Oregano is a common name for products derived from more than 60 plant species which mostly belong to the families Lamiaceae and Verbenaceae. Within the genus Origanum, fortytwo species and forty-nine taxa (species, subspecies and varieties) divided into 10 groups were classified. The largest number comes from the Mediterranean and it is of local character. [4]. In recent years, interest for use of natural compounds in control of weed species keeps growing. Natural compounds with allelopathic effect generally represent the products of secondary metabolism and are known as allelochemicals. Allelochemicals are safer than synthetic herbicides primarily because they are biodegradable and have a minimal detrimental impact on the environment [7]. During 2016, the allelopathic effect of oregano essential oil was studied on germination of some plant species such as: rucola (Eruca sativa Mill.), onion (Alium cepa L.), kohlrabi (Brassica oleraceavar.gongylodes L.) and kale (Brassica oleracea var. sabauda, L.). Seeds of the mentioned weed species were treated with different concentrations of oregano essential oil in the amount of 200 µl/ml, 400 µl/ml, 600 µl/ml and 800 µl/ml. Distilled water was used as a control. The obtained results indicate that the increase in concentrations of the essential oil results with the reduction in germination of onion and kohlrabi plant seeds, and also with the increase in its inhibitory effects. For kale and rucola seeds a deviation in correlative inhibition of germination at a concentration of 600 µ/ml was established, while the average seed germination was higher than at a lower concentration of 400 µ/ml.
