Keep your cyclamen crop healthy and protect it from Fusarium.

Cyclamen plants infected with Fusarium become very yellow. Vascular tissue in the corm turns dark brown to black. Mature plants wilt and die.
To manage this disease, plant sound, disease-free corms in pasteurized media. Discard infected plants.
Keep Fusarium away from plant roots with RootShield® WP, RootShield® Granules or RootShield® PLUS+. Apply this root biofungicide to the growing medium as a preventive measure.
RootShield® contains dormant spores of the effective, and well proven, active ingredient Trichoderma harzianum strain T-22. RootShield® PLUS+ contains two active ingredients (Trichoderma harzianum strain T-22, and Trichoderma virens strain G-41).
When RootShield® WP is mixed with water at the typical application rate of 4 oz/100 gallons, over 100 billion spores are applied to the growing medium in one application. Once RootShield® WP is applied to the growing medium, the spores germinate within 16 – 24 hours. As the mycelium emerges from the spore it immediately starts coiling around the plant’s roots, growing medium particles, and any plant pathogen propagules present. After 24 hours RootShield® can't be leached from the soil mix. RootShield® will grow in a diversity of inorganic and organic growing media from sand, perlite, or clay, to pure peat or bark. RootShield® grows tightly on roots in hydroponics systems, including those utilizing the nutrient film technique where there is no medium.
