Resumo: Fusarium Head Blight (FHB) disease, caused mainly by Fusarium gramineraum, is one of the most common in wheat. Besides causing yield reductions, it is also associated with the accumulation of mycotoxins in the kernels, especially deoxynivalenol (DON). This work was carried out in two harvest seasons and aimed at using different sowing dates, cultivars and fungicide applications to help in the increase of yield and kernel quality (decrease of DON contamination). The work was developed under a randomized block design. Weak correlations between FHB incidence, incidence of Fusarium in the kernels and DON were observed. Fungicides helped in the increase of yields and in the achievement of better hectoliter weight and weight of a thousand kernels, mainly in 2019 (more humid year). Fungicides are excellent tools to help achieving higher yields, however, its use must be carried out with caution not to favor mycotoxin biosynthesis and accumulation.

Além de causar reduções na produtividade da cultura, também é responsável pelo acúmulo de micotoxinas, especialmente a desoxinivalenol (DON), em grãos de trigo. Esse trabalho foi desenvolvido durante dois anos agrícolas buscando avaliar a utilização de diferentes cultivares, diferentes datas de plantio e diferentes manejos com fungicidas para aumentar a produtividade e a qualidade dos grãos (menor incidência de DON). O trabalho foi conduzido sob esquema de blocos casualizados. Fracas correlações entre a incidência de giberela, incidência de Fusarium nas sementes e DON foram observadas. O uso de fungicidas ajudou a aumentar a produtividade, o peso hectolitro e o peso de mil sementes do trigo, principalmente em 2019 (ano mais úmido). Os fungicidas são excelentes ferramentas para ajudar produtores a alcançar maiores produtividades, entretanto, seu uso deve ser realizado com cautela para não favorecer a biossíntese e acúmulo de micotoxinas em grãos de trigo.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2022-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/146910.52945/rac.v35i2.1469Agropecuária Catarinense Journal; Vol. 35 No. 2 (2022); 55-61Agropecuária Catarinense; v. 35 n. 2 (2022); 55-612525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIenghttps://publicacoes.epagri.sc.gov.br/rac/article/view/1469/1387Copyright (c) 2022 João Américo Wordell Filho, Rafael Dal Bosco Ducatti, Cristiano Nunes Nesihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessWordell Filho, João Américo Dal Bosco Ducatti, RafaelNunes Nesi, Cristiano2022-09-01T02:31:27Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1469Revistahttps://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:2022-09-01T02:31:27Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
