table 2 to the inhibiting rate of citrus processing.
Antibacterial Activity of the different compound proportion medicaments of table 2 to citrus bacterial canker disease germ
As shown in Table 2, when thiophene bacterium cyclopentadienyl and tiger glue adipic acid copper mass ratio are 1：When 1.1, actual inhibiting rate and toxic effect ratio
Equal highest, respectively 84.5% and 1.485；Secondly mixed proportion is 1：When 0.8, actual inhibiting rate and toxic effect ratio are respectively
78.7% and 1.424.In addition, two compound proportions 1：1.7 and 1：2.6 test group, its toxic effect ratio are similar to 1.2, close to increasing
Effect effect ratio (1.25), in practical application, the factor such as comprehensive auxiliary material, formulation, can generally also show preferably to suppress effect
Fruit.
Although above the present invention is described in detail with a general description of the specific embodiments,
On the basis of the present invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Cause
This, these modifications or improvements, belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
