Figure 13. Activity of non-volatile metabolites produced by endophytic strains against
Phyllosticta citricarpa 14 days after inoculation with a) 5 mg of fungicide glyphosate
(Positive control); the strains b) LGMF1133 (Nigrospora sp.), c) LGMF1121
(Nigrospora sp.) and d) LGMF1119 (Xylariaceae 1); e) Water (Negative control).

non-volatile and volatile metabolites produced by three endophytic
isolates from Vochysia divergens

Treatment Non-volatile Volatile

phytopathogen LGMF06 plus the fungicide glyphosate (50 mg/mL).
