EPA REGISTERED & OMRI Listed
Exempt from CT EPA Regulations on K-8 and Municipal Parks!
RootShield® PLUS naturally protects plants from soil-borne diseases such as Phytophthora as well as Pythium, Rhizoctonia, and Fusarium as well as other plant diseases. Easy to mix into media, RootShield PLUS now contains two active ingredients, Trichoderma harzianum Rifai strain T-22 and Trichoderma virens strain G-41. When applied, these microbes colonize plant roots and protect from damping off caused by common soil pathogens. RootShield PLUS also produces stronger root systems that have greater soil exploration and moisture uptake, resulting in better plant quality and marketability. RootShield PLUS is compatible with many commonly used fungicides, fertilizers, insecticides, and herbicides. It is an excellent tool for fungicide reduction and resistance management.
