Resumo: | The objective of this work was to evaluate the effects of plant essential oils (EOs) on the growth of Xanthomonas vesicatoria, on bacterial morphology and ultrastructure, and on the severity of tomato bacterial spot. EOs from citronella, clove, cinnamon, lemongrass, eucalyptus, thyme, and tea tree were evaluated in vitro at concentrations of 0.1, 1.0, 10, and 100% in 1.0% powdered milk. The effect of EOs, at 0.1%, on the severity of tomato bacterial spot was evaluated in tomato seedlings under greenhouse conditions. The effects of citronella, lemongrass, clove, and tea tree EOs, at 0.1%, on X. vesicatoria cells were evaluated by transmission electron microscopy. All EOs showed direct toxic effect on the bacteria at a 10%-concentration in vitro. Under greenhouse conditions, the EOs of clove, citronella, tea tree, and lemongrass reduced disease severity. EOs of clove and tea tree, and streptomycin sulfate promoted loss of electron-dense material and alterations in the cytoplasm, whereas EO of tea tree promoted cytoplasm vacuolation, and those of citronella, lemongrass, clove, and tea tree caused damage to the bacterial cell wall. The EOs at a concentration of 0.1% reduce the severity of the disease. |

OEs de citronela, cravo-da-índia, canela, capim-limão, eucalipto, tomilho e árvore-de-chá foram avaliados in vitro nas concentrações de 0,1, 1,0, 10 e 100% em leite em pó a 1,0%. O efeito dos OEs, a 0,1%, na severidade da mancha-bacteriana do tomateiro foram avaliados em plantas de tomateiro em casa de vegetação. Os efeitos dos óleos de citronela, capim-limão, cravo-da-índia e árvore-de-chá, a 0,1%, nas células de X. vesicatoria foram avaliados por meio de microscopia eletrônica de transmissão. Todos os OEs apresentaram efeito tóxico direto sobre as bactérias na concentração de 10% in vitro. Em casa de vegetação, os OEs de cravo-da-índia, citronela, árvore-de-chá e capim-limão reduziram a severidade da doença. Os OEs de cravo-da-índia e árvore-de-chá, e o sulfato de estreptomicina promoveram perda de material eletro-denso e alterações no citoplasma, enquanto o OE de árvore-de-chá promoveu vacuolização do citoplasma, e os de citronela, capim-limão, cravo-da-índia e árvore-de-chá causaram danos à parede celular bacteriana. Os OEs, na concentração de 0,1%, reduzem a severidade da doença.Embrapa Informação Tecnológica Pesquisa Agropecuária Brasileira2018-01-29T11:33:07Z2018-01-29T11:33:07Z2012-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLUCAS, G.
