Acts as a plant hormone that regulates growth and development.
Functions as an auxin, promoting root formation and cell elongation.
Serves as a natural plant metabolite involved in physiological processes.
Derived from butyric acid, offering stable chemical properties for agricultural use.
Indole butyric acid (IBA) is a broad-spectrum plant growth regulator from the indole class, known for its strong rooting ability. It promotes rooting and growth in cuttings of both herbaceous and woody ornamental plants. Additionally, it can be used to improve fruit set and increase the rate of fruit formation.
