Resumo: http://dx.doi.org/10.5902/1980509818445The root-rot of  erva-mate, caused for Fusarium spp., Rhizoctonia sp. and Pythium sp., is the main disease of the culture and causes serious damages in nurseries and forest stands. However, few studies exist regarding to the epidemiology of this disease. Thus, the present work studied and described the main epidemic aspects related to erva-mate root-rot in nurseries and forest stands. For that, nurseries and forest stands were chosen for studies in Vale do Taquari, RS state, where flowers, fruits, seeds, plantlets, seedlings and soil were collected for laboratory analyses. It was observed that the pathogens can enter in the patho-system through the flowers, because 80% of them presented contamination of Fusarium sp. and 15% of Rhizoctonia sp. Moreover, the obtaining method and stratification of the seeds, used in the nurseries, contribute to the increase of contamination, reaching 100% of the seeds in the moment of sowing. It was also observed that contaminated seedlings may be symptomless and, after transplanting in the field, contaminate pathogen free areas. Pathogenicity tests with some isolates showed their capacity of causing the disease.

No entanto, existem poucos estudos referentes à epidemiologia dessa doença. Assim, o presente trabalho teve por objetivo estudar e descrever os principais aspectos epidemiológicos relacionados à podridão-de-raízes da erva-mate em viveiro e a campo. Para isso, foram demarcados para estudo ervais e viveiros localizados na região alta do Vale do Taquari - RS, nos quais se procedeu a coleta de flores, frutos, sementes, plântulas, mudas e substrato para análises laboratoriais. Observou-se que as flores podem ser a porta de entrada dos patógenos no patossistema, pois 80% delas apresentaram contaminação por Fusarium sp. e 15% por Rhizoctonia sp. Além disso, o método de obtenção e estratificação das sementes, utilizado pelos viveiristas, contribuem para o aumento da contaminação, chegando a 100% das sementes no momento da semeadura. Observou-se, também, que as mudas podem estar contaminadas, mesmo não apresentando sintomas e, ao serem replantadas a campo, venham a contaminar áreas livres dos patógenos. Os testes de patogenicidade com alguns isolados mostraram sua capacidade em causar a doença.Universidade Federal de Santa Maria2015-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1844510.5902/1980509818445Ciência Florestal; Vol. 25 No. 2 (2015); 281-291Ciência Florestal; v. 25 n. 2 (2015); 281-2911980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/18445/10844Poletto, IgorMuniz, Marlove Fátima BriãoCeconi, Denise EsterPoletto, Talesinfo:eu-repo/semantics/openAccess2018-09-12T13:36:29Zoai:ojs.pkp.sfu.ca:article/18445Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-09-12T13:36:29Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
