The research was conduced in the years 1999-2000. The aim of the research was to determine the health condition of overground parts and seeds of the following spring oilseed crops: crambe (Crambe abbysinica Hoechsl.) cv. B o r o w s k i, false flax (Camelina sativa L.) cv. B o r o w s k a, spring rape (Brassica napus ssp. oleifera L.) cv. M a r g o and oleiferous radish (Raphanus •tivus var. oleiferus L.) cv. P e g 1 e t t a. In all the years of the research alternaria, light was found on the leaves and siliques of spring rape and oleiferous radish and on the leaves and stems of crambe. False flax proved to be weakly infected by •pathogens. On its leaves gray mould (Botrytis cinerea) was found in all the years, of the research. The disease was found on the siliques only in 1999. In 2000, powdery mildew was found on spring rape and false flax (respectively, Erysiphe cifearum and E. cichoracearum). The weather conditions affected the intensity the diseases on the studied spring oilseed crops. Alernaria genus, especially A. alternata was most commonly isolated from the of examined p!ants. It constituted from 37% (in crambe) to 63.3% (in spring) of all the isolates. Of the remaining pathogenic species, numerous fungi of Fusarium genus (F. avenaceum, F. culmorum, F. equiseti and F. oxysporum) isolated. They constituted from 1.0% (false flax) to 17.3% (crambe) of the isolates.

The research was conducted in the years 1999-2001. The aim of the research was to determine the health condition of overground parts and seeds of white mustard (Sinapis alba L.) cv. Metex and chinese mustard (Brassica juncea L.) cv. Małopolska. In all the years of the research alternaria blight was found on the leaves of white mustard which injury index ranged from 5.6% in 2001 to 17.6% in 2000. The most dangerous disease of chinese mustard also was alternaria blight and its symptoms were found on leaves and siliques. The strongest infection of leaves was in 2000 (~O%) and the weakest in 2001 (6.7%). In all the years of the research siliques we re rather weak infected (5.0-8.8%). Besides powdery mildew was found on chinese mustard which injury index ranged from 0.3% in 1999 to 32.3% in 2000. Intensity of diseases was affected generaIly by the weather conditions. From the seeds of white mustard and chinese mustard were isolated respectively 263 and 137 colonies. Alternaria alternata was the most numerous species which makes respectively 60.9% and 42.3% isolates. Among the fungi pathogenic for white and chinese mustard were also isolated: A. brassicae, Botrytis cinerea and Rhizoctonia solani.
