The table shows the zone of inhibition sizes for different disinfectants, which indicates the effectiveness of the disinfectants in inhibiting bacterial growth, not necessarily killing the bacteria. Bactericidal activity (actual killing of bacteria) cannot be determined solely from the zone of inhibition sizes.
