Fruit Copper LQ is a bioactivator which amplifies the action of copper and boron thanks to the natural extracts of brown algae (Ascophyllum spp., Laminaria spp., Fucus spp. and Macrocystis spp.), ensuring optimal nutrition, increased productivity, and a rapid response to biotic stress. The algal extracts are obtained using ALGENFOUR SCE® (Super Cold Extraction) technology, under low-temperature supercritical conditions, which preserve the integrity of bioactive molecules and ensure high concentrations. In particular, these extracts are rich in natural phytohormones (auxins, cytokinins, betaines), polysaccharides, amino acids, and oligoelements; they improve nutrient uptake and transport and optimize plant physiology. Copper (Cu), an essential nutrient required by developing organs, plays an active role in chlorophyll synthesis, enzymatic regulation, and the formation of pigments and carbohydrates, contributing to plant growth and resistance to biotic stress (e.g., pathogenic fungi). boron (B) is a crucial micronutrient for flowering and fruit setting. It is involved in cell division, cell wall formation, and sugar metabolism, promoting better fruit and flower development.
