FIX is a plant-origin foliar bioregulator developed to support the generative phase of the crop, especially flower formation, fruit setting and early fruit development. Its formulation combines phosphorus, potassium, boron, molybdenum, mannitol and Ascophyllum nodosum seaweed extract.
By supporting metabolic processes involved in flowering and fruit set, FIX helps improve pollen quality, fruit retention, fruit size and uniformity. Its active components are maintained in soluble form to favor rapid uptake by the plant.
