Thirty-four isolates taken from the head surface of winter wheat varieties were investigated for azoxystrobin and propiconazole plus cyproconazole resistance and degradation ability. The 22 isolated bacteria were able to grow in the presence of both fungicides, but their degradation ability could not be verified. The 3 Aspergillus isolates were resistant to both fungicides, and grew on minimal medium with the azole fungicide as carbon source. From the 4 resistant Fusarium strains, 3 were resistant to azoxystrobin and the azole fungicides, and one, only to the former. Degradation, but also other mechanisms, may have been involved in the development of resistance.
