Resumo: | An increased incidence and severity of Orthotospovirus species has been observed in the peanut crop. The typical symptoms of the virus, usually known as ringspot in peanut and spotted wilt in other crops, include mosaic, chlorotic ring-shaped spots, necrosis, and plant stunting. This study aimed to verify the occurrence of this virus in peanut growing areas in the São Paulo State, Brazil, identify the predominant virus species, and determine losses resulting from the presence of this virus. Surveys were carried out in four peanut commercial areas sown in the municipalities of Santa Adélia and Cândido Rodrigues in the 2014/2015 season using the cultivar Granoleico. The following parameters were evaluated: plant stand, number of plants with symptoms, and severity of these symptoms through a scoring scale of visual symptoms. The results showed that the predominant virus species is Groundnut ringspot tospovirus (GRSV). Also, the lower the stand is, the higher the percentage of plants with virus symptoms. The mean incidence of GRSV in commercial peanut areas is 40%, with mean losses estimated at 38% when GRSV is present and 64% when there is the presence of virus and reduction in plant density. |

Os sintomas típicos da virose genericamente conhecida por “vira-cabeça” em outras culturas e “mancha anelar em amendoim”, incluem mosaico, manchas cloróticas em forma de anéis, necrose e nanismo das plantas. Diante disso, os objetivos deste trabalho foram realizar um levantamento da ocorrência dessa virose em áreas produtoras de amendoim em São Paulo, identificar a espécie viral predominante e determinar as perdas decorrentes da presença desse vírus. Para isto, levantamentos foram realizados em quatro áreas comerciais de amendoim, semeadas nos municípios de Santa Adélia e Cândido Rodrigues, na safra 2014/2015, utilizando a cultivar Granoleico. Determinou-se o estande de plantas, o número de plantas com sintomas e a intensidade destes sintomas através de uma escala de notas de sintomas visuais. Pelos resultados obtidos, constatou-se que a espécie de vírus predominante é Groundnut ringspot tospovirus (GRSV). Conclui-se que quanto menor o estande maior a percentagem de plantas com sintomas da virose. A incidência do GRSV nas áreas comerciais de amendoim é em média de 40% sendo as perdas médias estimadas em 38% quando há a presença do GRSV e em 64%, quando há a presença do vírus e a redução na densidade de plantas.UEL2019-10-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionField Empirical ResearchPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3518610.5433/1679-0359.2019v40n6Supl3p3429Semina: Ciências Agrárias; Vol. 40 No. 6Supl3 (2019); 3429-3442Semina: Ciências Agrárias; v. 40 n. 6Supl3 (2019); 3429-34421679-03591676-546Xreponame:Semina.
