RootShield 1.15% By BioWorks (10 lb)

  • Based on the highly-effective, patented, hybrid fungus Trichoderma harzianum, strain T-22, RootShield Granules protects roots from many pathogens. It blocks and actively attacks pathogens by "eating" them; ensuring uninterrupted plant growth. RootShield Granules is a preventative biofungicide and should be applied to "clean" plants. Diseased plants should be treated with a curative fungicide first since the aggressively growing active ingredient (strain T-22) only grows on the outside and does not enter the plant tissue. RootShield Granules is compatible with fertilizers, algaecides, insecticides, disinfectants, miticides, herbicides, growth regulators, and nearly all fungicides.
