Benefits
➤ Provides 10% boron in ethanolamine complexed form, ensuring high solubility, stability, and compatibility in spray solutions.
➤ Exhibits rapid foliar absorption and systemic mobility, enabling efficient boron translocation to meristematic and reproductive tissues.
➤ Plays a key role in cell wall synthesis (pectin formation) and membrane integrity, supporting structural plant development.
➤ Essential for pollen tube growth, fertilization process, and reproductive tissue development.
➤ Facilitates carbohydrate metabolism and sugar transport from source leaves to sink tissues like flowers and fruits.
