Resumo: Results from ten experiments carried out in laboratory with microbiolization are compared with the chemical control iprodione + thiran as seed treatment against the following pathogens: Bipolaris sorokiniana (inducer of spot blotch, common root rot, and black point), Pyricularia oryzae (incitant of blast), Drechslera tritici-repentis (inducer of tan spot), and Stagonospora nodorum (incitant of glume blotch). In five experiments, seed microbiolization showed efficiency superior (five to nine per cent) to the fungicide treatment when the percentage of fungi on the seeds was evaluated (lots II, IV, V, VII, and VIII). In three experiments, the efficiency was equal (lots I, IX, and X). In two experiments, chemical seed treatment was more efficient (five to six per cent) than microbiologic treatment (lots III and VI). None of the treatments was specific to any pathogen. These results indicated that the biological method is a promising measure to protect seeds against the main wheat pathogens.

Em cinco experimentos, a microbiolização das sementes mostrou uma eficiência superior (cinco a nove por cento), em relação ao tratamento com fungicidas sintéticos, quando foi avaliada a percentagem de fungos nas sementes (lotes II, IV, V, VII e VIII). Em três experimentos, a eficiência foi equivalente (lotes I, IX e X). Em dois experimentos, o tratamento químico foi superior (cinco a seis por cento) ao tratamento microbiológico (lotes III e VI). Não houve especificidade de tratamentos para patógenos. Esses resultados indicaram que o método biológico constitui uma medida de controle promissora contra os principais patógenos da cultura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirada Luz, Wilmar Cório1998-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5081Pesquisa Agropecuaria Brasileira; v.33, n. especial, maio 1998; 509-513Pesquisa Agropecuária Brasileira; v.33, n. especial, maio 1998; 509-5131678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5081/7191info:eu-repo/semantics/openAccess2015-01-20T16:41:21Zoai:ojs.seer.sct.embrapa.br:article/5081Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-01-20T16:41:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
