Among winter grain crop diseases, snow mould is one of the most serious diseases, causing considerable yield losses. In 2002–2009, harmfulness of snow mould in winter triticale and efficiency of seed dressing products in controlling the disease were studied. Yielding of winter triticale for different degrees of infection by snow mould was determined. The result of performed studies revealed that yield losses ranged from 7.3 to 42.4% depending on the degree of infection. The calculated relative coefficient of disease harmfulness was 0.77±0.12%, and the harmfulness threshold for snow mould – 27.7±8.0%. Fungicides Maxim SC and Kinto Duo FC showed the best results in controlling snow mould and preventing plant death.
