Resumo: The Asian Soybean Rust (Phakopsora pachyrhizi Sidow), was recently found in Brazil. The disease has caused serious yield reduction. The lack of knowledge about many aspects of this disease, experiments were run out in order to get control strategies. The initial research goal included the lab and greenhouse work with Phakopsora pachyrhizi, under controlled conditions. In addition, it was evaluated the reaction of soybean cultivars to Phakopsora pachyrhizi, the efficacy of chemical control under preventative and curative applications of Pyraclostrobina and Epoxiconazol, and the effect of canopy coverage, gallonage (L/ha) and the utilization of adjuvants on fungicides efficacy. It was observed partial resistance of soybean cultivars. Also, an increase of susceptibility as reproductive phase get closed was evaluated. Preventative and curative effect was determined at 42 and 36 days, respectively. The number of droplets and gallonage influenced de efficiency of Pyraclostrobina + Epoxiconazol. The addition of adjuvant did not result on fungicide efficiency increase

O presente trabalho teve como objetivo inicial o estudo de Phakopsora pachyrhizi, agente causal da ferrugem asiática em ambiente parcialmente controlado. Adicionalmente foram conduzidos experimentos para avaliar a reação de 15 cultivares de soja à ferrugem asiática, determinar a eficiência de programas de controle preventivo e curativo incluindo os fungicidas Pyraclostrobina e Epoxiconazol, utilizados em mistura ou em separado, e a influência do número de gotas por cm2 de área foliar, volume de calda e utilização de adjuvantes na eficiência de Pyraclostrobina + Epoxiconazol no controle de ferrugem em soja. Os resultados obtidos demonstraram a existência de cultivares com mecanismos variados de resistência parcial, demonstrando aumento de suscetibilidade com a aproximação da fase reprodutiva. Foi observado efeito protetor em aplicações preventivas e curativas da mistura Pyraclostrobina + Epoxiconazol na ordem de 42 e 36 dias, respectivamente. Em adição, o número de gotas e o volume de calda, influenciaram significativamente a eficácia da mistura Pyraclostrobina + Epoxiconazol, sendo que a adição de adjuvantes não resultou em aumento de eficácia aos fungicidasapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaFerrugem asiáticaDecréscimos da produtividadeSojaFungicidasCNPQ::CIENCIAS AGRARIAS::AGRONOMIAControle de ferrugem asiática (Phakopsora pachyrhizi Sidow) na cultura da sojaControl of asian rust (Phakopsora pachyrhizi Sidow) in the culture of the soybeaninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBalardin, Ricardo Silveirohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721447T7Silva, Antonio Carlos Ferreira dahttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4784898Z7Medeiros, Luis Aquiles Martinshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4791090J8Ugalde, Mauro Giuliani500100000009400500300500300db30a6fa-b8fd-467f-8b97-06372e631430ed1f74e3-a8d0-426d-b20d-1f40c9900d6fa9badb65-5fab-4e20-b834-002be3e8ad36238d79a7-7544-498a-be31-679bd382e7cfinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMauro.pdfapplication/pdf1228103http://repositorio.ufsm.br/bitstream/1/5127/1/Mauro.pdf3583ac2c83553b074e79a7dcf1c2543fMD51TEXTMauro.pdf.txtMauro.pdf.txtExtracted texttext/plain126419http://repositorio.ufsm.br/bitstream/1/5127/2/Mauro.pdf.txte25a55c011334fde2310a893967b099bMD52THUMBNAILMauro.pdf.jpgMauro.pdf.jpgIM Thumbnailimage/jpeg4904http://repositorio.ufsm.br/bitstream/1/5127/3/Mauro.pdf.jpg924c56cfbdf95d9fcef857693b40ebd6MD531/51272021-02-01 08:15:16.875oai:repositorio.ufsm.br:1/5127Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2021-02-01T11:15:16Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false
