Rootshield® Plus Granules - 40lb bag
RootShield® PLUS, 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 the roots and do not enter the plant tissue.
