Resumo: The design of strategies to control Leandria momordicae, an inducer fungus of leaf lesions in cucurbits, is difficult due to the limited knowledge on the pathogen survival standard. With the purpose of reducing such defficiency, the fungus was evaluated for its sporulation and establishment capacities in mineral and organic soils contained into 90mm Petri dishes, sterilized and natural, moisturized up to field capacity, under temperature of 18 and 25oC, and 12 hour photoperiod. From January 2000 to June 2002 a survey was performed on fields of cucurbitsinfected and non-infected by the fungus in a 150km land strip and zero to 500m altitude, from South to North and from East to West direction, respectively, starting from Florianopolis, Southern Brazil. The pathogen established in both sterilized soils, regardless of the inoculum sourse and of the temperature without sporulation. In 40% ofthe samples in mineral soil not sterilizede, incubated at 18oC, the fungus estabitished without sporulation when infested by infected leaves.

O desconhecimento do período e da forma de sobrevivência de Leandria momordicae, tanto nas plantas quanto no solo, dificulta o estabelecimento de estratégias de controle da mancha reticulada em cucurbitáceas. Parareduzir esta deficiência, fez-se um levantamento de cucurbitáceas infectadas entre janeiro de 2000 a junho de 2002, numa faixa de 150km compreendida entre os municípios de Florianópolis e Piçarras, SC, e em altitudes de zeroa 500m. Foram avaliadas, sob condições de laboratório, a capacidade do fungo de esporular e de se estabelecer em solos mineral e orgânico, esterilizados ou não, infestados com hifas e com folhas infectadas. Constatou-se que opatógeno pode sobreviver em hospedeiros silvestres ou cultivados na região litorânea de Santa Catarina, desde março a setembro. Nos solos esterilizados, o patógeno estabeleceu-se, sem esporular, independentemente da fontede inóculo e das temperaturas em estudo de 18 e 25C. No solo mineral não esterilizado, incubado a 18 C, o fungo estabeleceu-se, sem esporular, em 40% das amostras, quando infestado por folhas infectadas.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/956Agropecuária Catarinense Journal; Vol. 18 No. 1 (2005); 68-71Agropecuária Catarinense; v. 18 n. 1 (2005); 68-712525-60760103-0779reponame: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/956/854Copyright (c) 2005 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRebelo, José ÂngeloPorto, Miguel Dalmo de Menezes 2021-06-23T14:20:32Zoai:ojs.publicacoes.epagri.sc.gov.br:article/956Revistahttps://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:2021-06-23T14:20:32Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
