Indoor virulence determination of kasugamycin and quinolinone against citrus canker:
Kasugamycin and quinolinone are two bactericides with different structures and mechanisms, and the purpose of measuring the combined effect of the two bactericides on the citrus canker is to determine the combined effect of the two bactericides.
The test method comprises the following steps: dissolving two original drugs of kasugamycin and quinolinone by acetone, respectively diluting by Tween-80 sterile water containing kasugamycin with the test concentration of 1, 5, 10, 20 and 50mg/L, quinolinone with the test concentration of 5, 10, 20, 50 and 100mg/L and 0.05 percent of kasugamycin and quinolinone, and preparing the mixed test concentrations of 5, 10, 20 and 50mg/L, 7:5, 11:5 and 11:3 into 100, 50 and 10mg/L according to the mass ratio of 1:20, 1:15, 1:11 and 5: 7.
Medicament treatment: the method for measuring the indoor bacteriostatic effect comprises the following steps: the growth rate method is adopted to determine the inhibition effect of the bactericidal composition on citrus canker pathogens. Taking hypha blocks with the diameter of 5mm from the edge of the citrus canker cultured on the PDA culture medium for 4 days, respectively inoculating the hypha blocks to PDA culture medium plates containing bactericides with different concentrations, culturing at constant temperature of 28 ℃, taking the plate without the medicament as a blank control, measuring the diameter of each treated colony after 4 days, and calculating the inhibition percentage of the medicament on the growth of the hypha. Regression analysis is carried out through logarithm of each treatment dosage and probability value of hypha growth inhibition rate, the inhibition medium concentration (EC50) of the treatment bactericide on the citrus canker is calculated, and the cotoxicity coefficient (CTC) is calculated according to the Sun cloud Peel method.
Data statistical analysis: calculating and correcting the mortality rate according to Abb0tt disclosure, solving a virulence regression equation by using a mortality-probability value and a concentration logarithm value, calculating the lethal middle concentration LC50 (mg/L) of each single dose and the proportion thereof, and evaluating the virulence strength of the kasugamycin and quinolinone mixture on citrus canker.
Relative virulence index (TI) = LC50 of control agent/treatment agent LC50 × 100
Actual virulence index (ATC) = LC50 of control agent/mixed agent LC50 × 100
Theoretical virulence index (TTI) = virulence index of pesticide a × a% + virulence index of pesticide B × B%
Cotoxicity coefficient (CTC) = (ATC/TTI) × 100
If the co-toxicity coefficient CTC of the mixture is more than or equal to 120, the synergistic effect is shown; if the CTC is less than or equal to 80, the antagonism is shown; for example 80 < CTC < 120, indicating that the two are combined to act similarly.
