^Basfoliar® Rhizo Bio SL is a registered biostimulant containing the auxin-equivalent extract of the seaweed Ecklonia maxima and the innovative B-Start, a new Bacillus microorganism suitable for liquid solutions. The algae Ecklonia maxima algae will activate the root system for better exploitation of soil reserves. The result will be a more developed root system, better exploitation of soil reserves and a better nourished plant. The start-up of the vines, or trees in arboriculture, is optimised thanks to the physiological activation of the plants. The B-Start micro-organism will activate the root development and promote the development. The effect of the auxin equivalent provided by the Ecklonia maxima seaweed extracts and supported by the activity of the B-Start micro-organism bacteria activates the physiology and strengthens the vigour of the plants, improves the absorption of nutrients, and strengthens the root system at start-up.
