The way one plant affects another by releasing natural chemicals into the soil or air. These chemicals can help or harm nearby plants.

  • Allelopathy can stop weeds from growing.
  • Some trees use allelopathy to reduce competition.
  • Scientists study allelopathy in crop fields.

Adinary Nuance

Allelopathy is more specific than 'competition' or 'chemical effect.' Use it when one plant changes another plant's growth by releasing chemicals. It is not the same as simple shading, crowding, or taking water from the soil. Scientists use it most often in botany and agriculture.
