Product Description
Prohexadione Calcium is a highly effective Plant Growth Regulator widely used in modern agriculture to control vegetative growth, improve crop structure, and enhance yield quality. As a gibberellin biosynthesis inhibitor, it regulates plant height and internode elongation, making it an essential tool for fruit orchards, cereals, and horticultural crops.
In the global agrochemical sector, Prohexadione Calcium is increasingly adopted in Agricultural Enzymes-integrated crop systems and precision farming programs. It supports sustainable agriculture practices by reducing excessive vegetative growth, minimizing lodging, and improving fruit coloration and firmness. It is often formulated alongside Foliar Fertilizers and Growth Promoters for optimized crop performance.

According to a study in Plant Growth Regulation (2004), Prohexadione Calcium significantly reduced shoot growth in apple trees while improving fruit set and quality.
A study published in HortScience (2006) reported that Prohexadione Calcium application improved canopy light penetration and enhanced red coloration in apple cultivars.

Prohexadione Calcium is often integrated into crop management programs with Rooting Agents and Growth Promoters, contributing to balanced plant development and improved productivity.
Buyer Insight: Prohexadione Calcium is preferred in orchard management due to its fast action, low residue profile, and compatibility with integrated pest and nutrient management systems.
It acts as a Plant Growth Regulator that inhibits gibberellin biosynthesis, controlling excessive vegetative growth and improving crop quality.
It is widely used in apple, pear, cereals, peanuts, and various horticultural crops.
It is commonly applied as a foliar spray during early growth stages or post-bloom depending on crop type.
It has a relatively low residue profile compared to other regulators, making it suitable for sustainable agriculture programs.
