Description and Uses

Indole-3-butyric acid is auxin-family plant hormone (phytohormone). IBA is thought to be a precursor of indole-3-acetic acid (IAA) the most abundant and the basic auxin natively occurring and functioning in plants. IAA generates the majority of auxin effects in intact plants, and is the most potent native auxin.
