Essential oils (EA) are some excellent compounds found in the thymus, which can exert antifungal, phytotoxic and insecticidal activities. promotes their exploration and potential agricultural and food uses. The essential oil (EO) obtained from Thymus kotschyanus collected from East AzerbaijanProvince (Iran) was characterized by gas chromatography and mass spectrometry (GCMS) analysis. Thymol is the most important compound (60.48%), although 35 other active compounds were found in EO. A large amount of carvacrol (3.08%), p-cymene (5.56%) and gamma-terpinene (6.67%) were found in EA. The EO of T. kotschyanus has been tested against important plant pathogenic fungi (Botrytis cinerea), Aspergillus niger and Penicillium extension). The antifungal test showed that the use of ≥500 ppm EO produced fungicidal effects on all fungi tested. Similarly, the use of EO ≥ 500 ppm inhibits the germination and subsequent growth of all cultivated weed seeds (Amaranthus retroflexus L. and Panicum miliaceum L.), which proves its herbicidal effect.
