Dang; Pythium spp. were revealed and identified.The symptomatology and forms of disease manifestation were described. Their spread and harmfulness was determined. The most economically important oilseed rape diseases in Belarus were identified as Alternaria blight, Sclerotinia stem rot, Fusarium wilt and gray mould.
