Resumo: Castor bean (Ricinus communis L.) is susceptible to more than 150 different microorganisms and is affected by several diseases some of which responsible for great economic harms. The purpose of this study was to detect seed-transmitted fungi and to identify those pathogenics to this crop. It was made seed health analysis and pathogenicity studies with the microorganisms detected under laboratory conditions, in Campina Grande, PB, Brazil. Several fungi were detected in castor seed. Some are causal agents of serious plant diseases. Fusarium sp., Alternaria ricini, Aspergillus flavus and Chaetomium sp. caused seed rot and or lower germination. Fusarium sp., Rhizoctonia solani and Alternaria ricini were transmitted by seed and caused severe seedling damping-off.

Este trabalho teve como objetivo detectar fungos transmitidos pela semente e identificar os patogênicos a essa cultura. Foram realizadas análises sanitárias de sementes e testes de patogenicidade com os microrganismos detectados, em condições de laboratório, em Campina Grande, PB. Diversos fungos foram detectados na semente, alguns deles causadores de doenças em várias culturas. Entre os fungos isolados, Fusarium sp., Alternaria ricini, Aspergillus flavus e Chaetomium sp. causam podridão da semente e afetam seu poder germinativo; Fusarium sp., Rhizoctonia solani e Alternaria ricini são transmitidos pela semente, causando tombamento das plântulas e sérios danos à cultura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLima, Emídio FerreiraBatista, Fernando Antônio SoutoSantos, José Wellington dos1997-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4740Pesquisa Agropecuaria Brasileira; v.32, n.9, set. 1997; 915-918Pesquisa Agropecuária Brasileira; v.32, n.9, set. 1997; 915-9181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4740/7300info:eu-repo/semantics/openAccess2015-03-18T19:32:02Zoai:ojs.seer.sct.embrapa.br:article/4740Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-18T19:32:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
