Resumo: Leaf anthracnose, caused by Colletotrichum loeosporioides, is the most important disease of peach palm plants (Bactris gasipaes var. gasipaes) in nurseries in the Central and Southern Brazil. The objective of this study was to evaluate efficacy of some new formulations of fungicides for controlling anthracnose transplants in orchards. An assay with randomized block design was carried out, with five different fungicides and a control, with four replicates. Each replicated had 10 plants. The fungicides evaluated were: piraclostrobin + epoxiconazole (0,13 + 0,05 g.L-1), tetraconazole (0,1 g.L-1), tebuconazole (0,2 g.L-1 ), chlorotalonil (2 g.L-1) e chlorotalonil + Thiophanate-methyl (1 + 0,4 g.L-1). Each fungicide was sprayed seven times, at 15-day intervals. All fungicide treatments reduced significantly the disease severity, providing control up to 68 to 78 %.

Each fungicide was sprayed seven times, at 15-day intervals. All fungicide treatments reduced significantly the disease severity, providing control up to 68 to 78 %. A antracnose, causada pelo fungo Colletotrichum loeosporioides, é a principal doença da parte aérea da pupunheira (Bactris gasipaes var gasipaes) em viveiros de mudas no Centro-Sul do Brasil. O objetivo do trabalho foi avaliar a eficiência de novas formulações de fungicidas no controle de antracnose em mudas de pupunheira, na fase de viveiro. O ensaio foi conduzido no período de abril a agosto de 2006, com o delineamento experimental em blocos ao acaso, com cinco tratamentos com fungicidas e uma testemunha sem fungicida, com quatro repetições. As parcelas foram constituídas por dez mudas. Foram avaliados os seguintes fungicidas através de pulverização da parte aérea: piraclostrobina+epoxiconazole (0,13 + 0,05 g.L-1), tetraconazole (0,1 g.L-1), tebuconazole (0,2 g.L-1), chlorotalonil (2 g.L-1) e chlorotalonil+tiofanato metílico(1 + 0,4 g.L-1). A severidade (percentagem da área foliar doente) a doença foi avaliada quinze dias após a sétima aplicação (última). Verificou-se que todos os tratamentos com fungicidas proporcionaram redução estatisticamente significativa na intensidade da doença em relação à testemunha sem fungicida (P £ 0,05). Os tratamentos com os diferentes fungicidas não diferiram significativamente entre si. Os fungicidas avaliados proporcionaram índice de controle da doença de 68 % a 78 %.  Embrapa Florestas2011-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/220Pesquisa Florestal Brasileira; n. 52 (2006): jan./jun.; 151Pesquisa Florestal Brasileira; No. 52 (2006): jan./jun.; 1511983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/220/171Mafacioli, RudimarTessmann, Dauri JoséSantos, Álvaro Figueredo dosVida, João Batistainfo:eu-repo/semantics/openAccess2021-03-19T21:48:10Zoai:pfb.cnpf.embrapa.br/pfb:article/220Revistahttps://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:2021-03-19T21:48:10Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
