Resistance to photosystem II inhibitors – triazines (atrazine) and triazinones (metamitron, metribuzin) – in Chenopodium album L. is caused by the serine 264 to glycine mutation in the D1 protein. This mutation has been detected in C. album collections from Belgium with unsatisfactory metamitron efficacy in the field and was confirmed in greenhouse resistance bioassays. Incomplete herbicide efficacy in practice can also be caused by reduced uptake due to environmental conditions. Hence, for reliable differentiation and resistance identification, a rapidmethod for mutation detection in the target gene psbA is required.
