Antifungal effects of Micromeria myrtifolia Boiss. & Hohen. in Boiss. and Prangos uechtritzii Boiss. Hawsskn decoctions

Antifungal effect of Micromeria myrtifolia Boiss. & Hohen. in Boiss. and Prangos uechtritzii Boiss. Hawsskn decoctions was tested against Alternaria alternata, Aspergillus niger. Aspergillus parasiticus, Botrytis cinerea. Fusarium oxysporum f.sp. melonis and Penicillium digitatum. Of the 2 substances tested Pr. uechtritzii, being present at 75 to 80% concentration in potato dextrose agar, partly inhibited growth of A. alternata, B. cinerea and P. digitatum. Pr. uechtritzii had higher antifungal effect than M. myrtifolia on mycelial growth during incubation. M. myrtifolia partly affected mycelial growth of A. alternata and A. niger at the beginning of incubation. But the mycelial growth of F. oxysporum was not inhibited by M. myrtifolia concentrations during incubation. Also, Pr. uechtritzii did not have any affect on mycelial growth of A. niger during incubation P. digitatum, the most sensitive microorganism to both decoctions. Higher decoction concentrations of plants used in study will be probably inhibit mycelial growth of microorganisms.
