Abstract

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 %.
