Resumo: In 2004, some plantations of Ilex paraguariensis A. St.-Hil. In Taquari Valley, state of Rio Grande do Sul, started presenting growth stagnation, yellowing, leaf drop and necrosis in the root system, typical symptoms of root rot. Roots samples were collected in farms of two cities and sent for analysis at the Plant Disease Laboratory at the Department of Plant Protection/CCR/UFSM. The presence of Rhizoctonia and Pythium was diagnosed and these were pathogenic when inoculated in plants of erva-mate. This is the first observation of these two fungi causing root rot in erva-mate plantations in the state of Rio Grande do Sul, Brasil.

St.-Hil.) do Vale do Taquari, RS, apresentaram estagnação do crescimento, amarelecimento, queda de folhas e necrose no sistema radicular, sintomas típicos da podridão-de-raízes. Amostras de raízes de plantas foram coletadas, em propriedades dos municípios de Ilópolis e Putinga, e enviadas ao Laboratório de Fitopatologia do Departamento de Defesa Sanitária/CCR/UFSM para análise fitopatológica. Foi constatada a presença de fungos dos gêneros Rhizoctonia e Pythium e estes se mostraram patogênicos quando inoculados em plantas de erva-mate. É a primeira constatação desses dois fungos causando podridão-de-raízes em ervais no estado do Rio Grande do Sul, Brasil.Universidade Federal de Santa Maria2007-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/193610.5902/198050981936Ciência Florestal; Vol. 17 No. 1 (2007); 65-69Ciência Florestal; v. 17 n. 1 (2007); 65-691980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1936/1178Poletto, IgorMuniz, Marlove Fátima BriãoCeconi, Denise EsterWeber, Maria Nevis DecontoBlume, Elenainfo:eu-repo/semantics/openAccess2017-05-12T18:16:32Zoai:ojs.pkp.sfu.ca:article/1936Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-12T18:16:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
