Resumo: | The antagonistic potential of 190 actinomycetes isolated from rhizosphere, rhizoplane and root tissue (endophytics) of tomato was assessed against Ralstonia solanacearum. Tomato seeds were treated with propagules suspension of these actinomycetes in agitation for ten minutes and then, sowed in R. solanacearum naturally infested soil. The plants were grown at 28oC for 45 days, for wilting control, and the percentage of infected plants was recorded. Eighteen actinomycetes showed 100% of control. The best way of inoculation of the antagonists, such as in seeds, in roots or seeds and root soaking was evaluated. The most efficient way of application (control percentage) was by dipping the seeds in a propagules suspension of actinomycetes. |

Sementes de tomate foram tratadas com suspensão de propágulos destes actinomicetos em agitação por dez minutos, e postas a germinar em solo naturalmente infestado por R. solanacearum em condições controladas por 45 dias, avaliando-se controle da murcha. Dezoito isolados proporcionaram 100% de controle. Foram comparados os métodos de aplicação: por imersão de sementes, imersão de raízes nuas, e imersão de sementes com posterior imersão de raízes. A forma mais eficiente de aplicação, considerando porcentagem de controle, em relação à maioria dos tratamentos, foi a imersão de sementes na suspensão de propágulos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBittencourt Moura, Andréada Silva Romeiro, ReginaldoPrata Neves, Maria Cristina1998-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5029Pesquisa Agropecuaria Brasileira; v.33, n.12, dez. 1998; 2065-2072Pesquisa Agropecuária Brasileira; v.33, n.12, dez. 1998; 2065-20721678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5029/7188info:eu-repo/semantics/openAccess2014-12-17T17:40:21Zoai:ojs.seer.sct.embrapa.br:article/5029Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-17T17:40:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
