Resumo: | At post-harvest period, quality of corn seeds may be influenced by several important factors such as: presence of harmful microorganisms, chemical treatments, host species genotype and storage conditions. The objective of this study was to evaluate the performance of corn seeds, hybrids 2B 688 and 2B 710, with high incidence of fungus Fusarium verticillioides and treated with mixtures of fungicides thiophanate-methyl + pyraclostrobin (50 mL a.i .100 kg-1 of seeds) and carbendazim + thiram + micronutrients (100 mL a.i .100 kg-1 of seeds) during six months storage. Performance assessments of seeds were carried out at 0, 30, 60, 90, 120, and 180 days storage. The incidence of F. verticillioides, as well as physiological quality, germination, vigor, stand of plants, emergence speed index, and dry matter weight were assessed. It has been verified that seed treatment with fungicide mixtures was efficient for ensuring seed physiological quality of both genotypes and to reduce incidence of F. verticillioides on treated seeds. By contrast, analysis between treatments with fungicides, within each period assessed and each treatment as compared to control along storage period was verified clear benefits on emergence of seeds after treatment with fungicides |

By contrast, analysis between treatments with fungicides, within each period assessed and each treatment as compared to control along storage period was verified clear benefits on emergence of seeds after treatment with fungicidesNo período pós-colheita, a qualidade das sementes de milho é influenciada por diversos fatores importantes, entre os quais: presença de microrganismos nocivos, tratamento químico, genótipo da espécie hospedeira e condições de armazenamento. O objetivo deste trabalho foi avaliar o desempenho das sementes dos híbridos de milho 2B 688 e 2B 710, com alta incidência de Fusarium verticillioides, mediante tratamento das sementes com misturas dos fungicidas pyraclostrobin+tiofanato metílico (50 mL i.a. 100 Kg-1 de sementes) e carbendazim+thiram+ micronutrientes (100 mL i.a. 100 Kg-1 de sementes), durante seis meses de armazenamento. As avaliações de desempenho das sementes foram realizadas aos 0, 30, 60, 90, 120 e 180 dias após o início do ensaio. Foram avaliados: incidência de F. verticilliodes; qualidade fisiológica; germinação; vigor; estande; índice de velocidade de emergência; e peso de matéria seca. Verificou-se que o tratamento das sementes, com ambas as misturas, foi eficiente em assegurar a qualidade fisiológica das sementes, de ambos os genótipos e reduzir a incidência de F. verticillioides nas sementes tratadas. Pelas análises de contrastes entre os tratamentos fungicidas, dentro de cada época avaliada e de cada tratamento, em comparação à testemunha, ao longo do período de armazenamento, foram verificados evidentes benefícios às sementes, após o tratamento fungicida.Associação Brasileira de Tecnologia de Sementes2019-12-20T19:13:50Z2019-12-20T19:13:50Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMATOS, C. de S.
