Root Stimulating Hormone Indole Butyric Acid Indole-3-butyric acid IBA 133-32-4 Crystal Powder
IBA is a plant hormone in the auxin family and is an ingredient in many commercial horticultural plant rooting products.
Since IBA is not soluble in water, it is typically dissolved in 75% or purer alcohol for use in plant rooting, making a solution of between 10,000 to 50,000 ppm. This alcohol solution is then diluted with distilled water to the desired concentration. IBA is also available as a salt, which is soluble in 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 compound was isolated from leaves and seeds of maize and other species.

It is a broad-spectrum endogenesis plant growth regulator. It can stimulate rooting system of plant's and
cuttings' (herbaceous and woody ornamentals), and it can increase various fruits and melons' fruit-setting rate. It can promote cell division and cell growth, increase errant roots and fruitage; to prevent plants
from dropping fruit, to change the ratio of male and female flowers;It also can get inside the plant through leaves and cortices to reach the action point with the nutrient flow.
