Fire blight symptoms in pear leaves submitted to different treatments with lysozyme and BP100. a Wounded leaves were treated with 10 μl of either, water (NTC), BP100 at 100 μM, lysozyme, or BP100 at 25 μM combined with lysozyme. Then, wounds were inoculated with 10 μl of a suspension of E. amylovora EPS101 at 107 UFC/ml. Assessment of symptoms was performed after 5 days of incubation at 23 °C under high relative humidity. b Scale of severity of infections according to the symptoms observed: 0, no symptoms; 1, leaf necrosis localized around the wound; 2, necrosis progression far from the wound; and 3, necrosis extended to most part of the whole leaf
