The extracts were obtained from a solution of 80% ethanol combined with the powder of the leaves of the plants and oil extraction by means of Clevenger apparatus. The results for theextracts were submitted to ANOVA and Tukey test at 5%. And from the essential oil were evaluated by percentage inhibition of mycelial growth (PICME). The extracts and essential oils were able to inhibit C. gloeosporioides. The most promising result was obtained with the essential oil ofBaccharis trimerathat it inhibited 100% of the fungus in aliquots from 15μL
