  1. LC50 values for treatments followed by the same letter are not significantly different based on the lethal dose ratio value in which the 95% confidence interval (CI) does not include a value of 1 (P = 0.05).
  2. LC50 lethal dose ratio between AITC and BITC = 3.66 (3.404–3.935).
  3. LC50 lethal dose ratio between AITC and 4HBITC = 0.34 (0.325–0.365).
  4. LC50 lethal dose ratio between BITC and 4HBITC = 0.094 (0.087–0.102).
