Abstract: In 2002–2011 the spread dynamics of sugar beet fungal leaf spot diseases were investigated. Was found that the most widespread was Cercospora (Cercospora beticola Sacc.) and Ramularia (Ramularia beticola Fautrey & F. Lamb.) leaf spot diseases. Cercospora leaf spot spread was 46.7 to 100.0 %, the severity – from 1.12 to 56.00 %, Ramularia leaf spot – from 40.0 to 96.7 % and from 1.73 to 20.00 %. Phoma leaf spot (Pleospora betae Björl.) damage on sugar beet crop was less – before harvesting disease spread was 0 % to 84.3 %, and the severity was – 0 to 15.57%. Powdery mildew (Erysiphe betae Vaňha Weltzien) in sugar beet spreaded later than other fungal diseases, but in favourable time for spread of the disease up to 100 % of the plants were infected. Disease severity was also very high – up to 65.10 %. Beet rust has been found in small quantities and only in two years of investigation. Diseases spread and development depended from the weather conditions in July and August
