When 136 samples of dying carrot seedlings from several fields were analyzed Alternaria rudicina proved to be the most common seedling pathogen (41%), followed by some Fusarium species (27%, mostly F. avenaceum).The less common seedling pathogens were Pythium spp. (13%), Phoma spp.(2,5%) and Botrytis cinerea (1,4%). Some other fungi (Bipolaris sorokiniana, Sclerotinia sclerotiorum, Stemphylium botryosym and Ulocladium consortiale) were found in less than 1% of seedlings examined.
