Preliminary studies on the allelopathic effect of some endemic species of aromatic plants and their possible use as bio-herbicides

Abstract

Allelopathy as a process defines the process of inhibition or influence of some plants on other associated plants, by means of biochemical compounds or by the production of chemical substances that eliminated in nature by various means inhibit the germination of weed seeds. Studies in the scientific literature indicate that the main plants with allelopathic effect are aromatic and medicinal species containing essential acids or essential oils such as basil, rosemary, fennel, mint, lavender, thyme, or mustard. The potential for using these plants to produce natural herbicides can be significant, and the percentage reduction in the amount and germination rate of weed seeds in crops is high. Further study of this phenomenon is necessary for the development of biologically active substances for the treatment of weed infestation of crops. Allelopathy and its beneficial effects help to control weeds without harming the health of people, wildlife and the environment. Our preliminary studies include a review of research to date and a proposal for the use of allelopathic plants in urban and peri-urban gardens.
