Usage: Fungicide Tricyclazole is a kind of highly systemic protective triazole bactericides, and can be quickly absorbed by root, stem and leaves of rice. It is mainly used for the control of rice leaf blast and rice panicle blast.
Application:Biochemistry Melanin biosynthesis inhibitor (reduction of 1,3,8-trihydroxynaphthalene and vermelone). Mode of action Systemic fungicide, absorbed rapidly by the roots, with translocation through the plant. Uses 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.
