Resumo: The objective of this study was to find effective fungicides against eucalypt powdery mildew. Fungicides tested were chlorothalonil, fenarimol, sulfur, tebuconazole, propiconazole, benzothiazole, pyraclostrobin + epoxiconazole and triadimenol. These fungicides were sprayed on Eucalyptus benthamii seedlings in a greenhouse infested with powdery mildew. Severity was evaluated at 9, 16, 23, 30 and 37 days after spraying, classifying symptoms observed with a scale 0 (symptoms absent) to 4 (strong symptoms). Best treatments were obtained with pyraclostrobin + epoxiconazole, propiconazole + trifloxystrobin and triadimenol, with an infection index average of 0.39, 0.63 and 1.01, respectively.

Foram testados os fungicidas chlorothalonil (2 g/l), fenarimol (0,5 ml/l), enxofre (3 g/l), tebuconazole (1 ml/l), propiconazol 12,5% + trifloxistrobina 12,5% (0,6 ml/l), benzothiadiazol (1g/l), piraclostrobina 13,3% + epoxiconazol 5% (1ml/l) e triadimenol (1 ml/l). Os fungicidas foram pulverizados em 30 mudas por tratamento de Eucalyptus benthamii, naturalmente infectadas. A doença foi avaliada aos 9, 16, 23, 30 e 37 dias após serem colocadas em um ambiente infectado, onde os sintomas foram classificados em uma escala de notas que variam de 0 (ausência de sintomas) a 4 (sintoma muito forte). Os melhores tratamentos foram piraclostrobina + epoxiconazol, propiconazol + trifloxistrobina e triadimenol, apresentando um índice médio de infecção de 0,39 e 0,63 e 1,01, respectivamente.  Embrapa Florestas2011-03-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/234Pesquisa Florestal Brasileira; n. 51 (2005): jul./dez.; 165Pesquisa Florestal Brasileira; No. 51 (2005): jul./dez.; 1651983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/234/185Bizi, Rafaela MazurGrigoletti Júnior, Albino GarciaAuer, Celso Garciainfo:eu-repo/semantics/openAccess2017-04-28T14:11:52Zoai:pfb.cnpf.embrapa.br/pfb:article/234Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T14:11:52Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
