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.
