Resumo: | The objective of this work was to evaluate the influence of leaf diseases on the yield of two rice varieties, and to determine the interaction between active ingredients and application stages, for the control of brown leaf spot and oat scald. The products used were: thiofanate methylic, tebuconazole, azoxystrobin and trifloxystrobin + propiconazole, applied in five stages, on the varieties IRGA 417 and El Passo L 144. The parameters observed were disease severity and yield. Chemical control reduced the diseases severity in both cultivars, wich reflected on yield, and was influenced by product e application stage. |

Foram utilizados: tiofanato metílico, tebuconazole, azoxystrobin e trifloxystrobin + propiconazole, aplicados em cinco épocas, às cultivares IRGA 417 e El Passo L 144. Os parâmetros avaliados foram: severidade das doenças e rendimento de grãos. O controle químico proporcionou redução significativa na severidade das doenças, em ambas as cultivares, com reflexo no rendimento de grãos, e foi influenciado pelo produto e pela época de aplicação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCelmer, AlissonMadalosso, Marcelo GripaDebortoli, Mônica PaulaNavarini, LucasBalardin, Ricardo Silveiro2007-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7645Pesquisa Agropecuaria Brasileira; v.42, n.6, jun. 2007; 901-904Pesquisa Agropecuária Brasileira; v.42, n.6, jun. 2007; 901-9041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7645/4564info:eu-repo/semantics/openAccess2014-10-10T20:48:10Zoai:ojs.seer.sct.embrapa.br:article/7645Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-10T20:48:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
