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
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
REI: 0-hour, 4-hour when used as a dip or dust
Rootshield Plus is also available in a wettable powder formulation.
Suggested Uses: For control and prevention of major fungal pathogens and resultant diseases on greenhouse and nursery vegetables, herbs, ornamentals, fruits, conifer tree seedlings, various trees, legumes, oil seeds and peanuts. One application will last for approximately 12 weeks, and can be used with a 0-hr REI.
