    APPLICATIONGS
    Melanin biosynthesis inhibitor (reduction of 1,3,8-trihydroxynaphthalene and vermelone). Biochemistry
    Systemic fungicide, absorbed rapidly by the roots, with translocation through the plant. Mode of action
    Control of rice blast (Pyricularia oryzae) in transplanted and direct-seeded rice at 100 g/ha. Can be applied as a flat drench, transplant root soak, or foliar application. One or two applications by one or more of these methods give a season-long control of the disease. Uses
