Abscisic acid (ABA) is a naturally occurring plant hormone that plays a crucial role in the regulation of plant growth and various physiological processes. It is involved in key functions such as leaf senescence (aging), plant dormancy, and seed germination control.

Over the past two decades, the significance of ABA in plant physiology has been extensively studied. Often referred to as a “stress hormone,” abscisic acid plays a vital role in helping plants respond to environmental stresses such as drought, salinity, and temperature variations.

ABA is chemically stable and can dissolve in hot water without degradation, making it suitable for practical applications. One of its most important physiological roles is the regulation of stomatal closure, particularly under conditions where water conservation is critical or when carbon dioxide demand is low. This function helps plants reduce water loss and maintain internal balance during stress conditions.

Additionally, abscisic acid is known to inhibit seed germination, preventing premature growth immediately after seed formation and ensuring proper timing for germination under favorable conditions. Plant growth and development are influenced by a combination of internal signals and external environmental factors, with ABA acting as a key regulator in maintaining this balance.


ABA increases the freezing tolerance and enhances dormancy and for this reason it is increasingly applied to protect against winter injury grape cultivars grown in cold regions.

Abscisic Acid (ABA) is an essential plant growth regulator involved in key physiological processes including seed dormancy, stomatal regulation, and stress signaling. It is extensively utilized in agricultural and research applications to study and manage plant responses to abiotic stress conditions.

Dosage: 10–50 ppm (foliar spray); higher concentrations for stress conditions as recommended. Refer Below for more details.

Enhance plant resilience naturally with Abscisic Acid (ABA) — a powerful plant hormone that supports growth regulation and helps plants adapt to environmental stress conditions, ensuring healthier and more robust crops.

Specific crops (wheat, rice, mango, grapes, etc.) Add tank-mix compatibility and spray schedule

Foliar Spray (Most Common Use)

• General Crops:
  10 – 50 ppm (parts per million)
• Stress Management (drought/salinity):
  25 – 100 ppm
• Horticulture / Fruits:
  20 – 60 ppm

Spray during early morning or evening for best absorption

Soil Application

• Dosage: 50 – 200 ppm solution
• Apply near root zone for stress resistance

Seed Treatment

• Dosage:
  10 – 25 ppm solution
• Soak seeds for 4–12 hours before sowing

Nursery / Tissue Culture

• Dosage:
  0.5 – 5 mg/L
• Used for growth regulation and stress studies

Important Guidelines

• Always dilute in clean water
• Do a small trial before large-scale use
• Do not overdose (may inhibit growth excessively)
• Follow agronomist recommendations for specific crops
