GERALDO, Márcia Regina Ferreira; COSTA, Christiane Luciana da; ARROTEIA, Carla Cristina  and  KEMMELMEIER, Carlos. The neem [Azadirachta indica a: juss (meliaceae)] oil reduction in the in vitro production of zearalenone by Fusarium graminearum. Braz. J. Microbiol. [online]. 2011, vol.42, n.2, pp.707-710. ISSN 1517-8382.

Zearalenone, a mycotoxin produced by fungi of the genus Fusarium, including F. graminearum, triggers reproduction disorders in certain animals and hyperestrogen syndromes in humans. Current research investigates three concentrations of neem oil extract (0.1, 0.25 and 0.5%) in reducing the production of zearalenone. Neem oil extract decreased zearalenone amount in the three concentrations but highest inhibition (59.05%) occurred at 0.1%.

Keywords : Zearalenone; Fusarium graminearum; neem oil extract.
