Propolis is a valid and natural alternative to chemical products to fight the most common phytopathologies. It reflects the perfect union between flora and fauna: bees collect the actives from the plants and they give them back in an enriched form to the vegetal world. Propolis performs its phytostimulant action working on plant metabolism giving strength and reducing weakness to pest attacks. In addition, it works on the physiological process that stimulate blossoming fostering pollination. It has antiseptic, protective and scar healing activities and it can be used in organic agriculture with nourishing and enhancing effects on plant natural defences. It can be used in blossoming since it is not toxic to insect pollinators.
