Characteristics of Indole-3-butyric acid potassium salt IBA-K

Indole-3-butyric acid potassium salt (IBA-K) is the potassium salt of Indole-3-butyric acid. It possesses relatively stable properties and is primarily used to promote the development of capillary roots (fine roots) in crops. It is currently recognized as one of the most effective rooting agents available on the market. It can be applied as a basal fertilizer or via fertigation (drenching), and can also be blended with compound fertilizers, mixed fertilizers, BB fertilizers, and other blended fertilizer formulations. When used for the propagation of seedlings via cuttings, it is recommended to use it in combination with Sodium 1-Naphthyl Acetic Acid (Na-NAA)—as Na-NAA primarily promotes the development of the main root system—and for even better results, the addition of Atonik is highly recommended.

IBA-K is a plant growth regulator specifically designed to promote rooting. It induces the formation of adventitious roots in crops. When applied via methods such as foliar spraying or root dipping, it is absorbed through various plant parts—such as leaves and seeds—and translocated throughout the plant body, where it accumulates at the growth points. This accumulation stimulates cell division and induces the formation of adventitious roots, resulting in a root system characterized by high density, straight growth, increased thickness, and an abundance of root hairs. It is readily soluble in water and exhibits higher biological activity than pure IBA. While it undergoes slow decomposition under strong light, its molecular structure remains stable when stored under light-shielded conditions.

1. IBA-K acts upon all actively growing parts of the plant—including roots, tender shoots, and fruits—and exerts a particularly strong effect on cell division and growth promotion within the specific plant parts to which it is applied.

2. IBA-K is characterized by its long-lasting efficacy and its targeted specificity of action.

3. IBA-K promotes the growth of new roots, induces the formation of root primordia, and stimulates the development of adventitious roots in cuttings. It is one of the most widely utilized active ingredients for the propagation and transplanting of ornamental flowers, nursery stock, and other plant materials via cuttings.

4. IBA-K demonstrates superior stability compared to pure IBA; it is completely water-soluble and safe to use, making it an excellent agent for promoting rooting and growth.
