Abscisic Acid (ABA) is a fundamental plant hormone, often referred to as the stress hormone, that acts as a primary chemical messenger for survival. It regulates critical stages of a plant’s life cycle—from seed dormancy to environmental adaptation—ensuring the plant can withstand harsh external conditions.
ABA is a staple in agricultural research and commercial farming due to its ability to strengthen crop resilience. Its primary roles include stress management, where it triggers the closure of stomata to prevent water loss during droughts; growth regulation, which ensures plants focus energy on survival during winter or dry seasons; and seed development, where it maintains dormancy to prevent premature germination.
The application of ABA varies depending on the specific needs of the plant. For wheat and rice, it improves tolerance to soil salinity and drought, protecting grain yield. In grapes, it promotes uniform fruit coloring and can accelerate the ripening process. For mangoes, it helps regulate flowering cycles and manages the plant's response to temperature fluctuations.
In modern horticulture and agriculture, ABA is a vital tool for resilience. By enhancing a plant's natural defenses against salinity, extreme temperatures, and dehydration, it helps secure food supplies in increasingly unpredictable climates.
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.

Abscisic Acid is a naturally occurring plant hormone (phytohormone) that plays a crucial role in regulating plant growth, development, and stress responses. It is widely used in plant physiology research, agriculture, and horticulture to study and manage plant adaptation to environmental conditions.
Plant Growth Regulator is a highly effective plant growth regulator containing aminoethoxyvinylglycine (AVG). AVG inhibits the biosynthesis of ethylene in plant tissues, the plant hormone responsible for inducing flowering in pineapples.
Aminoethoxyvinylglycine (AVG) prevents naturally differentiated flowering (NDF), a condition that leads to a disrupted supply of fruit, increased operational costs, and lower returns per acre. Aminoethoxyvinylglycine (AVG) synchronizes harvest, providing growers control over their harvest schedule year-round. Controls naturally differentiated flowering (NDF) in pineapples, synchronizing harvest and allowing pineapple farms to set fruit availability year-round.
