Middle cultivation.
Taking out culture medium flat plate after 3 days, measure each process colony diameter by decussation method, the mycelia calculating each process is raw
Long suppression ratio.Logarithm value according to drug concentration (mg/L) is independent variable x, with the probit value of corrected mortality for dependent variable y, point
Do not set up virulence regression equation formula, use DPS computed in software single dose and the EC of each proportioning mixture50And mixture co-toxicity coefficient.Altogether
Poison coefficient (CTC) >=120 shows as potentiation；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficients
(CTC) ＜ 120 shows as summation action.Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100。
Theoretical toxicity index (TTI)=(percentage composition of A in the toxicity index × mixture of A)+(in the toxicity index × mixture of B the hundred of B
Divide content).Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] × 100.
