Function and characteristic 

Brassinolide is the sixth major endogenous hormone, characterized by broad-spectrum activity, high efficiency,

strong potency, and low application rates. It exhibits multiple functions: promoting early development, increasing

crop yields, improving quality, enhancing crop stress tolerance, and mitigating pesticide damage and chemical

pollution effects.

1. Plant endogenous substances, high activity, low use concentration, no toxic effect;
2. Different structures of brassinolide have different biological activities;
3. All structures of brassinolide were obtained by chemical synthesis, clear structure, stable source;
4. Broad-spectrum action, physiological performance of both auxin, gibberellin, cytokinin characteristics: promote the development of seedlings; Promote vegetative growth; Promote reproductive growth; Promote fruit coloring and improve fruit quality; Enhance the ability of plant; Alleviate disease and drug damage.
