Mode of Action:

Gibberellic Acid (GA3) regulates key aspects of plant growth and development by promoting cell elongation and division. It breaks seed dormancy, accelerates germination, enhances flowering, and promotes fruit set and enlargement. GA3 interacts with plant hormones and gene expression pathways to modulate physiological responses essential for crop productivity.

Applications:

• Agricultural Uses:

  • Enhances seed germination and uniform emergence

  • Stimulates stem and internode elongation

  • Promotes flowering and fruit development in fruits like grapes, citrus, and apples

  • Increases grain size and yield in cereals such as rice and wheat

  • Used in sugarcane to improve juice quality and yield

• Horticulture:

  • Improves growth and flowering in ornamental plants

  • Regulates growth cycles in greenhouse crops

• Forestry:

  • Accelerates seedling growth and biomass production

• Formulated Products:

  • Water-soluble powders (WSP)

  • Soluble concentrates (SL)

  • Emulsifiable concentrates (EC)

Toxicological Profile:

• Oral LD₅₀ (rat): >5000 mg/kg (practically non-toxic)

• Skin Irritation: Non-irritant

• Eye Irritation: Mild irritant

• Environmental Impact: Non-toxic to mammals, birds, and beneficial insects; biodegradable in the environment
