Resumo: | The yield response of upland rice (Oryza sativa L.) to the fungicide sprays was studied in three field experiments. One application of the fungicides tested (benomyl, blasticidin-S, edifenphos, kasugarnycin, benomyl + maneb, kasugamycin + captafol) increased yield as compared to untreated check. Differences were not evident either in neck blast control or in yield response between benomyl and kasugamycin sprays administered separately or in mixtures with maneb and captafol, respectively. Leaf and panicle blast were significantly reduced with one spray applied at heading or at flowering or two sprays in combination with any of these two. Among the fungicides utilized for the control of blast, edifonphos, benomyl, benomyl + maneb significantly reduced disease severity of narrow brown leaf spot. Economic analysis for yield indicated that in the areas with high risk of blast disease, the use of fungicide sprays separately constitutes the most adequate tecnology for disease management. |

Uma pulverização de todos os fungicidas testados (benomil, blasticidin-S, edifenphos, kasugamicina, benomil + maneb, kasugamicina + captafol) aumentou a produção em comparação à testemunha. Não houve diferença significativa no controle da brusone do pescoço da panícula nem na produção de grãos, entre a aplicação de benomile kasugasnicina isolados ou misturados com maneb e captafol, respectivamente. Os índices de brusone nas folhas e nas panículas foram significativamente reduzidos com uma aplicação de fungicida na época da emissão da panícula ou florescimento, ou com duas pulverizações em combinação com qualquer dos dois estádios. Entre os produtos testados para controle de brusone, edifenphos, benomil e benomil + maneb apresentaram resultados superiores na redução de severidade da mancha-estreita. A análise econômica da produtividade alcançada revelou que, no caso de áreas propensas à brusone, a alternativa mais viável é a aplicação de fungicidas simples.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPrabhu, Anne SitaramaFaria, Josias Corrêa deConto, Arnaldo José de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15494Pesquisa Agropecuaria Brasileira; v.18, n.12, dez. 1983; 1333-1340Pesquisa Agropecuária Brasileira; v.18, n.12, dez. 1983; 1333-13401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15494/9442info:eu-repo/semantics/openAccess2014-04-16T18:50:16Zoai:ojs.seer.sct.embrapa.br:article/15494Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:50:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
