The reduction in the amount of DON
was ascribed to a lower production, as previous investigations
demonstrated that these three Trichoderma isolates
were not able to degrade DON (Matarese, 2010). It is
important that any potential biocontrol agent for FHB must
have the ability to decrease both fungal growth and DON
production (Palazzini et al., 2007), as previous studies
suggest that an interaction between toxigenic Fusaria and
other fungi can result in a significant accumulation of
mycotoxins (Magan et al., 2003).
