River valleys may be such areas. The aim study was identification types fungi, well investigate intensity their occurrence in upper genetic levels meadow muck-glial soils located Liwiec river valley. material for research samples collected October 2018 and May 2019, reaches river. Insecticidal were isolated from individual under using selective substrate isolation method. In course research, insecticidal genus isolated: Beauveria spp., Metarhizium Isaria spp. Lecanicillium with only being found autumn. greatest number infection units formed by fungus its turf level studied.
