The occurrence of stem-base diseases in two cultivars of winter wheat were evaluated in a 3-year experiment, using two agrotechnology levels. The two cultivars evaluated were durum wheat of the Komnata cultivar and common wheat of the Ostka Strzelecka cultivar. The highest intensity was noted in the occurrence of two diseases of the complex, i.e. Fusarium foot rot and eyespot. The examined cultivars were characterized by a similar susceptibility to these diseases. There was an observed difference - a slightly higher susceptibility by the Komnata as opposed to the Ostka Strzelecka cultivar - but it was not significant statistically. Significant differentiation in infestation was noted for other experimental factors like cultivation season and the agrotechnology level. Intensification of the occurrence of both stem-base diseases in the experimental seasons did not affect the mean amount and quality of the yield obtained in the experiment.
