allelopathy-companion-planting
Allelopathy refers to the biochemical phenomenon in which plants release specialized compounds into their surroundings that inhibit or promote the growth, survival, and reproduction of neighboring plants. This process underpins companion planting strategies, where crops are deliberately paired to exploit beneficial allelopathic interactions—such as suppressing weeds or deterring pests—while avoiding harmful ones that stunt growth. Understanding these chemical signaling networks helps researchers design more sustainable, ecologically informed agricultural systems that reduce reliance on synthetic herbicides and pesticides.
