The impact of long term application of pesticides for crops protection on bacteria and fungi resistance has been studied. At first the microbes have been isolated from two soil samples, namely a soil sample contaminated with pesticides, and a control one. Subsequently, under in vitro conditions with the same pesticides present, microbes growth capacities were observed. Growth capabilities of microorganisms isolated from the soils contaminated with Miedzian 50WP, Siarkol 80 extra WP, Triflurotox 250EC have proven to be less impacted (by a few to several %) with these xenobiotics present in the substrates than the capabilities of the microbes from the control soil. The only exception were bacteria from the soil samples treated with Siarkol 80WP whose resistance has been found lower (by app. 10%) than the resistance of microbes from the control soil.
