Many types of organic wastes, including sewage sludge are used for supplementing the soil with the organic matter. The effects of this kind of fertilize are often compared to those of manure. We observed that there was no harmful impact on the winter wheat health if sewage sludge were added to the soil. In the laboratory tests we showed that water extract of sewage sludge as well as humic substances isolated from them were not sources of nutritive substances for tested fungi. Although some changes made in sewage sludge after freezing or autoclaving made them friendly for fungi. Pseudocercosporella isolates were more sensitive for tested substances than Fusarium culmorum. We observed an inhibition of fungal growth but it was mostly due to bacteria.Keywords:
