Resumo: Canker have been found in field plantings of parica examined in Dom Eliseu county, Para State,Brazil. Several fungal species were associated with the field canker, most notably Lasiodiplodia theobromaeand Pestalotiopsis sp. Isolated cultures of these fungi together with other often associated fungi (includingFusarium oxysporum, Alternaria, basidiomycetes) were tested for pathogenicity on young parica plants, withapproximately one meter height. Only L. theobromae produced canker under the conditions tested when discsof culture were applied using wound inoculation techniques and high humidity, which closely mimicked the fieldsymptoms. Pestalotiopsis sp. proved much less damaging compared to L. theobromae. The acknowledgment ofL. theobromae as the causal agent of parica canker came after the reisolations of the fungus from symptomatictissue of inoculated plants, concluding the verification of Koch’s Postulates. This is the first report of thispathogen in paricá.

Várias espécies de fungos foram associadas ao cancro observado no campo, mais notavelmente Lasiodiplodia theobromae e Pestalotiopsis sp. Culturas isoladas destes fungos, frequentemente associados a outros (incluindo Fusarium oxysporum, Alternaria e basidiomicetes), foram testadas quanto à patogenicidade em plantas jovens de paricá, com aproximadamente um metro de altura. Apenas L. theobromae produziu cancro sob as condições testadas, quando discos de cultura foram aplicados usando técnicas de inoculação por ferimento e alta umidade, reproduzindo perfeitamente os sintomas do campo. Pestalotiopsis sp. causou danos muito menores quando comparado a L. theobromae. A confirmação de L. theobromae como agente causal do cancro em paricá ocorreu após o reisolamento do fungo a partir dos tecidos sintomáticos das plantas inoculadas em casa-de-vegetação, concluindo a verificação dos Postulados de Koch. Este é o primeiro relato deste patógeno em paricá. Doi: 10.4336/2009.pfb.59.69Embrapa Florestas2010-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/18Pesquisa Florestal Brasileira; n. 59 (2009): jul./dez.; 69Pesquisa Florestal Brasileira; No. 59 (2009): jul./dez.; 691983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/18/17Tremacoldi, Célia ReginaLunz, Alexandre MehlCosta, Fábio Renato de Souzainfo:eu-repo/semantics/openAccess2017-04-28T14:06:04Zoai:pfb.cnpf.embrapa.br/pfb:article/18Revistahttps://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:2017-04-28T14:06:04Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
