Fungi are one of the main causative agents of seed rot. Plants produce antimicrobial compounds
that can be used in alternative control of fungi. The objective of this work was to evaluate
the mycelial growth of pathogens of maize seeds in culture medium plus vegetable extracts.
Phytopathogenic fungi (Fusarium oxysporum, Penicillium sp. and Aspergillus sp.) were isolated
from seeds of creole maize var. Jabatão. Extract of orange peel, cumaru bark, black pepper,
chilli pepper and eucalyptus at 2.5% concentration were incorporated into the culture medium
for the evaluation of mycelial growth of fungi. Vegetable extract of chili pepper, chilli pepper,
orange peel and eucalyptus leaves are fungitoxic to F. oxysporum. Vegetable extract of black
pepper, chilli pepper and orange peel are fungitoxic to Penicillium sp. Vegetable extract of chili
pepper and orange peel are fungitoxic to Aspergillus sp.
