Allelochemicals and their importance [PDF]

open access: yes
Allelochemicals are secondary plant metabolites capable of influencing the growth, development, and metabolism of other plants, microorganisms, or insects in their immediate environment. These substances are a key mechanism in the phenomenon of allelopathy, which refers to chemical interactions between organisms that can be either positive or negative.
