The active ingredient in RootShield Granules is a patented fungus, Trichoderma harzianum Rifai strain T22. It is a subspecies of T. harzianum, one of the most prevalent fungi globally, that is designed to incorporate many of the resilient traits of other subspecies found naturally. This fungus attaches to and grows on the new roots, forming a protective barrier against root-rotting pathogens.
