Head blight (Fusarium graminearum) and deoxynivalenol concentration in winter wheat as affected by pre- crop, soil tillage and nitrogen fertillization.

The influence of different pre –corps and crop husbandry on Fusarium head blight (FHB) incidence in wither wheat test crops was studied in a 2 – year factorial field experiment. Infection by FHB and grain contamination with DON were similar following maize and spring wheat crops, either for silage of for grain, but the method of precrop inoculation by infected grains might have masked differences between pre-crops. The reductions of FHB incidence due to ploughing or nitrolime application were 27 –32% or 31 –59% compared with residues remaining on the surface or calcium ammonium nitrate fertilisation, respectively. Contemporary reductions in DON were less consistent. Results show that crop health can be supported by crop husbandry to some degree, but FHB connot be reliably controlled in suscepitble rotations with abundant sources of inoculum.
