RootShield^® Granules

Based on the highly-effective hybrid fungus Trichoderma harzianum, strain T-22, RootShield protects roots from many pathogens including Pythium, Rhizoctionia, Fusarium, Thielaviopsis and Cylindrocladium. Within 24 hours RootShield blocks and actively attacks pathogens by “eating” them: ensuring uninterrupted plant growth. One application protects roots for up to 12 weeks.

Incorporated into field soil or container growing media, RootShield Granules grows on the plant’s root system and is compatible in all types of field soil, bark, coir, peat-based and soil-less mixes and will protect plugs, cuttings, liners and all container and field-grown plants.

Sizes: 10lb boxes, 40lb bags, 500lb and 1,000lb bulk bags
