14-Hydroxylated Brassinosteroid+Thidiazuron 0.16% SL

14-Hydroxylated Brassinosteroid + Thidiazuron 0.16% SL is a high-performance soluble liquid plant growth regulator, combining two complementary active ingredients-14-Hydroxylated Brassinosteroid, a natural brassinolide analogue belonging to the sterol class, and Thidiazuron, a heterocyclic aromatic urea with potent cytokinin-like activity. This synergistic formulation provides comprehensive regulation of plant growth and development, including promotion of cell division and elongation, enhancement of photosynthetic efficiency, improvement of stress tolerance, and significant increase in yield and quality.

With rapid absorption and systemic translocation, the product delivers visible growth promotion within days and sustained effects throughout the crop growth cycle, making it an ideal solution for modern crop production programs.

The SL formulation ensures:

• Excellent water solubility and rapid dissolution
• Easy handling and tank-mix compatibility
• Consistent performance across diverse crop types

This plant growth regulator exerts its effects through two complementary mechanisms:

• 14-Hydroxylated Brassinosteroid acts by promoting cell elongation and division, regulating leaf morphology, altering cell membrane potential and enzyme activity, enhancing photosynthesis, and promoting the biosynthesis of DNA, RNA, and proteins, thereby improving plant tolerance to environmental stress. As a natural brassinolide analogue derived from rapeseed pollen and beeswax, it exhibits broad-spectrum physiological activity with extremely low usage rates.
• Thidiazuron possesses extremely strong biological activity-hundreds of times higher than general cytokinins in inducing plant cell division. It relieves gene repression, opens DNA and RNA coding, triggers the synthesis of related enzymes and proteins, coordinates the secretion of plant endogenous hormones, and induces the expression of plant systemic acquired resistance (SAR) genes.
• Synergistic combination: The two components work synergistically to achieve comprehensive growth regulation-promoting both cell division and elongation, enhancing photosynthetic capacity and stress tolerance, delaying plant senescence, improving yield and quality.

Key characteristics:

• Dual-component synergistic action → comprehensive growth regulation
• Systemic movement within plant
• Rapid uptake and rainfastness
• Low toxicity and environmentally compatible

Key Advantages
