The term was coined by Hans Molisch in 1937 and formalized as an ecological concept by Elroy Rice in his 1974 monograph <em>Allelopathy</em>. Allelopathic compounds — allelochemicals — are released into the environment through root exudation, leaching from leaves by rainfall, volatilization, and decomposition of plant litter.</p> <p>Allelopathy differs from competition. Competition involves two organisms vying for the same resource (light, water, nutrients). Allelopathy involves one organism chemically suppressing another regardless of resource availability. A plant can be allelopathic even when resources are abundant — it is producing toxins, not just consuming resources faster.</p>
