Fig. 1. Enhanced resistance of cucumber plants against powdery mildew disease by exogenous salicylic acid (SA) treatment. (A, B) Powdery mildew disease symptom developed 7 days after inoculation. Before the pathogen inoculation, cucumber plants were sprayed with steriled tap water (A) or 1 mM SA (B). (C–F) Disease control effect of SA. (C, D) Cucumber leaves developing powdery mildew disease symptoms before the SA treatment. (E, F) Disease progression was observed 7 days after spray with steriled tap water (E) or 1 mM SA (F). SA effectively suppressed new infection (B) and disease progression (F) in cucumber plants.
