Nutritional constraints on displacement of Fusarium pseudograminearum from cereal straw by antagonists

► Fusarium sp. displacement from straw by different antagonists. ► Antagonistic interactions in dual culture, straw medium with C and N sources. ► C sources utilization pattern suggest competition between three Fusarium spp. ► Dual culture on straw medium indicates sugars does not limit antagonism. ► Urea and nitrate forms more effective in Fp displacement from straw by antagonists.
