It has a deep root system and a metabolism that can generate bioactive compounds with allelopathic effects on other plants in the same environment. The main compound involved in this process is sorgoleone, a benzoquinone derived from root exudates and root hairs, which has herbicidal effects on weeds. Sorgoleone and its associated compounds are continuously released into the rhizosphere during the growing season, influencing the competitiveness of nearby plants and contributing to natural weed control. This allelopathic mechanism is mediated by the enzymatic biosynthesis of sorgoleone and the transport of bioactive compounds in the rhizosphere, offering opportunities for its application in sustainable horticultural systems and integrated weed management. The present study focuses on recognizing the allelopathic properties of sorghum, highlighting its potential as a natural resource for the development of innovative, efficient, and environmentally friendly agricultural practices.EnglishsorghumsorgoleoneallelopathyinfluenceArticle2069-8275
