A Study on the Phytotoxic Potential of the Seasoning Herb Marjoram (<i>Origanum majorana</i> L.) Leaves
In the search of new alternatives for weed control, spices appear as an option with great potential. They are rich in bioactive natural products and edible, which might minimize toxicity hazard. Marjoram (<i>Origanum majorana</i> L.) is an aromatic herb that has been widely employed as a...
