Abstract
The results of molecular expertise of phytosanitary state of upper layer of soil from experimental cornfields are presented. Several fungal pathogens from Fusarium, Aspergillus and Penicillium genera were identified using PCR assay. These pathogens were identified in soil samples during the three-year monitoring period and their respective quantities depended on weather conditions. Abiotic factors like air temperature and relative humidity have a significant impact on fungi’s propagation. Weather conditions of the year affected significantly accumulation of F. equiseti, F. graminearum, A. clavatus, P. expansum and P. chrysogenum in soil. A positive correlation between pathogens’ quantities and values of relative air humidity was found.
