ENVIRONMENTAL FATE

Animals Rapid and extensive metabolism. Plants The principal metabolite in plants is the hydroxymethyl analogue. Soil/Environment Kd 4 (loamy sand, pH 6.5, 1.5% o.m.), 45 (loam, pH 5.7, 3.1% o.m.), 21 (clay loam, pH 7.4, 1.9% o.m.), 22 (silty clay loam, pH 5.7, 4.1% o.m.).                    

Usage: Tricyclazole was introduced in Philippines (1976) by Eli Lilly & Co. (agrochemical interests now Dow AgroSciences). It is a fungicide used mainly for prolonged control of rice 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.
