Percentage of barrier efficiency (number of individuals failing to reach the red post divided by the total number of individuals, multiplied by 100) of each treatment for the four snail species. The percentage of negative control and dry garlic treatments have been tested twice. The percentage displayed on the graph for these treatments corresponds to the average efficiency of the dry and wet barrier tests.
