The effect of Nepeta rtanjensis essential oil on test micromycetes mycelia growth

Abstract

The antifungal activity of Nepeta rtanjensis Diklić et Milojević essential oil on mycelia growth has been performed by macrodilution method. The most efficient impact of N. rtanjensis essential oil on mycelia growth in vitro was found in Alternaria species with the same value of minimal inhibitory quantity (MIQ) of 0.6 μl/ml. Bipolaris spicifera and Cladosporium cladosporoioides had MIQ values of 1.0 μl/ml whereas Trichoderma viride with MIQ value of 1.6 μl/ml showed the most efficient defense against the essential oil examined. The values of minimal fungicidal quantity (MFQ) in Alternaria sp. 2, B. spicifera and C. cladosporioides match the MIQ values whereas MFQ values in Alternaria sp. 1 is 0.8 μl/ml, and in T. viride 1.8 μl/ml.
