Resumo: The effects of the fungicides pentachloronitrobenzene, metalaxil/mancozeb and the herbicide trifluralin on the growth of strains of Bradyrhizobium japonicum (29W and SEMIA 587), and Rhizobium leguminosarum bv. phaseoli (C-05 and C-05 II), were studied in agar medium. Strain SEMIA 587 of B. japonicum was more susceptible to these agrochemicals, and strain C-05 II of R. leguminosarum was the most resistant, although it had been susceptible to metalaxil/mancozeb. The respiratory activity, measured by radiorespirometry revealed that the mutant strain of R. leguminosarum, (C-05 II) had its respiratory activity enhanced by all the agrochemicals.

A estirpe SEMIA 587 de B. japonicum foi mais sensível a estes agrotóxicos, e a estirpe C-05 II de R. leguminosarum foi a mais resistente, embora tenha-se apresentado sensível ao metalaxil/mancozeb. A atividade respiratória, avaliada através da técnica de radiorrespirometria, demonstrou que a estirpe mutante de R. leguminosarum (C-05 II) teve sua atividade respiratória estimulada por todos os agrotóxicos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOstiz, Sonia de BarrosMusumeci, Maria RaphaelaTsai, Siu Mui2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15863Pesquisa Agropecuaria Brasileira; v.24, n.6, jun. 1989; 663-667Pesquisa Agropecuária Brasileira; v.24, n.6, jun. 1989; 663-6671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15863/9943info:eu-repo/semantics/openAccess2014-08-26T19:58:03Zoai:ojs.seer.sct.embrapa.br:article/15863Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-26T19:58:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
