The antifungal activity from rice, oat and wheat crude proteic extracts on the development of Fusarium graminearum CQ244, Aspergillus flavus CCT 1217 and Rhizopus oryzae CCT 7560 was investigated intending to identify their potential as natural fungicides. The crude proteic extracts from cereals were prepared in ethanol and the antifungal properties were evaluated using the glucosamine, produced by the biomass as a response. F. graminearum was inhibited by wheat extracts, while that A. flavus was inhibited by oat extracts. R. oryzae was few inhibited. Proteic extracts in higher concentrations may be applied in field and/or storage, as natural antifungal.
