RootShield - Granules

Mix OMRI Listed RootShield Granules in your soil or media before planting to ensure that the developing roots of your new plants are protected against plant pathogenic fungi like:

  • Pythium
  • Rhizoctonia
  • Fusarium
  • Sclerotinia
  • Thielaviopsis
  • Cylindrocladium

The active ingredient in RootShield Granules is a patented fungus, Trichoderma harzianum Rifai strain T22. It is a subspecies of T. harzianum , one of the most prevalent fungi globally, that is designed to incorporate many of the resilient traits of other subspecies found naturally. This fungus attaches to and grows on the new roots, forming a protective barrier against root-rotting pathogens. Once applied to a growing medium, T. harzianum spores germinate and actively seek out roots to pair with and soil-born plant pathogens to feed on. Pathogenic microbes are outcompeted by the T. harzianum and other soil-dwelling microbes resulting in healthier root development and suppression of disease. Less competition for nutrients in the soil allows plants to develop healthier root systems with increased biomass, which leads to improved yields.

The granular formulation of RootShield Granules makes it easy to broadcast when applying and simple to incorporate into growing media. Additionally, the lasting control that RootShield provides will reduce or eliminate chemical fungicide usage. The fungus actively grows with and protects roots if the soil pH is maintained between 4.0 and 8.0 with soil temperatures between 48° and 97° F. It will remain effective for approximately 10-12 weeks and can be re-applied at half the initial rate to extend root protection in the field or when transplanting to a larger container.

 

Suggested Uses: Use in any soil or soilless growing media (compost, bark, coir, or peat, rock wool, hydroton, etc.) before planting. Use to top-dress existing beds and extend root protection by a second application at transplant or after 10-12 weeks. Use with seeds, bulbs, cuttings, and woody propagation before planting for additional fungal control. RootShield Granules can be used in rotation with a variety of insecticides, rooting compounds, growth regulators, and some fungicides.

Use & Instructions

Application Rate:

 

RootShield Granules Application Rates
In-Furrow Soil Treatment Apply RootShield Granules from a granular applicator at the rate of 5-12 pounds per acre. Apply granules using a metering device mounted to deliver granules into the furrow just behind the furrow opener. Apply in furrow at seeding or as a side dress and incorporate into soil.
Greenhouse Planting Mix Amendment Mix RootShield Granules with planting mixes at a rate of 1-1.5 pounds per cubic yard. Thoroughly incorporate into planting mixes during mix preparation or at pot filling.
Nursery Planting Mix Amendment Apply RootShield Granules at the rate of 1-1.5 pounds per cubic yard. For nursery beds, incorporate at a rate of 1-1.5 pounds per 1,000 square feet of bed by raking and tilling. Application of irrigation water will help move RootShield into the soil. If soil is fumigated or sterilized, apply RootShield Granules after treatment.
Trees/Transplants Apply RootShield Granules to the planting hole at a rate of 0.2-8.0 ounces and incorporate into planting soil or soil mix.
