Evaluation of the Antifungal and Herbicidal Effects of Some Lamiaceae Plant Essential Oils in Invitro Conditions

Abstract

This study aimed to determine the herbicidal and antifungal activity of the essential oils of Rosmarinus officinalis L., Salvia absconditiflora Greuter & Burdet and Thymbra spicata L.plants. In this study, plant essential oils against antifungal activity on Pyrenophora graminea plant pathogeni fungi and herbicidal effects on Taraxacum officinale were tested by using 0 (Control), 0.5, 1, 2, 4 μL/petri dish doses. The essential oils were applied by impregnation with a micropipette on filter paper adhered to the covers of petri dishes. As a result, the plant essential oils were found to be phytotoxic on Taraxacum officinale seed germination, seedling growth and Pyrenophora graminea mycelium growth. This plant essential oils are thought to be an alternative to synthetic pesticides in control of diseases and weeds.
