Resumo: | Basal stem rotting (BSR), caused by Fusarium spp., has been observed in peach palm (Bactris gasipaes Kunth. var. gasipaes Henderson) plantations in Brazil since 2000. The disease is a limiting factor to peach palm farming, damaging plants of different ages. The pathogen presence has been verified in seeds. The objectives of this study were: to evaluate the sanitary and physiological quality of eight commercial lots of peach palm seeds from Porto Velho, state of Rondonia, in Brazil; to compare two detection methods for Fusarium spp. in peach palm seeds; to evaluate pathogenicity and to compare aggressiveness of Fusarium spp. isolates from peach palm seeds; and to evaluate the chemical treatment of two peach palm seed lots for controlling Fusarium spp., about their effects on: a) sanitary effect; b) germination and vigor. The Fusarium spp. pathogenic may be transmitted by seeds to seedlings causing BSR disease. The paperboard methodology for Fusarium spp. detection proved to be more efficient for recovering this pathogen in peach palm seeds. The Chlorothalonil + Thiophanate Methyl and Thiophanate Methyl fungicides achieved the effective control over the target pathogen Fusarium spp. in peach palm seeds. Fusarium oxysporum and Fusarium proliferatum isolated from seed and seedling, respectively, were pathogenic to peach palm |

Fusarium oxysporum and Fusarium proliferatum isolated from seed and seedling, respectively, were pathogenic to peach palmDesde o ano 2000 é verificada a ocorrência da doença podridão da base do estipe (PBE), causada por Fusarium spp., em plantios de pupunheira (Bactris gasipaes Kunth. var. gasipaes Henderson). A PBE pode se tornar limitante para o cultivo da pupunheira, ocorrendo em plantas com diferentes idades. Tem-se verificado a presença do patógeno em sementes. Os objetivos deste trabalho foram: avaliar a qualidade sanitária e fisiológica de oito lotes comerciais de sementes de pupunheira provenientes da região de Porto Velho - RO; avaliar dois métodos de detecção de Fusarium spp. em sementes; avaliar a patogenicidade e agressividade de isolados de Fusarium spp. obtidos de sementes ; avaliar o tratamento químico de dois lotes de sementes de pupunheira para o controle de Fusarium spp. Houve grande variação entre os lotes de sementes de pupunheira quanto à germinação, vigor e emergência de plântulas. Fusarium spp. pode ser transmitido das sementes para plântulas causando a doença PBE. A metodologia do papel-cartão para detecção de Fusarium spp. mostrou-se mais eficaz na recuperação deste patógeno em sementes de pupunheira. Os fungicidas tiofanato metílico+clorotalonil e tiofanato metílico controlaram Fusarium spp. em sementes de pupunheira. Fusarium oxysporum e Fusarium proliferatum, isolados de semente e plântula, respectivamente, foram patogênicos à pupunheira.Universidade Federal de Santa Maria2016-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2502910.5902/1980509825029Ciência Florestal; Vol. 26 No. 4 (2016); 1119-1131Ciência Florestal; v. 26 n. 4 (2016); 1119-11311980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/25029/pdfCopyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessda Costa Junior, José Carlosdos Santos, Alvaro FigueredoFranciscon, Luzianeda Silva, Cleiltan NovaisTessmann, Dauri José2017-04-05T14:25:07Zoai:ojs.pkp.sfu.ca:article/25029Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-05T14:25:07Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
