The purpose of the investigation was to study the influence of nitrophenol pesticide (DNOC) on nitrogen metabolism measured by growth reduction in the presence of low doses of DNOC. It was established that DNOC (5; 10 mcg/ml) increased the uptake of nitrates from the culture medium which was connected with an increase of the total content of low molecular weight nitrogen compounds and the amine fraction. In the presence of DNOC the quality and quantity of free amino acids was changed On the other hand low concentrations of DNOC decreased the amount of high molecular weight compounds of nitrogen in the mycelium
