Resumo: | Plants have substances known as secondary metabolites which have diverse functions, among them to protect the plant against attack by pathogens. The use of plants as nematicides for nematode control has been extensively studied and the use of essential oils is an alternative for controlling nematodes in small areas. This study aimed to evaluate the effect of essential oils of wormwood, peppermint, oregano and thyme on the control of Meloidogyne javanica. Initially was assessed in vitro the nematicidal potential of these oils on hatching and mortality of juvenile nematodes. The essential oils were solubilized in dimethyl sulfoxide 2% and applied at the concentrations 0.05%, 0.25% or 0.5% in hatching and juvenile mortality tests. All oils tested reduced hatching and increased mortality of juveniles of M. javanica comparing to the control, for the three concentrations analyzed. Subsequently, the potential of these same oils was tested in a greenhouse in the suppression of the number of root galls and nematode eggs. Two methods were tested: foliar spray on tomato plants and direct addition of essential oils solutions into the soil. The essential oils were solubilized in 2% dimethyl sulfoxide and applied at the concentrations 0.05%, 0.25% or 0.5%, when applied by foliar sprays, and 0.25% and 0.5%, when added to soil. The oils were applied weekly for eight weeks. Sixty days after transplanting, plants were evaluated for shoot mass, root mass, number of galls and number of eggs. None of the oils suppressed the number of galls or eggs when they were applied by foliar sprays or when they were added directly into the soil. |

O emprego de plantas com propriedades nematicidas para o controle de fitonematoides vem sendo muito estudado e o uso de óleos essenciais representa mais uma alternativa no controle de fitonematoides em pequenas áreas. O presente trabalho teve como objetivo avaliar o efeito dos óleos essenciais de losna, hortelã-pimenta, orégano e tomilho no controle de Meloidogyne javanica. Inicialmente avaliou-se o potencial nematicida in vitro destes óleos sobre a eclosão e a mortalidade de juvenis do nematoide. Os óleos essenciais foram solubilizados em dimetil sulfóxido 2% e aplicados nas concentrações 0,05%, 0,25% ou 0,5%, nos testes de eclosão e de mortalidade dos juvenis. Todos os óleos testados reduziram a eclosão e aumentaram a mortalidade dos juvenis de M. javanica em relação à testemunha, nas três concentrações analisadas. Posteriormente, o potencial destes mesmos óleos foi testado em casa de vegetação na supressão do número de galhas radiculares e de ovos do nematoide. Dois métodos foram testados: pulverização foliar de tomateiros e adição direta ao solo das soluções dos óleos essenciais. Os óleos essenciais foram solubilizados em dimetil sulfóxido 2% e aplicados nas concentrações 0,05%, 0,25% ou 0,5%, quando aplicados via pulverização foliar, e 0,25% e 0,5%, quando adicionados ao solo. Os óleos foram aplicados semanalmente por oito semanas. Sessenta dias após o transplantio, as plantas foram avaliadas quanto à massa de parte aérea, massa de raiz, número de galhas e número de ovos. Nenhum dos óleos suprimiu o número de galhas ou de ovos quando foram aplicados via pulverização foliar nem quando foram adicionados diretamente ao solo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em FitopatologiaUFVBREtiologia; Epidemiologia; ControleÓleos essenciaisMeloidogyne javanicaTomateEssential oilsMeloidogyne javanicaTomatoCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::FITOPATOLOGIAPotencial de óleos essenciais no controle de Meloidogyne javanica em tomateiroPotential of essential oils in the control of Meloidogyne javanica in tomatoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf431416https://locus.ufv.br//bitstream/123456789/4409/1/texto%20completo.pdfef204dc49faf9dccd4e32266cf30edf7MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain62859https://locus.ufv.br//bitstream/123456789/4409/2/texto%20completo.pdf.txt3ab1a2788ae9184843e8fadd272f4541MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3560https://locus.ufv.br//bitstream/123456789/4409/3/texto%20completo.pdf.jpg23da0b2ebe9f3e0f08397758fbc9ddd5MD53123456789/44092016-04-10 23:10:02.957oai:locus.ufv.br:123456789/4409Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:10:02LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
