[0055] Example
[0056] (1) Bioassay for synergistic effect
[0057] The Sun Y-P method is used to calculate the co-toxicity coefficient (CTC) to evaluate the mixing effect of the two active ingredients in the pesticide composition of the present invention, as follows:
[0058] Evaluation criteria: when CTC≥120, it shows synergistic effect; when CTC≤80, it shows antagonism; 80
[0059] Calculation formula:
[0060] Co-toxicity coefficient (CTC)=[Actual toxicity index of the mixture (ATI) / Theoretical toxicity index of the mixture (TTI)]×100
[0061] The actual toxicity index of the mixture (ATI) = (LC of the standard agent 50 / Mixed LC 50 )×100
[0062] Theoretical Toxicity Index (TTI) of the mixture = TI of agent A × content of A in the active ingredient of the mixture + TI of agent B × content of B in the effective ingredient of the mixture
[0063] Toxicity Index (TI) = (LC of standard medicine 50 / LC of test agent 50 )×100 (use one of A and B as the standa...
