RootShield Granules is an OMRI listed biological fungicide for root disease control. It grows on roots "shielding" them against root damaging fungi. It can be used for media incorporation - nursery, greenhouse, and vegetables. RootShield releases enzymes that dissolve the cell wall of many fungal pathogens, and promotes a healthier root system increasing root mass potential. One application provides up to 12 weeks of protection.
