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. Drenching RootShield WP wettable powder into the soil protects roots for up to 12 weeks and costs less than 1¢ per 6-in pot.
Note: RootShield G cannot ship to ND!
The next generation of RootShield®, containing two active ingredients (Trichoderma harzianum strain T-22, and Trichoderma virens strain G-41), provides preventative control of major root diseases including soilborne Phytophthora. RootShield PLUS also controls diseases caused by Rhizoctonia, Pythium, Fusarium, Thielaviopsis, and Cylindrocladium – with improved suppression of the aggressive hot-season Pythium (P. aphanidermatum). All this protection for three months with just one easy application.
Use on greenhouse and nursery ornamentals, vegetables, herbs, and fruits. RootShield PLUS grows on the plant’s root system, inhibits and actively attacks pathogens, preventing their establishment and ensuring uninterrupted plant growth.
RootShield PLUS is a preventative biofungicide and should be applied to “clean” (disease-free) plants. Diseased plants should be chemically treated first, since the aggressively growing active ingredients grow on the outside of roots and do not enter the plant tissue.
