A field study was performed to assess whether fungal aerosol of a municipal dump may impact on quantitative and qualitative characteristics of epiphytic mycoflora of crop plants cultivated in vicinity of the dump. Sampling sites were located at every side of the dump. Plant samples were collected from field bean, spring wheat and potato. The highest concentration of fungal aerosol was found at the field located south of the dump within the zone of 250 m next to its borders. For this zone, the most numerous and diverse mycoflora was ascertained, and the plants cultivated were the most damaged. The results suggest that the municipal dump was not the source of phytopathogenic fungi; however, different emissions of contaminants from the dump might cause a decline in the intrinsic plant resistance against the pathogens.
