Abstract

The use of plant extracts in the management of phytopathogens is a promising alternative to
the use of pesticides. This work aimed to evaluate the effect of aqueous extracts on the mycelial
growth of Sclerotium rolfsii, in vitro. The experimental design was a completely randomized
design with 5 treatments (4 extracts and control without extract) with 6 replicates. To obtain the
aqueous extracts, sterile distilled water was used as the extractor medium, and incorporated
into the BDA culture medium. The evaluations were carried out daily by measuring the mycelial
growth of the pathogen, obtaining the variables mycelial medium growth, mycelial growth rate
index and percentage of growth inhibition. Data were submitted to analysis of variance, followed
by means comparison test. The results obtained indicated a promising effect of extracts
of cinnamon, garlic and pepper on the mycelial growth of S. rolfsii.
