Resumo: Stalk rot (SR) and grain rot (GR) occur frequently in crops of maize, causing losses to farmers. The objectve of this study was to evaluate the incidence of SR and GR in six cultvars of maize during the early cycle, conducted in two different sowing dates and to identfy the fungal species associated. The experiment was carried out during the 2007-2008 growing season, in no-tll system and monoculture area, having rye as the preceding winter crop. The experiment was arranged in randomized complete blocks, distributed in a factorial 6 x 2 (six corn cultvars x two sowing dates), with four replicatons. The treatments were: S1 (P30F53/70,000 pl/ha), S2 (AGN 30A09 / 65,000 pl/ha), S3 (CD 308/60,000 pl/ha), S4 (DKB 240/70,000 pl/ ha), S5 (open-pollinated variety SCS154 Fortuna/50,000 pl/ha) and S6 (open-pollinated variety SCS155 Catarina/50,000 pl/ha). The treatments had different behaviors on the incidence of SR and GR. Treatments S1 and S4 had a higher incidence of SR and treatments S1 and S6 had the highest percentage of GR. Fungi Stenocarpella maydis and Fusarium vertcillioides were the mainpathogens to cause SR while Fusarium vertcillioides was predominant in the GR

O objetivo deste trabalho foi avaliar a incidência de PBC e GA em seis cultivares de milho de ciclo precocee verificar as espécies fúngicas associadas. O experimento foi conduzido no ano agrícola 2007-08, em área de monocultura esob semeadura direta com cobertura morta de centeio. O delineamento experimental foi de blocos casualizados, distribuídono esquema fatorial 6 x 2 (seis cultivares de milho x duas épocas de semeadura), com quatro repetições. Os tratamentos foram:S1 (P30F53); S2 (AGN 30A09); S3 (CD 308); S4 (DKB 240); S5 (variedade de polinização aberta SCS154 Fortuna) e S6 (variedadede polinização aberta SCS155 Catarina). Os tratamentos apresentaram comportamento diferenciado quanto à incidência dePBC e GA. Nos tratamentos S1 e S4 ocorreu maior incidência de PBC e em S1 e S6 ocorreu maior percentagem de GA. Osfungos Stenocarpella maydis e Fusarium verticillioides destacaram-se entre os patógenos causadores de PCB, enquanto nosGAs houve predominância de F. verticillioides.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/704Agropecuária Catarinense Journal; Vol. 24 No. 3 (2011); 69-74Agropecuária Catarinense; v. 24 n. 3 (2011); 69-742525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/704/604Copyright (c) 2020 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessWordell, João AméricoCasa, Ricardo TrezziKuhnem Junior, Paulo Roberto2021-02-17T14:36:45Zoai:ojs.publicacoes.epagri.sc.gov.br:article/704Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-02-17T14:36:45Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
