Resumo: Gala-leaf-spot is the most important foliar disease of apple ‘Gala’ occurring in southern Brazilduring summer. It is caused by Colletotrichum spp. Nowadays, the control is done weekly by applying contact fungicides. A predictive system to detect the beginning of the disease based on the occurrence of favorable conditions (rainfall, temperature >15oC and wetness period >10 hours) was tested in order to indicate chemical application. The occurrence of three favorable continuous days was the best indicator as a predictive system to start sprayingwith fungicides in order to control this disease.

A mancha-foliar-da-gala, causada pelo fungo Colletotrichum spp., é a principal doença de verão da macieira ‘Gala’, no Sul do Brasil. Atualmente, o controle é obtido com tratamentos semanais com fungicidas de contato. Um sistema de previsão da condição climática favorável ao início da doença foi testado com a finalidade de definir o momento oportuno para a aplicação de fungicidas. Foi considerado um dia favorável (DF) à doença aquele iniciado por chuva, temperatura>15oC e período de molhamento foliar >10 horas. O sistema de previsão com três dias favoráveis (3DF) consecutivos foi o melhor indicativo para a pulverização com fungicida no controle da doença.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1014Agropecuária Catarinense Journal; Vol. 17 No. 3 (2004); 64-67Agropecuária Catarinense; v. 17 n. 3 (2004); 64-672525-60760103-0779reponame: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/1014/910Copyright (c) 2004 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBecker, Walter FerreiraKatsurayama, Yoshinori Boneti, José Itamar da Silva 2021-07-28T17:17:09Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1014Revistahttps://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:2021-07-28T17:17:09Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
