Speedfol B SP is a powder fertilizer high in boron content. With the special additives inside plants absorb nutrients faster and easier. Besides, product wash-off rate by rain decreased by these additives to increase application effectiveness. Speedfol Foliar range phytotoxicity, scorching risk and possibility of leaf damage is very low compared to other foliar products. When it is applied, it prevents plant nutrition deficiencies and corrects deficiencies quickly if exists.
The polyborate formulation of Speedfol B SP contains 17% boron. Its slightly acidic pH reduces the pH of alkaline water. Boron is a micro element taking an important role at cell wall. At boron deficiencies calcium pectate formation prevented and plant defense system affected badly from this situation. Besides, boron also effective on pollen tube growth and pollen germination so deficiency of boron can cause severe lack of fruit formation or fruit set.
