“…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].…”

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.

“…After applying Thymus spp. EO, other weed species such as A. retroflexus , Avena fatua L., Datura stramonium L., Lepidium sativum L. and Agrostemma githago L. were also significantly affected, either at germination or at the seedling growth stage [ 6 , 105 ]. These findings indicate that different species of Thymus ( T. fallax Fisch.…”

“…Different studies tested them on a variety of weed species with varying results. Onaran et al [ 105 ] found that M. dumetorum EO suppressed the germination of A. theophrasti better than other tested EOs such as O. vulgare and T. fallax . Another test used the EO from a specific Peppermint cultivar ( Mentha × piperita L. cv.…”

In all farming systems, weeds are the most expensive pest to manage, accounting for 30% of potential losses. In organic farming, the problem may be further amplified by restrictions on herbicides, thus making weeds the main problem faced by organic farmers in the field. In this sense, much research is focusing on the allelopathic potential of plants as an ecological weed control tool. Many plant species can release allelopathic compounds with high phytotoxicity that can be used in weed control. Species belonging to the Lamiaceae family have been studied widely for this purpose, and their essential oils (EOs) appear to be promising bioherbicides. However, there are still many challenges for their development. Considering these aspects, a review of the bioherbicidal effect of EOs from Mediterranean Lamiaceae could help identify the most effective ones and the challenges for their actual development.

“…Therefore, researchers focus on developing new bio-pesticide against weed and controling of plant diseases by using new active molecules such as seconder metabolites (Onaran et al, 2014;Yılar and Kadıoğlu, 2016;Onaran, 2016). Secondary metabolites are naturally contained in plants and their effectiveness on diseases and harmful weeds have been studied by isolating the allelochemicals with the potential of biological activity from the plants.…”

The antifungal and herbicidal activity of Trachystemon orientalis (L.) G. Don aqueous plant extracts were evaluated against important plant pathogenic fungi (Sclerotinia sclerotiorum Lib. De Bary, Alternaria solani (Ellis & G. Martin) Sorauer, Phytophthora infestans (Mont.) de Bary, and Botrytis cinerea Pers.,) and Cuscuta campestris Yunck. Antifungal activity experiments were conducted under laboratory conditions and herbicidal activity was tested in the greenhouses. The leaves, root and flowers of aqueous extracts of T. orientalis at 1, 3, 5, 7, 10 and 20% doses were applied on Potato Dextrose Agar (PDA) and tested to plant diseases, and the dose of 5% of flowers and leaves aqueous extracts of T. orientalis were examined on tobacco (Nicotiana tabacum L.) and sugar beet (Beta vulgaris L.) against C. campestris. Antifungal activity displayed differences inhibited effects on mycelium growth of plant pathogenic fungi according to increasing extract dose and plant pathogenic fungi. The results showed that mycelial growth inhibitions were found effective in all extracts (leaf, flower and root) on S. sclerotiorum 0 to 100%, on A. solani 21 to 100%, on P. infestans 25 to 100% and, on B. cinerea 0 to 100% depending on the extract dose. According to herbicidal activity result the development of C. campestris has been reduced by looking the fresh (in tabocco: 0.3639 g and in sugar beet:0.6749 g) and dry (leaf extracts: in tabacco:0.0675 g and sugar beet: 0.1546 g; flower extracts: in tobacco 0.3246 g and sugar beet: 0.3421g) weight.
