Bio Protector is a preparation ideal in horticulture and fruit-farming. It has been specifically formulated to improove the resistance of plants subject to phisical damages (hail) and biotic challenges. Bio Protector contains plant extracts and a specific pool of Vitamins that activate the endogenous mechanism of plant defence, as well as the production of phytoalexins. It improves the natural responses of plants to biotic and a-biotic stresses. Bio Protector is given by foliar spray during the whole vegetative period, every 15-20 days; it makes plants more vital and more resistant thus improving the quali-qualitative yield. It nourishes and strengthens the plant during the final stages of ripening, favouring a better storability of the poroduct.
