Resumo: The occurrence of bacterial wilt is one of the main restrictions to the tomato production in tropical areas, mainly due to the lack of effective methods of control. The research had the objective to evaluate the efficiency of the essential oil of mustard in the treatment of the soil for the suppression of the population of Ralstonia solanacearum. Initially, different selective mediums were evaluated for the detection and quantification of the bacterial population in the soil. Among the appraised mediums, only two mediums showed appropriate sensibility for the detection of the bacteria, and the South Africa Selective Medium - Elphinstone (SMSA-E) showed the highest recovery tax of the bacteria in the soil, the lowest repression index to the R. solanacearum and highest suppression index of background microorganisms. In the evaluation of the EOM gaseous effect against R. solanacearum, this was capable to inhibit it in vitro development completely. The bacterial colonies that were exposited to the EOM gaseous increased the linkage of cellular metabolites. Anaerobic and gram-positive bacterias were less sensitivity to the product than R. solanacearum. The recovery of the bacteria was not observed with the selective medium SMSA-E, after substratum fumigation for seven days with EOM in concentrations over 100µL of ITCA/L of soil. The tomato plants cultivated in the substratum submitted to this same treatment had not present symptoms of bacterial wilt after 45 days of the transplant.

O presente trabalho teve como objetivo avaliar a eficiência do óleo essencial de mostarda no tratamento do solo para a supressão da população de Ralstonia solanacearum. Inicialmente, avaliaram-se diferentes meios seletivos para a detecção e monitoramento da população da bactéria no solo. Dos meios avaliados, apenas dois apresentaram sensibilidade adequada para a detecção da bactéria, sendo que, o meio South Africa Selective Medium Elphinstone (SMSA-E) possibilitou a maior taxa de recuperação da bactéria no solo, com baixo índice de repressão ao patógeno alvo e alto índice de supressão à microrganismos contaminantes. Quanto ao efeito dos vapores do EOM sobre R. solanacearum, estes foram capazes de inibir completamente o seu desenvolvimento in vitro. A exposição das colônias bacterianas aos vapores do EOM ocasionou aumento do extravasamento de metabólitos celulares. Bactérias anaeróbicas facultativas e/ou gram-positivas foram menos sensíveis ao produto que R. solanacearum. Após fumigação por sete dias do substrato com EOM em concentrações a partir de 100µL de ITCA/L de solo, não se observou a recuperação da bactéria com o meio seletivo SMSA-E. As plantas de tomate cultivadas no substrato submetido a este mesmo tratamento não apresentaram sintomas de murcha bacteriana após 45 dias do transplante.Fundação de Amparo a Pesquisa do Estado de Minas Geraisapplication/pdfporUniversidade Federal de ViçosaMestrado em FitopatologiaUFVBREtiologia; Epidemiologia; ControleTomateMurcha bacterianaÓleo essencial de mostardaRalstonia solanacearumTomatoBacterial wiltEssential oil of mustardRalstonia solanacearumCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::FITOPATOLOGIAÓleo essencial de mostarda e controle experimental da murcha bacteriana do tomateiro (Ralstonia solanacearum): efetividade e toxidez ao patógenoEssential oil of mustard an d bacterial wilt on experimental control in tomato (Ralstonia solanacearum): effectiveness and toxicity to the pathogeninfo: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/pdf275601https://locus.ufv.br//bitstream/123456789/4372/1/texto%20completo.pdf8dc4b9237b3474a70a7b5c112c54fb7dMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain143609https://locus.ufv.br//bitstream/123456789/4372/2/texto%20completo.pdf.txta317fff82e31a095422349f609ca4d62MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3659https://locus.ufv.br//bitstream/123456789/4372/3/texto%20completo.pdf.jpg4a0ea6c406f2158b24d09a0f8d004f29MD53123456789/43722016-04-10 23:09:21.152oai:locus.ufv.br:123456789/4372Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:09:21LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
