PGR
Gibberellic Acid
Also known as: GA3, Gibberellin
As a highly effective plant growth regulator (PGR), GA3 (gibberellic acid) offers the key advantage of breaking seed and bud dormancy while significantly promoting cell elongation and division. It not only accelerates the vegetative growth of stems and leaves—enabling dwarf varieties to grow taller—but also improves fruit set, induces the formation of seedless fruit (such as seedless grapes), and hastens crop maturation and flowering.

Key benefits
- Exceptional High-Purity for Premium Formulations With a guaranteed 90% technical grade purity, our GA3 ensures outstanding stability, minimal impurities, and excellent solubility. It provides global formulators with the perfect baseline to create reliable, high-performance liquid or soluble powder end-products.
- Potent Growth Stimulation & Cell Elongation GA3 is a highly effective plant hormone that stimulates rapid cell division and elongation. It accelerates vegetative growth, overcomes dwarfism, and significantly increases the stalk and shoot length of high-value crops.
- Breaks Seed and Bud Dormancy It effectively breaks the dormancy of seeds, tubers, and bulbs, promoting rapid and synchronized germination. This ensures uniform crop establishment and enhanced early-stage vigor for farmers.
- Advanced Flowering and Fruit Regulation GA3 plays a critical role in regulating flowering, improving fruit set, and delaying senescence. It is widely trusted by commercial growers to increase cluster length in grapes, boost the fruit size of cherries and citrus, and optimize harvest timing.
Suggested dosage & application
- For Formulators & Manufacturers As a 90% Technical Grade concentration, this product must be formulated before broad field application. Solubility: GA3 90% TC is easily soluble in organic solvents such as methanol, ethanol, or acetone, and can be formulated into standard commercial products like 4% EC, 10%/20% TB (Tablets), or 20% SP (Soluble Powder). Formulation Note: Maintain a stable pH level (ideally between 3.0 to 5.0) in the final formulation, as gibberellic acid degrades rapidly in alkaline environments.
- Reference Field Application Rates For standard foliar spraying, the general field application dosage ranges from 10 to 50 g of active ingredient per hectare (g a.i./ha), depending on the specific growth stage and target response. To ensure optimal efficiency, the dissolved formulation should be applied uniformly to the crop canopy, ideally during cooler periods of the day to maximize absorption and prevent phytotoxicity.
