Resumo: Dicyma pulvinata is an efficient biocontrol agent of Microcyclus ulei, causal agent of South American leaf blight. The objective of this work was to obtain strongly antagonistic isolates. A survey was carried out in rubber plantations located in 14 municipalities in the Sates of Acre, Amazonas, Bahia, Mato Grosso, Pará and Roraima, Brazil, obtaining 52 isolates of D. pulvinata. The antagonistic fungus was isolated on potato-dextrose-agar (PDA) plates and identified based on morphological characteristics of conidiophores and conidia, and colony appearance. The antagonic effect was tested by inoculating D. pulvinata on Fusicladium macrosporum lesions induced on rubber plants, previously. In order to maintain the morphological and pathogenic traits, fungus isolates were preserved by lyophilization, deep freeze (-80oC) and cryogeny. All isolates were introduced into Embrapa Recursos Genéticos e Biotecnologia fungus collection.

O objetivo deste trabalho foi obter isolados com grande potencial antagônico. Em levantamentos realizados em 14 municípios produtores de borracha, localizados nos Estados do Acre, Amazonas, Bahia, Mato Grosso, Pará e Rondônia, obtiveram-se 52 isolados de D. pulvinata. O fungo antagônico, isolado diretamente em meio de cultura de batata-dextrose-ágar (BDA), foi identificado com base na morfologia dos conídios e conidióforos e preservado pelos métodos da liofilização, congelamento à temperatura de -80oC e criopreservação em nitrogênio líquido, a fim de manter as características morfológicas e patogênicas dos isolados. O efeito antagônico foi testado por meio de inoculações de D. pulvinata em lesões de Fusicladium macrosporum induzidas em plantas de seringueira previamente infectadas. Todos os isolados foram incorporados à coleção de fungos da Embrapa Recursos Genéticos e Biotecnologia.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMello, Sueli Corrêa Marques deSantos, Maria de FátimaSilva, João Batista Tavares da2006-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7149Pesquisa Agropecuaria Brasileira; v.41, n.2, fev. 2006; 359-363Pesquisa Agropecuária Brasileira; v.41, n.2, fev. 2006; 359-3631678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7149/4194info:eu-repo/semantics/openAccess2014-09-26T17:38:31Zoai:ojs.seer.sct.embrapa.br:article/7149Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T17:38:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
