Resumo: 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.

Quatro isolados de P. palmivora e 15 de Fusarium spp. foram inoculados em caules com ferimentos, usando-se um disco de micélio-ágar como inóculo. A avaliação consistiu naobservação dos sintomas de amarelecimento e morte da folha bandeira e folhas externas. Os resultados mostraram que P. palmivora causou danos mais severos do que Fusarium spp, e que ocorrem diferenças na agressividade dos isolados desses patógenos.Embrapa Florestas2011-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/218Pesquisa Florestal Brasileira; n. 52 (2006): jan./jun.; 133Pesquisa Florestal Brasileira; No. 52 (2006): jan./jun.; 1331983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/218/169Alves, Sandro Alex RosaSantos, Álvaro Figueredo dosTessmann, Dauri JoséVida, João Batistainfo:eu-repo/semantics/openAccess2021-03-19T21:48:10Zoai:pfb.cnpf.embrapa.br/pfb:article/218Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2021-03-19T21:48:10Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
