BIALGA 15 (Marine Algae)

Marine Algae

BIALGA 15 is a product made up of the 15% of marine algae, i.e. Sargassun, Aschophyllum Nodosum and Laminaria. The product also contains natural plant hormones, enzymes, proteins, vitamines, amino acids, polysaccharides. BIALGA 15 can be used as growth promoter because it stimulates the development of the plants, by enhancing their physiological activity. In general, its use increases the yields, lengthens the period of fruit maturation and storability , improves the germination of seeds, helps root development, enhances plant resistance to stress, reduces significantly chlorophyll deterioration, by improving cell metabolism and decreases salty stress. We advice to use BIALGA 15 together with fertilizers, phytosanitary products and weedkillers, of which it improves the translocation inside the plant.
