Uses
Herbicide.
Definition
ChEBI: A member of the class of 1,2,4-triazines that is 1,2,4-triazin-5(4H)-one substituted by an amino group at position 4, a methyl group at position 3 and a phenyl group at position 6.
General Description
4-Amino-3-methyl-6-phenyl-1,2,4-triazin-5-one, commonly known as metamitron, is a pesticide having low polarity and is hydrophobic in nature. Its pKa value is 2.9.
Agricultural Uses
Herbicide: Metamitron is a selective systemic herbicide that is absorbed through roots and leaves and inhibits photosynthesis. It is used to control grasses and broadleaf weeds in sugar beets and fodder beets. Not currently registered in the U.S. Used in most European countries and having 34 global suppliers .
Trade name
BAY 6676®; BAY-DRW 1139®; DRW 1139®; GALAHAD®; GOLDBEET®; GOLTIX®; GOLTIX® 90; GOLTIX® SUPER; GOLTIX® WG; MM 70®; HERBRAK®; MARQUISE®; SKATER®; TORERO® (metamitron + ethofumesate)
Metabolic pathway
Degradation of metamitron by photolysis is strongly dependent on solvents and oxygen, and no photoreaction is found in methanol, acetonitrile, and hexane, nor in oxygen-free water. In water solution, photolytic degradation occurs and results in the formation of desaminometamitron and a ring-opening polar benzoylacetyl hydrazine (tentatively assigned).
