Xemium® fungicide (fluxapyroxad)

Overview

Xemium (fluxapyroxad) distributes through the plant's xylem and also diffuses through waxy cuticle layers, reaching tissues other systemic fungicides miss — particularly leaf tips where stress and disease pressure are greatest. This dual mobility delivers both preventive and curative activity with residual efficacy providing flexible spray timing.
