Effect of the preventive application of BP100 and lysozyme in the control of E. amylovora infections on pear leaves. BP100 was applied at different concentrations, alone or combined with lysozyme, in detached pear leaves, just 1 h before the inoculation with a suspension of E. amylovora (108 CFU/ml). Nontreated control (NTC), lysozyme control and reference treatment with streptomycin were included. Four independent experiments (a, b, c and d) were performed. The confidence intervals for the means are indicated on top of the bars. Different letters over a bar indicate a significant difference from the nontreated control for a given experiment, according to Waller-Duncan's test (P < 0.05)
