The search for the preservation of the environment has generated the need to test natural
products, aiming at the alternative control of phytopathogens. In this way, the objective was
to evaluate the potential of aqueous extracts on the in vitro development of Curvularia sp.
The design was completely randomized with 5 treatments and 6 replicates. The concentration
used was of 20% of the aqueous extracts, incorporated into the BDA culture medium. The
evaluations were carried out by means of the daily measurement of mycelial growth (mm) of
the fungus, obtaining the variables mycelial growth medium, rate of mycelial growth rate and
percentage of inhibition of growth. Data were submitted to analysis of variance, followed by
comparison of means. Total inhibition of the mycelial growth of Curvularia sp. treated with clove
and star anise extracts was verified. The pepper extract had a promising effect for the mint
extract, and there was no significant effect.
