Resumo: 	Medicinal plants have active compounds in their composition produced from secondary metabolism, which can have fungistatic and /or fungitoxic action on the development of phytopathogens. The objective of this work was to study the effect of aqueous extracts of Ocimum basilicum, Baccharis trimera and Cnicus benedictus on mycelial growth of plant pathogens. The experimental design had three medicinal plants, six concentrations of each aqueous extract (1%, 5%, 10%, 15%, 20%, 25% and 50%), five fungus - Alternaria alternata, Colletotrichum graminicola, Phytophthora sp., Rhizoctonia solani and Sclerotinia rolfsii, and four repetitions for each treatment. The variables analyzed were: inhibition of mycelial growth, mycelial growth and area under the curve of mycelial growth. The aqueous extracts in different concentrations showed significant interactions with the analyzed variables, demonstrating that they have potential to control these pathogens.
