Biocidal action of Fique (Furcraea gigantea Vent.) juice on Colletotrichum gloeosporioides isolated from Tamarillo fruit (Solanum betaceum Cav.)
The biocidal action of fique juice on the phytopathogen C. gloeosporioides, which causes anthracnose in tamarillo fruit was evaluated. Concentrations of 1,000, 10,000 and 100,000 µg mL-1 amended in the PDA culture medium were analyzed and tree levels of fermentation which were 0, 4 and 8 days. Mycelial discs of 1.1 cm in diameter were placed in different experimental units and the in vitro growth area was measured after a period of 8 days using the ImageJ software. Only statistically significant differences (P<0.05) occurred between concentrations and between the interaction of two factors. The Maximum inhibition of the pathogen was obtained by using a concentration of 100,000 µg mL-1 and 8 days of fermentation.
