What is indolebutyric acid?

Indolebutyric acid, also known as Indole-3-butyric acid (IBA), is a plant growth hormone commonly used as a rooting agent. It is a member of the indole auxin family and is widely used by promoting the growth of new roots in plants. During plant propagation, IBA can stimulate the rooting of stems or leaves, promote root formation and growth, and contribute to the growth and development of new plants.
