Prohexadione Calcium 10% SC

Pesticide registration number: PD20240886

Product Features:
Prohexadione calcium mimics the structure of 2-oxoglutarate, competitively inhibiting the activity of hydroxylases, thereby inhibiting the synthesis of active gibberellins. Among the hydroxylation reactions in gibberellic acid biosynthesis in plants, the 13-hydroxylation and 3-β-hydroxylation reactions in the GA1 pathway are most sensitive to prohexadione calcium. The 13-hydroxylation reaction is not involved in the GA4 and GA7 pathways. Therefore, prohexadione calcium selectively inhibits the biosynthesis of gibberellins GA1, making it an ideal dwarfing agent.

Prohexadione calcium is a novel plant growth retardant and a late-stage inhibitor of gibberellin biosynthesis. It has low toxicity, no residual residue, and no adverse effects on subsequent crops or the environment.

It inhibits GA1 biosynthesis, controls vegetative growth, and promotes reproductive growth. It can protect existing gibberellin GA4 activity, effectively preventing premature aging in crops. It also exhibits a certain degree of stress resistance, combining growth control, yield increase, and disease prevention.

ABOUT LIMIN CHEMICAL
Yancheng Limin Chemical Co., Ltd.
Yancheng Limin Chemical Co., Ltd.
The story of Limin Group began more than three decades ago, on the fertile soil of China. It was an era calling for agricultural modernization, when food security became a national imperative. Our founding was no coincidence—it was a response to the times: harnessing technology to protect crops, and responsibility to safeguard the granary. From a small team of dozens to a global enterprise spanning five continents, we have always believed that agriculture is not merely an industry—it is the foundation of human survival.
Our R&D centers in China, Europe, South America, Southeast Asia, and Africa employ over 200 scientists, tackling challenges in green synthesis, microencapsulation, and biological pest control. With more than 150 core patents, Limin commands a strong voice in the global agrochemical sector, and our involvement in FAO/WHO international pesticide standards has brought "Chinese innovation" to the center of the world stage.
Today, Limin products serve over 80 countries, protecting more than 6.6 million hectares of farmland. We are not just providers of crop protection—we are guardians of global food security. From the arid lands of Africa, to the highlands of South America, to the rice fields of Southeast Asia—our footprints and commitments are everywhere.
