Resumo: The disease-yield relationship was studied in web-blight (Thanatephorus cucumeris Frank.) of common beans (Phaseolus vulgaris L.) under humid tropic conditions of Transamazon region. Data obtained from 24 different epidemics regulated by the application of fungicidal sprays were utilized. Three methods were tested for relating disease severities to grain yield: 1. critical-point method, 2. multiple-point method, 3. area under disease progress curve. There was no correlation between disease severities at vegetative growth stage and yield. Pod-filling stage was identified as critical for relating disease to grain yield in the cultivar Rico-23. The results further demonstrated that the loss in yield could be determined with reasonable accuracy utilizing the critical-point model.

Utilizaram-se os dados obtidos de 24 diferentes epidemias reguladas com aplicações de fungicidas, em condições de campo. Foram testados três métodos para relacionar severidade de doença com rendimento: 1. método de ponto crítico; 2. método de pontos múltiplos; e 3. área sob curva de progresso de doença. Não houve correlação entre severidade de doença no estádio vegetativo e produção de grãos. A fase de enchimento de vagens foi identificada como ponto crítico para relacionar severidade de doença com produção de grãos da cultivar Rico 23. Os resultados demonstraram que para a determinação de perda em produção de grãos de feijoeiro, causada por murcha da teia micélica, o modelo de ponto crítico é mais adequado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPrabhu, Anne SitaramaPolaro, Raimundo HumbertoCorrea, João Roberto VianaSilva, José Francisco de Assis F. daZimmermann, Francisco José P.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16371Pesquisa Agropecuaria Brasileira; v.17, n.11, nov. 1982; 1607-1613Pesquisa Agropecuária Brasileira; v.17, n.11, nov. 1982; 1607-16131678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16371/10603info:eu-repo/semantics/openAccess2014-04-15T19:48:24Zoai:ojs.seer.sct.embrapa.br:article/16371Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:48:24Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
