In vitro effect of essential oils from aromatic and medicinal plants on mushroom pathogens: Verticillium fungicola var. fungicola, Mycogone perniciosa, and Cladobotryum sp.

Abstract

Lavender, anise, chamomile, fennel, geranium, oregano, parsley, and sage essential oils were tested for their effectiveness against mushroom pathogens: Verticillium fungicola var. fungicola, Mycogone perniciosa, and Cladobotryum sp. Isolates were exposed to the volatile phase of the oils and then ventilated in order to determine if the effect of the oil was lethal to the pathogen. Oregano and geranium oils were the most toxic, having a fungicidal effect at 0.02-0.08 ?l/ml of air, depending on the pathogen. Oregano oil was characterized by high content of carvacrol and thymol, while citranelol and geraniol were the main components of geranium oil.U radu su prikazani rezultati in vitro testiranja efekata etarskih ulja: lavande, anisa, kamilice, moraca, geranijuma, origana, persuna i zalfije, na mikopatogene gljive: Verticillium fungicola var. fungicola, Mycogone perniciosa i Cladobotryum sp. Izolati su izlagani dejstvu para proucavanih ulja, a zatim provetravani, nakon cega je ocenjivan efekat njihovog delovanja. Ulja origana i geranijuma ispoljila su najvecu toksicnost za sve proucavane patogene, sa vrednostima minimalne fungicidne koncentracije izmedju 0.02-0.08 ?l/ml vazduha, zavisno od patogena. Ulje origana imalo je visok sadrzaj karvakola i timola, dok su citraneloli geraniolbile dominantne komponente ulja geranijuma.
