Resumo: Seven isolates of Pyricularia sp fungus were inoculated from other grasses on rice cultivars differentiating from physiologic races of P. oryzae, in order to determine the compatibility between rice plants (Oryzae sativa L.) and the fungus found in other hosts. The results obtained showed that three isolates of Pyricularia from crabgrass (Digitaria sanguinalis (L.) Scop.), barnyard grass (Echinochloa spp.) and rice cutgrass (Leersia hexandra Sw.), respectively, were pathogenic to rice plants. Four other isolates from Paspalum sp (two) and rice cutgrass (Leersia hexandra) (two) did not infect the rice cultivars when inoculated. Based on these results, it was concluded that some isolates, besides having compatibility with rice plants, showed pathogenic variability. These factors indicate the possible dissemination of the fungus to the rice plants through intermediate hosts.

Os resultados obtidos mostraram que três isolados de Pyricularia, a partir de milhã (Digitaria sanguinalis (L.) Scop.), capim-arroz (Echinochloa spp.) e grama-boiadeira (Leersia hexandra Sw.), respectivamente, foram patogênicos ao arroz. Quatro isolados de: Paspalum sp (dois) e de grama-boiadeira (L. hexandra) (dois), não atacaram as cultivares de arroz inoculadas. Concluiu-se que, além de existir compatibilidade de alguns desses isolados com plantas de arroz, o fungo apresenta variabilidade patogênica, existindo a possibilidade de ele se disseminar para o arroz a partir de hospedeiros intermediários.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRibeiro, Alceu Sallaberry2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16851Pesquisa Agropecuaria Brasileira; v.16, n.2, fev. 1981; 209-212Pesquisa Agropecuária Brasileira; v.16, n.2, fev. 1981; 209-2121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16851/11179info:eu-repo/semantics/openAccess2014-04-15T19:39:04Zoai:ojs.seer.sct.embrapa.br:article/16851Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:39:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
