Field experiments were performed during three years (1999, 2000 and 2001) to study fusariosis on oat panicles. The percentage of panicles with fusariosis symptoms ranged from 0.5 to 6 percent. Fusarium panicle blight was caused mainly by Fusarium avenaceum and F. poae. The experiment with panicles artifical infection of 12 genotypes of oat was performed in 2001. The panicles of oat were inoculated with F. poae strain nr 37, which caused a reduction in yield by 37 percent. In the infected kernels the following toxins were detected: nivalenol (from 0.06 to 2.18 mg/kg), deoxynivalenol (from 0.02 to 0.47 mg/kg), T-2 toxin (from 0.02 to 0.71 mg/kg), HT-2 toxin (from 0.03 to 0.59 mg/kg), scirpentriol (from 0.06 to 1.98 mg/kg)
