摘要

Cercospora beticola Sacc. is the most destructive foliar pathogen of sugar beet (Beta vulgaris L.) in many beet growing regions of the world. This paper summarizes the most important knowledge about the prevention of fungal infections, as well as themechanisms of sugar beet resistance to infection. The methods of chemical protection of sugar beet against C. beticola and the action of active substances on the physiological processes of the fungus have been described as well. The factors stimulating resistance of C. beticola to fungicides and methods of preventing this phenomenon were indicated. The presented discussion was based on Polish and worldwide literature.
