The problem of clover sickness in the Republic of Belarus was analysed. Results of breeding of red clover (Trifolium pratense) of Ustojlivy variety with the increased resistance to root rots (Pythium sp., Phoma sp., Phoma trifoli, Fusarium avenaceum, F. gibosum, F. oxysporum var. orthoceras, F. culmorum) were presented. In the seven-species crop rotation with the clover of two-year use new red clover variety Uslojlivy was resistant to the root rots without application of disinfectants. At the first year the desinfectants did not provide yield increases. The presowing treatment of Ustojlivy variety seeds ammonium molibdate showed the highest efficiency indices and which through the intensification of the symbiotic interaction and improvement of nitrogen nutrition made it possible to increase the height of grass stand by 5-10 cm, as well as green material and dry matter content by 15%. Seed presowing treatment did not exercise influence on the field germination rate of the analysed variety by promoted the better viability of plant in the first year of their cultivation. The higher thickness of grass stands caused the increasing of the fodder and seed yielding capacity on the send year of grass stand use. Application of seed encrustation with the fungal preparations in combimnation with molybdenum caused the lowering of the phytopathological loading and increased grass stand density and productivity
