PGR
Indole-3-Butyric Acid (IBA) 98% TC Powder
IBA, 3-Indolebutyric acid 98% TC grade for formulators; formulate into SL/SP
Indole-3-Butyric Acid (IBA) 98% TC Powder, CAS 133-32-4, is the most effective auxin-type PGR for root formation: it strongly induces adventitious roots, raising both rooting rate and survival of cuttings and transplants. Foliar 5–15 g a.i./ha in vegetative stages; root-zone fertigation 15–30 g a.i./ha; general range 5–30 g a.i./ha. TC grade for formulators; formulate into SL/SP (SP, WDG or liquid solutions). MOQ 25 kg; lead time about 10 working days to Shanghai port; OEM and batch COA available; 24-month shelf life.

Key benefits
- Industry-Standard Rooting Hormone: High-purity Indole-3-Butyric Acid (IBA 98% TC, CAS 133-32-4) serves as the primary active ingredient for commercial rooting powder, liquid rooting concentrate, and tissue culture media formulations.
- Rapid Adventitious Root Induction: Accelerates adventitious root initiation, enhances root tip cell division, and increases total root biomass for softwood and hardwood vegetative cuttings.
- Transplant Shock Reduction & Root Establishment: Promotes robust lateral root branching, ensuring faster soil establishment and significantly improving nursery seedling survival rates.
- High Chemical Stability & Extended Residual Activity: Offers superior chemical stability against light and enzyme breakdown compared to natural indole-3-acetic acid (IAA), providing longer-lasting bioactivity in field applications.
- Synergistic Auxin & Biostimulant Compatibility: Integrates seamlessly with NAA, GA3, humic acids, and amino acids to formulate high-efficiency root dip solutions and biostimulant root boosters.
Suggested dosage & application
For formulators
TC grade; formulate into SL/SP. IBA 98% TC is practically insoluble in water but highly soluble in ethanol, methanol or acetone, and can also be dissolved in alkaline solutions. It is commonly formulated into SP, WDG or liquid solutions. Every shipment includes a batch COA.
For direct field use
Foliar: 5–15 g a.i./ha during vegetative stages. Root-zone fertigation: 15–30 g a.i./ha for root branching and drought resilience. General range: 5–30 g a.i./ha.

Frequently asked questions
01What is the CAS number of indole-3-butyric acid (IBA)?
IBA has CAS number 133-32-4. We supply 98% technical grade (TC) powder with a batch COA for every shipment.
02What does IBA do, and at what rates is it used?
IBA is the most effective auxin-type regulator for root formation: it powerfully induces adventitious roots, raising both rooting rate and survival rate of cuttings. Typical rates: 5–15 g a.i./ha foliar during vegetative stages; 15–30 g a.i./ha root-zone fertigation for root branching and drought resilience; general range 5–30 g a.i./ha.
03Is this a ready-to-use product or a technical-grade material?
It is a TC grade for formulators; formulate into SL/SP. IBA 98% TC is practically insoluble in water but highly soluble in ethanol, methanol or acetone, and can also be dissolved in alkaline solutions. It is commonly formulated into SP, WDG or liquid solutions.
04Any special handling for IBA?
IBA is sensitive to light and high temperatures. Final formulations should be packaged in light-proof, opaque containers and stored cool and dry to prevent premature degradation of the active ingredient.
05What is the MOQ, lead time and shelf life?
MOQ is 25kg. Typical lead time is about 10 working days to Shanghai port; OEM packaging and batch COA are available. Shelf life is 24 months in the original sealed, light-proof packaging.
