Speedfol® B SP improves fruitset, increases yield and has a positive effect on crop quality. Boron (B) is essential for cell wall formation (formation of pectin and lignin) and is a structural component of the cell wall. B is required for sugar metabolism and the transportation of sugars. B is needed for proper pollen germination, and an adequate B level in the stigma is necessary for pollen tube growth (key factor for normal seed and fruit development). A lack of B may lead to flower and fruit abortion.
