Metamitron is an organic compound used as a selective pre- and post-emergence herbicide in sugar beets.[2][3] It is used in the European Union for weed suppression in sugar beets.[3] Metamitron is marketed under the trade name Goltix by ADAMA in Europe, the United Kingdom,[4] New Zealand, and South Africa.

Metamitron is a triazinone herbicide. It possesses a triazine ring like other organic compounds that use cyanuric chloride as a precursor. It is a modification of the chemical 1,2,4-triazin-5(4H)-one, with methyl, amino, and phenyl group substitutions at positions 3, 4, and 6.[1]

Metamitron is in the HRAC Mode of action Group 5.[5] It functions as an inhibitor of PSII by binding to serine 264 on the D1 protein.[6] Resistance to metamitron has been found in Chenopodium album growing as weeds among sugar beet fields in Belgium, caused by a mutation in serine 264.[2][6]

Metamitron has moderate acute oral and inhalation toxicity.[1]
