We have found a highly significant correlation between Fusarium graminearum DNA and deoxynivalenol (DON) levels in Finnish oats, barle and spring wheat. Fusarium poae DNA levels were higher in plots with tillage (including ploughing) as compared to those without tillage (direct drilling) in 2005 and 2006 in both oats and barley; the difference was greater a few weeks before harvesting than during it
