CAS No: 72962-43-7 

Mode of action: 
Natural plant growth regulator, oligodynamic and rapid, affects specific target tissues that are sensitive to the plant hormone indole-3-acetic acid (IAA). 

Application:
For seed treatment, Brassinolide can help seeds germination, improve seeds vigor. For foliar treatment, it promotes buds formation, keeps flowers and fruit setting, promotes fruit enlargement; improves taste, coloring and shape of fruits; increases rice tillering (shooting), grain filling and grains weight; improve the crops' ability of cold resistance, drought resistance and disease resistance. Mix Brassinolide with other pesticides or fertilizers makes crops relieve from certain phytotoxicity.
