| Resumo: | Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. is the causal agent of anthracnose, a fungal disease that causes considerable losses in postharvest of tropical fruits production. The aim of this study was to evaluate plant extracts that commonly grow in the State of Puebla, which can inhibit. C. gloeosporioides. and ethanol extracts from the leaves of capulin (Prunus serotina subsp. Capuli), nogal (Juglans regia), pirul (Schinus molle), ruda (Ruta chalepensis) and marubio (Marrubium vulgare) leaves were obtained. Minimum inhibitory concentration (MIC) was determined using different concentrations of the extracts (150 to 2000 mg L-1). Radial growth was evaluated with concentrations below the MIC values; data were fitted to the modified Gompertz model to evaluate maximum growth in the stationary phase, the lag phase and the maximum growth rate. Chloroform extracts of ruda (500 mg L-1), capulin (750 mg L-1) and ethanol extracts of ruda (150 mg L-1) and pirul (300 mg L-1) showed an antifungal effect on C. gloeosporioides, significantly affecting (P< 0.05) maximum growth and radial growth rate of the phytopathogen fungi (60 % of growth inhibition). |
