Resumo: Leandria momordicae, the causal agent of net spot in cucurbits, is a difficult disease to control dueto the susceptibility of the host, to the poor efficiency of fungicides used in its control, and to the lack of resistant cultivars. Information on host and resistant plant species is essential for the integrated control of this disease. This study had the purpose to determine the reaction of some plant species to L. momordicae. The study was carried out from April to December of 2001, at Epagri/Experiment Station of Itajaí, Santa Catarina, Brazil. Several plant species were cultivated in greenhouse and inoculated with cucumber stems infected by L. momordicae. Both thenon-symptomatic and the symptomatic plants were inoculated again. The former were inoculated with conidia collected from cucumber and the latter with conidia obtained from isolates collected from each species. Cucurbita pepo, Bryonia cretica, Cucumis metuliferus and Sicana odorifera, which are not listed as host plants, were susceptible to L. momordicae, and should be considered as an inoculum source in disease control measures. Melothria pendula, Cucurbita maxima and Cayaponia tayuya did not present disease symptoms induced by thepathogen in both inoculations.

A mancha reticulada das cucurbitáceas, causada por Leandria momordicae Rangel, é uma doença de difícil controle em razão da suscetibilidade do hospedeiro, ineficiência dos fungicidas, falta de cultivares resistentese pelo desconhecimento de fontes de resistência. Neste trabalho, pretendeu-se determinar a patogenicidade de L. momordicae a cucurbitáceas, na busca de espécies não suscetíveis e de novos hospedeiros, para atender a programas de controle integrado deste patógeno. Os ensaios foram conduzidos de abril a dezembro de 2001, na Epagri, em Itajaí, SC. As plantas em cultivo protegido, quando cultivadas diretamente no solo, foram inoculadas pelo método de introdução no ambiente de hastes de pepineiros infectadas pelo patógeno e, quando cultivadas em vasos, pelo método de pulverização de suspensão de conídios. As espécies assintomáticas e as infectadas nãorelacionadas como hospedeiras foram novamente inoculadas em casa de vegetação. As assintomáticas foram inoculadas com suspensão de conídios do fungo isolado de pepineiro, e as sintomáticas, com conídios obtidos daslesões de cada espécie. Cucurbita pepo, Bryonia cretica, Cucumis metuliferus e Sicana odorifera, não citadas como hospedeiros, foram suscetíveis a L. momordicae e devem ser consideradas como fontes primárias de inóculo.Melothria pendula, Cucurbita maxima e Cayaponia tayuya não apresentaram sintomas da doença.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/960Agropecuária Catarinense Journal; Vol. 18 No. 1 (2005); 84-86Agropecuária Catarinense; v. 18 n. 1 (2005); 84-862525-60760103-0779reponame: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/960/858Copyright (c) 2005 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRebelo, José angeloPorto, Miguel Dalmo de Menezes Stuker, Henry 2021-06-23T14:20:32Zoai:ojs.publicacoes.epagri.sc.gov.br:article/960Revistahttps://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
