Effect of chemical treatments on soil nematode community in winter wheat field

Nematode communities were used as bioindicators of changes in agroecosystems caused by anthropogenic factors. The aim of this study was to examine the impact of chemical disturbances on nematode communities in the soil in winter wheat fields. The sampling was done three times, before disturbances, after fertilization and third time was after insecticides applications. Number of genera significantly decreased after disturbances caused by chemical application, while total number of nematodes did not change significantly in numbers. Maturity index (MI) showed significant differences between first and last sampling, as well as PPI/MI. Plant parasitic index (PPI) did not differ significantly between sampling periods.
