Abstract: In a field experiment, the effect of plant protection agents on fungal colonies colonising the rhizoplane and the rhizosphere of Elena winter wheat was determined. Impact super 347 SC (flutriafol and chlorotalonil) limited the number of fungi representing Trichoderma, promoted the growth of both fungi from the Fusarium gene and bacteria of Pseudomonas in addition to tricalcium phosphate hydrolysing bacteria. The plant resistance stimulator Bion 50 WG (acybenzolar-s-methyl) strongly reduced the population of Actinomycetales. Bacteria representing Azotobacter did not respond to the applied agents.
