“…Tagetes minuta essential oil showed the highest inhibition of Amaranthus retrofexus seed germination at 600 µL/L −1 concentrations [21]. Yilar et al [94] reported that Origanum onites essential oil completely inhibited seed germination, and root and shoot growth in Amaranthus retroflexus L. at a concentration of 15 L/Petri. Kordali et al [43] reported that the essential oil obtained from Origanum acutidens and carvacrol and thymol compounds in Rumex crispus 10 µL/Petri application dose, 9.8 µL/Petri carvacrol and 10 µL/Petri thymol petri doses of Rumex crispus completely inhibited seed germination and seedling growth.…”

The use of chemical pesticides to protect agricultural products is a global concern because of their adverse effects on the environment and public health. To avoid the dangers of synthetic herbicides, research has turned to natural alternatives. This study was conducted to evaluate the allelopathic effect of essential oil (EO) extracted from Origanum syriacum, Origanum onites, and Origanum majorana. In addition, the chemical composition of the essential oil was elucidated by gas chromatography and mass spectrometry (GC–MS) analysis. A total of 11 different components of O.syriacum were identified, and the main components were carvacrol (88.49), p-Cymene (5.71), γ-Terpinene (1.63), β-Caryoplhyllene (1.48), and Terpinen-4-ol (0.65), respectively. For O. onites, 10 different compounds were identified, and the main components were carvacrol (58.65), Thymol (30.97), Linalool (4.17), p-Cymene (1.94), and β-Caryoplhyllene (0.98), respectively. Finally, for O. majorana, 14 different compounds were identified, and the main components were carvacrol (40.57), α-Terpineol (29.28), p-Cymene (9.02), γ-Terpinene (5.80), and carvacrol methyl ether (3.46). Finally, 14 compounds from the Origanum majorana species were identified, with carvacrol (40.57), -Terpineol (29.28), p-Cymene (9.02), and -Terpinene (5.80) as the parent compound (3.46). Oxygenated monoterpenes were the highest in all species’ EO content. EOs and plant extracts were tested at 5, 10, and 20 L/Petri concentrations against seed germination and seedling growth in four weed species (Thlaspi arvense, Amaranthus retroflexus, Rumex cripus, and Lactuca serriola). The concentrations of essential oil were set as 5, 10, and 20 µL/Petri dishes for seed germination. In the greenhouse experiment, the final concentration of solutions was set as 20 µL and the solutions were directly sprayed on the surface of the weeds, and the mortality rates were noted after 24 and 48 h of application. It was observed that increasing the application decreased seed germination. The phytotoxic effects on the seedling germination in the greenhouse were observed, resulting in 48.76–94% mortality rates. Consequently, the essential oil from Origanum species could be considered as an alternative bio-herbicide to tested weeds.

Alongside increasing productivity in plant production, reducing crop losses has become a major focus for the struggle of today’s man against hunger. Allelopathy, an ecological phenomenon in which organisms interfere with each other, can be a useful strategy in agricultural systems, especially for weed management. In this study, the allelopathic effects of leaf water extracts from two weed species, Plantago lanceolata and P. major, on the seed germination of some crop plants, including wheat, sunflower, lentil, bean, carrot, radish, and purslane were investigated. In vitro germination assays were conducted to determine the effects of different dilutions of the stock extract on the germination rate. The results of the study showed that as the concentration of the extracts from both weeds increased, germination rates decreased in all crop plants. As to the seeds that were exposed to P. lanceolata extract, the ones with the most inhibited germination were carrot (11.84-100%), purslane (18.53-100%), radish (6.17-98.84%), lentil (13.77-95.56%), sunflower (17.57-94.98%), and wheat (30.12-78.31%). The seeds of beans (28.69-39.15%), on the other hand, were the least affected. Similarly, for seeds exposed to P. major extract, the ones with the most inhibited germination were carrot (4.67-100%), lentil (65.46-99.55%), purslane (25.09-99.24%), radish (48.69-95.51%), sunflower (43.68-93.16%), and beans (20.70-66.80%), while wheat (12.35-60.62%) seeds were the least affected. If purslane and radish are considered as weeds, our findings suggest that higher concentrations of P. lanceolata and P. major extracts can be effective bioherbicides for controlling these weeds.

Traditional methods used to increase plant productivity from the past to the present cause problems owing to their toxicological effects on organism resistance and living things. This has stipulated the creation of strategies to boost plant productivity without adversely affecting the health of living things. Essential oils secreted from various parts of plants stand out as, sustainable, and improvable alternatives and have been the subject of numerous types of research as they have many functional properties. The present research covers the investigation of the allelopathic effect of essential oils of Greek Oregano (Origanum vulgare L. subsp. hirtum), Lavandin (Lavandula x intermedia), and common sage (Salvia officinalis L.) on oilseed plants (Cephalaria syriaca L., Camelina sativa L.) at different ratios. Inhibitory effects of the essential oils obtained by hydrodistillation on the seeds of Cephalaria syriaca L. and Camelina sativa L. species at different concentrations were analyzed under sterile in vitro conditions. The inhibitory effects of essential oils and concentrations were analyzed using the Friedman test. The research revealed that essential oils were effective in weed control through their high inhibitory effect against Cephalaria syriaca L. seeds while reducing the germination power of Camelina sativa L.
