Product Description
Prohexadione Calcium is a high-performance Plant Growth Regulator widely used in modern agriculture to control vegetative growth, improve crop architecture, and enhance yield quality. It functions as a gibberellin biosynthesis inhibitor, helping regulate internode elongation and reduce excessive shoot growth in fruit trees, cereals, and horticultural crops.
It is widely adopted in integrated crop management programs and often combined with Foliar Fertilizers, Growth Promoters, and Plant Extracts to improve fruit quality, color development, and canopy light penetration. Its relatively short residual activity makes it suitable for sustainable and precision agriculture systems.
Content Note: Prepared by our technical team based on current agronomic literature. Agricultural claims comply with international regulatory guidelines. Last reviewed: April 2026
According to a study in Journal of Plant Growth Regulation (2004), Prohexadione Calcium significantly reduced vegetative shoot growth in apple trees and improved overall fruit quality parameters.
A study published in HortScience (2006) reported improved light distribution within the canopy and enhanced fruit coloration following Prohexadione Calcium application in orchard systems.

Prohexadione Calcium is widely used in modern orchard management systems where controlled vegetative growth is essential for improving fruit quality and production efficiency.
Buyer Insight: Prohexadione Calcium is increasingly preferred over long-residual retardants due to its safer profile, faster degradation, and compatibility with integrated nutrient systems.
It is used as a Plant Growth Regulator to control vegetative growth and improve crop quality in orchards and field crops.
It is commonly used in apples, pears, cereals, peanuts, and various horticultural crops.
It is applied as a foliar spray during early vegetative or post-flowering stages depending on crop type.
Yes, when used at recommended rates, it provides effective growth control with high crop safety.
Yes, we provide full OEM services including formulation, packaging, and regulatory documentation support.
