Abstract:

In this study, fungicidal and fungistatic effects of thyme (Thymus vulgaris L.), cumin (Cuminum cyminum L.), juniper (Ju-niperis communis L.), mint (Mentha piperita L.), picling herb (Echinophora tenuifolia L.), eucalyptus (Eucalyptus sp.) and Medicinal tea (Artemisia sp.) essential oils were investigated against Alternaria mali Roberts, Fusarium oxysporum Synder & Hansen, Botrytis cinerea Pers. Sclerotinia sclerotiorum (Libert) de Bary and Colletotrichum circinans (Berk.) Vogl. in vitro conditions. Essential oils used at1l, 10 l ve 50 l/petri doses. Some of essential oils were exhibited at low degrees fungistatic effect against Fusarium oxysporum, Botrytis cinerea and Colletotrichum circinans while fungicidal effect was’nt observed on fungi at 1 ml/petri doses of essential oils. The other essen-tial oils with exception of picling herb and juniper essential oils completely inhibited mycelial growths of all fungi at 10 and 50l/petri doses, respectively. Furthermore, there were different in point of fungicidal effects among all essential oils. It could be seen that medicinal tea comes the first, when the essential oils put in order according to their fungicidal effects with 10 and 50 µl/plate doses. Thyme, mint, cumin, eucalyptus, juniper and pickling herb oils followed this oil, respectively.
