Evaluation of the antifungal activity by plant extracts against Colletotrichum gloeosporioides Penz
Aiming to develop more efficient and environmental friendly methods than those available to control Colletotrichum gloeosporioides Penz, which causes blister spot in coffee trees, a search for plants able to produce substances active against such pathogen was carried out. Thus, extracts of 48 plant species, collected at Alto Rio Grande region, in Minas Gerais, were prepared and submitted to in vitro assays with that fungus. The best results were obtained with the extracts prepared from Digitalis lanata Ehrh, Origanum manjorona L., Plantago lanceolata Hook. and Stevia rebaudiana (Bertoni) Bertoni, which inhibited C. gloeosporioides spores germination. After dilution of some active extracts with aqueous 1 % Tween 80 solution in a 1:2 or 1:3 ratio (extract:aqueous solution), their antifungal activity vanished. Some of the active extracts were also submitted to freeze drying and none of them presented any alteration in their antifungal activity. Concluding, several plants presented potential to be used in the search for new bioactive substances to control C. gloeosporioides, especially O. manjorona L., which inhibited 96 % of the fungus spores germination.
