Fusarium spp. and Phytophthora palmivora isolates associated with basal stem rotting of peach palm

The objective of this research was to evaluate the pathogenicity of P. palmivora and Fusarium spp. isolates associated with basal stem rotting of peach palm. Four P. palmivora isolates and 15 Fusarium spp. isolates were inoculated in wounded stems using mycelial plugs as inoculum. Disease intensity was based on symptoms showed by leaf flags and full- xpanded leaves, which ranged from yellowing to necrosis. It was verified that P. palmivora caused more damage than the Fusarium spp., and that the isolates of these fungi presented variation on aggressiveness.
