It is determined that application of microfertilizers did not have significant influence upon course of a disease. Affection of cultivars of winter rape depended mainly on periods of sowing and properties of a cultivar. Conclusions. Cultivars of winter rape Vesuviy and Snizhna Koroleva were rather stable against false mildew in an early period of sowing. Comparative resistance against phomosis and alternaria was manifested by these cultivars in optimum and late periods of sowing. In an early period of sowing microfertilizer Vuksal microplant was highly effective against sicknesses, while in optimum and late period of sowing – Terios and Askofol.
