Gibberelic Acid 0.186% SP

Gibberellic Acid 0.186% SP is a Plant Growth Regulator (PGR).

SP stands for Soluble Powder, which is a formulation that dissolves readily in water to be applied, typically as a foliar spray.³ The active ingredient is Gibberellic Acid 0.186% SP at a concentration of 0.186% SP (weight/weight).

Gibberellic Acid is a naturally occurring plant hormone (a gibberellin) that plays a crucial role in regulating various physiological processes in plants.

Key Functions and Benefits

When applied to crops, Gibberellic Acid 0.186% SP works by stimulating cell elongation and cell division, leading to several benefits:

• Stem Elongation: It promotes the stretching of stems and internodes, resulting in taller, more robust plants.

• Fruit and Flower Development: It can enhance flowering, improve fruit set, and increase the size and quality of the fruit (e.g., increased cotton boll size, larger grape bunches/berries).

• Seed Germination: It helps break seed dormancy, leading to faster and more uniform germination.

• Delays Senescence: It can delay the aging (senescence) of leaves and tissues, prolonging the plant's productive life.

• Crop Yield: Overall, it is used to improve crop productivity and yield.

Target Crops

This formulation is commonly recommended for use on a wide variety of agricultural and horticultural crops, including:

• Cotton (often specifically for improving fiber quality and boll size)

• Grapes

• Paddy (Rice)

• Sugarcane

• Banana

• Various vegetables and fruit crops

Application and Dosage

• Method: It is typically applied as a foliar spray after being mixed with water.

• Dosage: The specific dosage and application timing vary depending on the target crop and the desired effect. For example, in Cotton, a typical application might be 20-30 grams of the 0.186% SP formulation per acre, diluted in 150-200 liters of water, applied at specific stages like square formation or boll formation.
