Antifungal (in vitro) activity of plant extracts for the control of anthracnose (Colletotrichum acutatum)

The antifungal effect of five plant extracts: nettle (Urtica dioica), chamomile (Chamaemelum nobile), frame (Artemisia vulgaris), lavender (Lavandula officinalis) and chamico (Datura ferox) were evaluated at laboratory level for control of anthracnose (Colletotrichum acutatum) of the tree tomato (Solanum betaceum), using two methods of extraction (maceration and steam trapping), in the results obtained, statistical differences were observed in the percentage of inhibition of mycelial growth of the fungus, the treatment with lavender extract obtained by the steam trapping method presented the greatest efficiency for anthracnose control (66.23%). The other treatments tested also showed effectiveness against the anthracnose pathogen in the following order of inhibition: chamomile (52.78%), frame (21.63), chamico (24.14%), nettle (12.94), the ability of various species to inhibit certain fungal diseases, taking into account the different content of secondary metabolites that have each of the plant species, constituting new clean production alternatives that reduce the use of chemical pesticides for the control of fungal diseases.
