Rootshield Granules - 40lb bag
Before planting, choose RootShield® Granules to mix in your soil/media for greenhouse, nursery and vegetable crops. The active ingredient is a unique hybrid fungus, Trichoderma harzianum, strain T-22 that protects roots from many pathogens. Within 24-hours RootShield blocks and actively attacks pathogens by “eating” them; ensuring uninterrupted plant growth. RootShield is a preventative biofungicide and should be applied to “clean” plants. Diseased plants should be chemically treated first, since the aggressively growing active ingredient, strain T-22 only grows on the outside of roots and does not enter the plant tissue. RootShield is compatible with fertilizers, algaecides, insecticides, disinfectants, miticides, herbicides, growth regulators, and nearly all fungicides.
Grows on roots "shielding" them against root damaging fungi. For media incorporation – nursery, greenhouse and vegetables. Rootshield granules release enzymes that dissolve the cell wall of many fungal pathogens this promotes a healthier root system increasing root mass potential. One application provides up to 12 weeks of protection.
