Resumo: | The objective of this work was to evaluate the ability of Trichoderma spp. to promote growth of common bean plants and to reduce severity of anthracnose (Colletotrichum lindemuthianum), as well as to identify the best performing isolates. Sixty Trichoderma spp. isolates were evaluated as to their capacity to promote growth in common bean. The seven isolates that stood out were added to the culture substrate and assessed for reduction in severity of anthracnose in bean plants treated with C. lindemuthianum conidia. The most efficient isolates in controlling the disease were identified by DNA sequencing. The IB 28/07 isolate was evaluated in the concentrations 0.5, 1, 1.5, and 2% (weight:volume), which reduced disease severity in 41.51, 55.15, 81.82, and 96.06%, respectively. The most efficient Trichoderma spp. isolates can promote increases above 30% in dry matter production and reduce disease severity between 63 and 98%. These isolates were identified as belonging to the species Trichoderma harzianum, T. strigosum, and T. theobromicola. |

Sessenta isolados de Trichoderma spp. foram avaliados quanto à capacidade de promoção do crescimento nas plantas. Os sete isolados que mais se destacaram foram adicionados ao substrato de cultivo e avaliados quanto à redução na severidade da antracnose em plantas de feijão tratadas com conídios de C. lindemuthianum. Os mais eficientes no controle da doença foram identificados por sequenciamento de DNA. O isolado IB 28/07 foi avaliado nas concentrações 0,5, 1, 1,5 e 2% (peso:volume), que reduziram a severidade da doença em 41,51, 55,15, 81,82 e 96,06%, respectivamente. Os isolados mais eficientes de Trichoderma spp. podem proporcionar aumentos superiores a 30% na produção de matéria seca da parte aérea das plantas e reduzir a severidade da doença entre 63 e 98%. Esses isolados foram identificados como pertencentes às espécies Trichoderma harzianum, T. strigosum e T. theobromicola.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPedro, Erica Aparecida de SouzaHarakava, RicardoLucon, Cleusa Maria MantovanelloGuzzo, Sylvia Dias2012-12-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/12727Pesquisa Agropecuaria Brasileira; v.47, n.11, nov. 2012; 1589-1595Pesquisa Agropecuária Brasileira; v.47, n.11, nov. 2012; 1589-15951678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/12727/8236https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/12727/8424info:eu-repo/semantics/openAccess2012-12-19T18:13:56Zoai:ojs.seer.sct.embrapa.br:article/12727Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-12-19T18:13:56Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
