Target Plus is an innovative concentrate of natural extracts with a high content of brown seawed, particularly of the genus Laminaria. The unique extraction process of the natural matrix of Target Plus has been optimised to obtain an effective formulation, rich in seawed extracts including alginates, reserve carbohydrates, polysaccharides (glucans). The seawed extracts in Target Plus act as signals for the plant to initiate the production of molecules actively involved in endogenous responses to stress. In particular, glucans, due to their unique chemical properties, confer greater mechanical resistance to cell walls.
