STRONGER ROOTS, FEWER LOSSES AND HOW ROOTSHIELD• PLUS+ G
TRANSFORMS BOXWOOD PRODUCTION AT CANNING
Japanese boxwoods (Buxus microphylla japonica) are widely grown in nurseries but highly
susceptible to soilborne pathogens—especially during hot, humid summers. Diseases like
Phytophthora, Pythium, Fusarium, Rhizoctonia, Cylindrocladium, and Thielaviopsis can cause
major crop losses and inconsistent quality.
RootShield PLUS+ G is a biological fungicide combining Trichoderma harzianum strain T-22 and
Trichoderma virens strain G-41 for broad-spectrum, preventive disease control. Incorporating
RootShield PLUS+ G into potting media during canning provides early root-zone protection and
supports strong root development.
In a recent trial, BioWorks tested RootShield PLUS+ G in 208 potted boxwoods (in the previous
crop, 80% exhibited disease symptoms) to compare its performance against standard fungicide
rotations and untreated control.
