Impacts of smRLs on necrosis symptoms caused by B. cinerea on tomato leaves. Plants were sprayed with 300 µM of smRLs, natural rhamnolipid mix (Rha) or DMSO 0.1% and 3 days later, detached leaves were inoculated with the fungus. Necrosis diameter measures (a) 72 hai; (b) 96 hai. Values shown are means +/− SD of three independent repetitions (each repetition was realized in triplicate and each replicate consisted of four leaves). Different lower-case letters indicate significant differences between the treatments, as determined by an ANOVA followed by the Tukey-HSD post-hoc test (p ≤ 0.05).
