The aim of this study was to compare the incidence of pathogens and pesticide residues in rapeseed samples depending on integrated and organic cultivation systems Vaccum Flask and cultivars.No pesticide residue was detected in seeds coming from the organic production system.However, trace amounts of pesticide residues admissible in rapeseed protection were detected for samples from integrated pest management.Seeds from both cultivation systems were most frequently infested by fungi Alternaria brassicicola Crackers and A.alternata.

The greatest number of Leptosphaeria spp.cultures was obtained from seeds from organic cultivation.
