Osetljivost patogena šampinjona Verticillium fungicola var. fungicola, Mycogone perniciosa i Cladob otry um sp. na neka etarska ulja

Antifungal activity of 18 essential oils was evaluated against Verticillium fungicola var. fungicola, Mycogone perniciosa and Cladobotryum sp., the causal agents of button mushroom diseases. Essential oils including: turpentine, basil, lemon, mint, fenchel, rose geranium, anise, cinnamon, scots pine, clove, thyme, juniper, lavender, orange, eucalyptus, rosemary, bergamot orange and tea tree, were screened for their effectiveness against the pathogens in vitro. In order to investigate fungicidal activity, isolates were exposed to the volatile phase of the oils for seven days. Of the 18 essential oils analyzed, cinnamon, clove, thyme, and tea tree showed the highest antifungal activity against all investigated mycopathogens, with Minimum Fungicidal Concentration (MFC) being 0.02 μl/ml of air. Turpentine essential oil expressed the lowest antifungal effect to all isolates tested.U radu je ispitivano delovanje 18 etarskih ulja na Verticillium fungicola var. fungicola, Mycogone perniciosa i Cladobotryum sp., prouzrokovače bolesti šampinjona. Ispitano je antifungalno dejstvo etarskih ulja: terpentina, bosiljka, limuna, pitome nane, mora.a, geraniola, anisa, cimeta, bora, karanfili.a, timijana, kleke, lavande, pomorand.e, eukaliptusa, ruzmarina, bergamota i čajnog drveta na porast izolata in vitro. Fungicidni efekat gasovite faze etarskih ulja na izolate je određen nakon ekspozicije od sedam dana. Među 18 proučenih etarskih ulja, cimet, karanfili., timijan i čajno drvo su najtoksičniji za sve izolate mikopatogenih gljiva sa minimalnom fungicidnom koncentracijom od 0.02 μl/ml vazduha. Najslabije inhibitorno dejstvo ispoljila su ulja terpentina na sve testirane izolate
