“…Two scientific works have published the results of phytotoxic activity of O. vulgare ssp. hirtum L. where the dominant compounds were identified in the first case as o-cymene 19.8%, thymol 27%, and carvacrol 19% [8], and in a second study as 1,8 cineol 36% and camphor 17% [36]. Compared to other studies which focused on the same species as our experiment (O. vulgare), the dominant compounds were identified as (1) (carvacrol 44% and p-cymene 42%) [38]; (2) carvacrol (34.0%), γ-terpinene (21.6%), and p-cymene (9.4%) [29], and unspecified species of Origanum (3) carvacrol (60%), p-cymene (15.5), and γterpinene (5%) [39].…”

“…All studies focused of testing the phytotoxic activities on dicot model plant species and the results showed strong activity in each of these studies, although different EO doses were used. The herbicidal effect was evaluated on seed germination as well as on root length respective to seedling development [5,8,27,28,36,38].…”

“…Essential oils (EOs) are complex mixtures of mostly terpenoids as plant secondary metabolites. It has been recognized that various EO components act as multi-target molecules exerting several MOAs in the recipient-organism [7,8], that can be beneficial compared to conventional herbicides which induce resistance [9]. Single EO molecules are able to cross the cell wall and directly interact with the plant plasma membrane, which is one of the potential cellular targets of EOs.…”

Searching for new bio-based herbicides is crucial for decreasing chemical pollution, protecting the environment, and sustaining biodiversity. Origanum vulgare is considered a promising source of essential oil with herbicidal effect. The mode of action is not known. The present study focused on (1) comparison of phytotoxic activity of Origanum vulgare EO on monocot (Triticum aestivum and Hordeum vulgare) and dicot species (Lepidium sativum and Sinapis alba); (2) and evaluating other antimicrobial biological activities against phytopatogen bacteria (Clavibacter michiganensis, Pseudomonas syringae pv. phaseolicola, Pseudomonas savastanoi, and Xanthomonas campestris); antifungal activity against Monilinia fructicola, Aspergillus niger, Penicillium expansum, and Botrytis cinerea; cytotoxic activity and antioxidant activity. According to the GC/MS analyses, the EO belongs to the thymol chemotype O. vulgare with its high content of thymol (76%). Germination of all four species was not influenced by EO. The phytotoxic effect was statistically significant in the monocot species, while in the dicot species the opposite was observed—a stimulation effect, which was also statistically significant. Strong biological activity of O. vulgare EO was noted on all phytopatogen bacteria and fungi in the highest dose. Cytotoxic activity showed an IC50 = 50.5 μg/mL. Antioxidant activity showed an IC50 = 106.6 μg/mL after 45 min experimental time. Based on the presented results, it is possible to conclude that thymol chemotype O. vulgare essential oil could be potentially used as a herbicide with selective effects on monocot plant species.

“…Phytotoxic potential of O. vulgare ssp. hirtum EO has been evaluated on plant model Arabidopsis thaliana through a physiological and metabolomic approach by Araniti and coworkers, [204] with the evidence that EOs firstly caused growth reduction and leaf chlorosis, together with a series of interconnected metabolic alterations. Interesting is the work of Atak et al [205] on the herbicidal effect of O. onites and R. officinalis EOs on germination and seedling growth of bread wheat and weeds (Avena sterilis and Sinapis arvensis).…”

Lamiaceae is one of the largest families of flowering plants comprising about 250 genera and over 7,000 species. Most of the plants of this family are aromatic and therefore important source of essential oils. Lamiaceae are widely used as culinary herbs and reported as medicinal plants in several folk traditions. In the Mediterranean area oregano, sage, rosemary, thyme and lavender stand out for geographical diffusion and variety of uses. The aim of this review is to provide recent data dealing with the phytochemical and pharmacological studies, and the more recent applications of the essential oils and the non‐volatile phytocomplexes. This literature survey suggests how the deeper understanding of biomolecular processes in the health and food sectors as per as pest control bioremediation of cultural heritage, or interaction with human microbiome, fields, leads to the rediscovery and new potential applications of well‐known plants.

“…In addition, since EOs usually have various modes of action, it is more complicated for weeds to easily develop resistance against them [ 16 , 17 ]. In fact, EOs can suppress the weed growth by affecting biochemical and physiological processes such as reducing cell survival, chlorophyll and RNA contents; acid soluble carbohydrates; and water-soluble carbohydrates [ 18 , 19 ]. Despite their allelopathic potential, many EOs are classified as “Generally Recognized as Safe” (GRAS) by the US Food and Drug Administration [ 20 ].…”

Essential oils (EOs), extracted from aromatic plants, have been proposed as candidates to develop natural herbicides. This study aimed to evaluate the herbicidal potential of Thymbra capitata (L.) Cav., Mentha × piperita L. and Santolina chamaecyparissus L. essential oils (EOs) on Avena fatua L., Echinochloa crus-galli (L.) P. Beauv, Portulaca oleracea L. and Amaranthus retroflexus L. and their effects on soil microorganisms. A pot experiment was set up and three EOs at three doses were applied by irrigation. Efficacy and effects of EOs on weed growth were determined. Soil microbial biomass carbon and nitrogen, microbial respiration, and the main microbial groups were determined at days 7, 28 and 56. EOs demonstrated herbicidal activity, increasing their toxicity with the dose. T. capitata was the most effective against all weeds at the maximum dose. P. oleracea was the most resistant weed. Soil microorganisms, after a transient upheaval period induced by the addition of EOs, recovered their initial function and biomass. T. capitata EO at the highest dose did not allow soil microorganisms to recover their initial functionality. EOs exhibited great potential as natural herbicides but the optimum dose of application must be identified to control weeds and not negatively affect soil microorganisms.
