PRO BORO is a corrective agent based on Boron (9%) soluble in water, complexed with triethanolamine. Boron is a nutritive element essential for flowers, fruits and roots development and its accumulation occurs mainly in leaves. Moreover, boron is an essential element involved in the transport and absorption of other nutrients; its deficiency exhibits with necrosis of the vegetative apexes, arrest of the flower buds, development or disruption and blackening of the soft tissues.
