Difference in activity: 24-epibrassinolide is 97% active, while 28-homobrassinolide is 87% active. This indicates that 24-epibrassinolide has higher activity among chemically synthesized brassinolides.

Prohexadione calcium is a highly active plant growth regulator that can be used to control the growth and development of many crops and is often used in agricultural production.

How Brassinolide works
Brassinolide is a plant growth regulator that promotes plant growth and flowering and fruiting. Its principle of action is: Brassinolide can stimulate plant cell division and elongation, accelerate cell differentiation and tissue growth.
