The paper presents results of laboratory studies on the effect of fungicides Topsin M 500 SC, Amistar 250 SC, Bravo 500 SC and Previcur Energy 840 SL on growth and sporulation of entomopathogenic fungi: Metarhizium anisopliae, Beauveria bassiana, Acremonium sp. and Isaria fumosorosea. Previcur Energy 840 SL at different doses strongly inhibited the growth and production of conidia of the tested fungi. The species M. anisopliae was the least sensitive to tested fungicides. In all treatments, while the fungi B. bassiana and I. fumosorosea showed to be the most sensitive.
