Effect of the preventative application of linear undecapeptides in control of infections in detached pear (P. syringae pv. syringae) and pepper (X. axonopodis pv. vesicatoria) leaves and in immature pear fruits (E. amylovora). Two independent experiments, assay 1 (black bars) and assay 2 (white bars), were performed. A nontreated control (NTC) and a reference treatment with streptomycin (Strep) were used. The confidence intervals for the means are indicated on top of the bars. An asterisk over a bar indicates a significant difference from the nontreated control for a given experiment, according to Tukey's test (P < 0.05).
