Summary: The Alternaria spot is one of the main canola’s diseases and it’s reported in all regions that producing this oleaginous, being transmitted by several ways. The aim of this study was to investigate whether sowing spacing in canola combined with the fungicides applications has an effect on the damage caused by Alternaria leaf spot and how these are reflected on crop yield. The studied hybrid was ‘Nuola 300’, and the experimental design used was randomized blocks with a subdivided plot scheme, with four replications. In the main plots, the row spacing (17 cm and 50 cm) was arranged, and in the subplots, the fungicides applications (T1 - control, without fungicide; T2 - azoxystrobin + tebuconazole, in stage B4; T3 - azoxystrobin + tebuconazole, in B4 and pyraclostrobin + fluxapyroxad, in B4 + 15 days; T4 - pyraclostrobin + fluxapyroxade, in stage B4 + 15 days). Under conditions in which the experiment was conducted, in the region of Erechim - Rio Grande do Sul, Brazil, there were control of Alternaria spot in canola leaves and siliques with the application of the fungicides azoxystrobin + tebuconazole and pyraclostrobin + fluxapyroxade, and the best control in siliques was obtained at 17 cm row spacing. The treatment with pyraclostrobin + fluxapyroxade in the 50 cm row spacing showed the highest number of siliques by plants and the highest productivity.

Objetivou-se investigar se o espaçamento de semeadura em canola combinado com a aplicação de fungicidas produz efeito sobre os danos causados pela mancha de Alternária e como estes se refletem sobre o rendimento da cultura. O híbrido estudado foi o ‘Nuola 300’ e o delineamento experimental utilizado foi o de blocos ao acaso, em esquema de parcelas subdivididas, com quatro repetições. Nas parcelas principais foram dispostos os espaçamentos entre linhas (17 cm e 50 cm) e, nas subparcelas as aplicações de fungicidas (T1 - testemunha sem fungicida; T2 - azoxistrobina + tebuconazol, no estádio B4; T3 - azoxistrobina + tebuconazol, em B4 e piraclostrobina + fluxapiroxade, em B4 + 15 dias; T4 - piraclostrobina + fluxapiroxade, no estádio B4 + 15 dias). Nas condições de condução desse experimento, na região de Erechim – RS, houve controle da mancha de alternária em folhas e síliquas de canola com a aplicação dos fungicidas azoxistrobina + tebuconazol e piraclostrobina + fluxapiroxade, sendo que o melhor controle em síliquas foi obtido no espaçamento de 17 cm entre linhas. O tratamento com piraclostrobina + fluxapiroxade no espaçamento de 50 cm entre linhas apresentou maior número de síliquas por plantas, bem como maior produtividade.Universidade do Estado de Santa Catarina2023-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/2251310.5965/223811712212023044Revista de Ciências Agroveterinárias; Vol. 22 No. 1 (2023); 44-51Revista de Ciências Agroveterinárias; v. 22 n. 1 (2023); 44-512238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/22513/15326https://periodicos.udesc.br/index.php/agroveterinaria/article/view/22513/15924Copyright (c) 2022 Authors & Revista de Ciências Agroveterináriasinfo:eu-repo/semantics/openAccessTonin, Rodrigo JoséMezomo, Márcio PauloBrandler, DaianiCeluppi, GabrielFavaretto, Lucas AndreiGallina, AlessandraBragagnolo, JardesMilanesi, Paola Mendes2024-02-29T12:13:52Zoai::article/22513Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2024-02-29T12:13:52Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
