Application

Fluxapyroxad is extensively used in agricultural research for controlling fungal pathogens in cereals, soybeans, and horticultural crops. It demonstrates excellent preventive and curative activity against leaf spot diseases, rusts, and powdery mildews. Researchers utilize this compound to study SDHI resistance mechanisms in fungal populations. The systemic mobility makes it valuable for phloem translocation studies in plants.
