Indole 3 Butric Acid

Indole Butyric Acid (IBA) is a root-promoting auxin plant growth hormone. Iba hormone induces crops to form adventitious roots, spreads from leaf seeds and other parts into the plant body through leaf spraying, dipping roots, etc., and concentrates on the growth point to promote cell division and induce the formation of adventitious roots, which are characterized by more roots, straight roots, and roots thick, with many root hairs.

Indole-3-Butyric Acid (IBA) has higher activity than Indole acetic acid(IAA). It will slowly decompose under strong light. When stored under shading conditions, its molecular structure is stable.

  1. Indole 3 butyric acidcan act on the vigorous parts of the plant, such as roots, shoots, and fruits. The specific treatment site is strongly manifested as cell division to promote growth.
  2. Have the characteristics of long-term effectiveness and specificity.
  3. Promote the growth of new roots, induce the formation of root bodies, and promote the formation of adventitious roots of cuttings.
  4. Break seed dormancy and promote root development.
  5. IBA hormone is the best rooting hormone at low temperature in winter.



Soak the branches with 20-40mg/L indole butyric acid solution for 3 hours to promote rooting.

Soaking branches at 1000mg/L for 5s can promote rooting.

50mg/L soaking branches for 16 hours can promote rooting.

5-20mg/L soaking branches for 24h can promote rooting.

Sprinkle the soil with 10-80mg/L IBA hormone, which can promote early rooting and developed root system after transplanting.

Dipping or spraying with 250mg/L iba auxin concentration can promote parthenocarpy, increase fruit setting rate, and regulate crop growth.

Dip or spray the fruit with 250mg/L concentration, and spray or spray the fruit with 250mg/L concentration.


  1. Indolebutyric acid is easy to decompose when exposed to light. The product must be packaged in black and stored in a cool and dry place.
  2. The configured aqueous solution must be used immediately.
