Abstract

Lichen substances have a wide range of biological activities, including antimicrobial, antitumor, herbicidal and insecticidal action. The objective of this work was to evaluate the biological activity of two lichen species against strains of the phytopathogenic fungi Phytophthora palmivora and Fusarium sp. The zonal inhibition method was used in plates, by sowing mycelium discs of 3 mm in diameter inverted, in the center of Petri dishes with 20 mL of Potato-Dextrose-Agar (PDA) medium. In the culture medium contained in each plate, three 5 mm diameter holes were made, in which the extract of each species was deposited. As a result, extracts from the species Usnea sp. inhibited the growth of both strains, with a significant difference compared to the control, while the extracts of the Cladonia didyma species only inhibited the mycelial growth of Phytophthora palmivo.
