1. 3-Indolebutyric acid ( IBA ) can stimulate rooting of herbaceous and woody ornamentals;
2. 3-Indolebutyric acid ( IBA ) can make some transplanted crops root early and root more;
3. 3-Indolebutyric acid ( IBA ) can promote root elongation growth and root lignification of flowers ( for example: jasmine, begonia, camellia, etc);
4. It can promote fruit set of vegetables and fruits by soaking the branches ( for example: tomato, cucumber, fig, strawberry, raspberry, etc);

3-IndolybutYHic acid



3-Indolebutyric acid ( IBA ) is a broad-spectrum endogenesis plant growth regulator. It can stimulate rooting system, 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.

We also have sodium indolyl butryric acid and potassium indolyl butryric acid, both they can resolve into water easily, and can be absorbed by plant.
