title: Seasonal fluctuation in pathogenicity oFFusarium nivale (Gerlachia nivalis) to Lolium perenns L.
abstract: The changes in the degree of damage caused byFusarium nivale to Lolium perenne plants during different seasons around the year were observed, using the laboratory tests. The periods oF maximal and minimal pathogenicity of the fungus were determined. The graphic picture of seasonal changes in pathogenicity was constructed on the basis of results obtained for Argo variety and breeding population.
