Fig 1. Survival percentage of Bursaphelenchus sp. isolates (high virulence B. xylophilus Ka4 and B. xylophilus T4, and low virulence B. xylophilus C14-5 and B. mucronatus Un1) after 24 hours exposition to H₂O₂ conditions (H₂O₂ concentrations ranging from 0 to 40 mM).

Error bars represent standard deviation. Different letters above the columns indicate significant differences (p < 0.05) between Bursaphelenchus sp. isolates survival percentages in each H₂O₂ treatment, according to post-hoc Duncan’s test.
