W pracy przedstawiono efekt działania różnych stężeń fosforanu mocznika na 6 szczepów grzybów środowiskowych różniących się intensywnością wzrostu, sposobem zarodnikowania i typem tworzonych zarodników (Penicillium italicum, Aspergillus fumigatus, Aspergillus niger, Cladosporium resinae, Mucor hiemalis, Rhizopus nigricans). Fosforan mocznika już w stężeniu 3% w sposób statystycznie istotny ograniczał wzrost masy grzybni wszystkich testowanych grzybów.

In this paper the authors presented the influence of various urea phosphate doses, 1-12%, on the environmental fungi growth depending on its intensity and the type of created spore e.g .(Penicillium italicum, Aspergillus fumigatus, Aspergillus n iger, Cladosporium resinae, Mucor hiemalis i Rhizopus nigricans). The result of urea phosphate effect on fungi was estimated by static culture method using dry mass increase change [g. dry mass/ldm3]. The control was created by the growth of the above mentioned fungi on the basis of urea phosphate free soil. The obtained results were worked out by a statistic method using Duncan 's test. The tested fungi showed different senstivity to the various urea phosphate doses. In the presence of 1% urea phosphate the fungi sensitivity depended on their growth intensity (Aspergillus niger, Mucor hiemalis i Rhizopus nigricans). Additionally, the stimulation of fungi growth with rapid vegetative structure progress was observed. Independently of their physiological properties, significant inhibition of dry mass increase in the range of 3-12% concentration urea phosphate was observed. The result of the use of 3% urea phosphate was the reduction of dry mass growth of all tested fungi.
