Data recorded 60 days after bacterial treatment. Disease severity was assessed on a scale of 1 to 5 (1, symptoms free; 5, severe symptoms). Same letters within each column represent non-significant difference at 5%, according to Duncan’s tests using the GLM procedure (df = 11, F = 3.63, and p < 0.05).
