It is a line of bio-preparations that contain stabilized microorganisms and that perform crop protection effects against diseases caused by nematodes or phytopathogenic fungi or bio-stimulant and nutritional effects such as nitrogen fixation, phosphorus solubilization and micronutrients. They are characterized by being the only biopreparations that contain an exudate inducer (Exu Root) that ensures the response of the microorganism. They are easily applied to the root, through pressurized irrigation systems.
