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 and costs less than 2¢ per 6-in pot.

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
