Functions
Brassinolide is a new type of green and environmentally friendly plant growth regulator. At very low concentrations, it can significantly increase plant vegetative growth and promote fertilization. Some of its physiological effects include certain characteristics of auxins, gibberellins, and cytokinins:
- Promote cell division and fruit enlargement;
- Delay leaf aging and improve photosynthesis;
- Promote lateral bud germination and induce bud differentiation;
- Improve crop quality and enhance marketability.

Matters needing attention
(1) When applying Brassinolide, the surfactant should be added at a rate of 0.01% of the diluted water to allow the drug to enter the plant body.
(2) Store in a cool, dry place.
