As a Plant Hormone

IBA is a plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products.
For use as such, it should be dissolved in about 75% (or purer) alcohol (as IBA does not dissolve in water), until a concentration from between 10,000 ppm to 50,000 ppm is achieved - this solution should then be diluted to the required concentration using distilled water. The solution should be kept in a cool, dark place for best results.
This compound had been thought to be strictly synthetic; however, it was reported that the compounds was isolated from leaves and seeds of maize and other species(Hopkins 1999).
