Resumo: | Leaf anthracnose, caused by Colletotrichum loeosporioides, is the most important disease of seedlings and young peach palm plants (Bactris gasipaes). The objective of this study was to evaluate efficacy of some fungicides for controlling anthracnose on leaves of young peach palm (Bactris gasipaes), in Northwestern Paraná State, Brazil. An assay with randomized block design was carried out, with five different fungicides and a control, with four replicates. The fungicide evaluated were: chlorotalonil (2 g L- ), chlorotalonil+methyl tiophanate (1 + 0,4 g L-1), tebuconazole (0,2 g L-1), azoxystrobin (80 mg L-1) and calda Viçosa (boric acid 3 g L-1; copper sulfate 5 g L-1; zinc sulfate 6 g L-1; hydrated lime 3,5 g L-1). Each fungicide was sprayed five times, at 15 to 20- day intervals. All fungicide treatments reduced the disease intensity; however, the most efficient were chlorothalonil and chlorothalonil+methyl thiophanate. |

All fungicide treatments reduced the disease intensity; however, the most efficient were chlorothalonil and chlorothalonil+methyl thiophanate. A antracnose, causada pelo fungo Colletotrichum gloeosporioides, é uma doença foliar importante da pupunheira (Bactris gasipaes) nas fases de muda e planta jovem. O objetivo do trabalho foi avaliar a eficiência de fungicidas químicos no controle de antracnose em folhas de pupunheiras jovens, no Noroeste do Paraná. O ensaio foi conduzido com o delineamento experimental em blocos ao acaso, com cinco tratamentos com fungicidas e uma testemunha sem fungicida, com quatro repetições. Foram utilizados os fungicidas chlorotalonil (2 g L-1), chlorotalonil+tiofanato metílico (1 + 0,4 g L-1), tebuconazole (0,2 g L-1), azoxistrobina (80 mg L-1) e calda Viçosa (3 g L-1 de ácido bórico; 5 g L- de sulfato de cobre; 6 g L-1 de sulfato de zinco; 3,5 g L-1 de cal hidratada). Cada fungicida foi pulverizado cinco vezes, com intervalo de 15 a 20 dias entre as aplicações. 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 fungicidas mais eficientes no controle da doença foram chlorotalonil e a mistura de tiofanato metílico+chlorotalonil.
