Nutrient
availability plays a significant role in fungal physiology and
the production of secondary metabolites as mycotoxins
(Filtenborg et al. 1990; Frisvad et al. 1992; Beuchat, 1995).
Results achieved on rice confirmed the ability of T. gamsii
6085 to antagonize F. graminearum and F. culmorum, whose
biomass, in the presence of Trichoderma, was lower than the
control, and DON production was reduced by almost 99%.
