RootShield Plus is an OMRI Listed and EPA registered biological fungicide designed to prevent and suppress common root-borne diseases in organic growing. It contains two beneficial fungi that deliver an improved range of pathogen control:
- Trichoderma harzianum Rifai strain T-22
- Trichoderma virens strain G-41
The Trichoderma strains in RootShield Plus help eliminate fungal pathogens by colonizing the root systems of plants. This mutualistic relationship boosts biological diversity in the root zone and forms a physical barrier helpful in preventing infection. RootShield Plus provides 3 months of preventive control for the following diseases: Phytophthora, Rhizoctonia, Pythium, Fusarium, Thielaviopsis and Cylindrocladium.
