Sensitivity of Different Chenopodium album L. Biotypes to Metamitron

Nordmeyer, Henning GND

Chenopodium album L. populations were tested for sensitivity to the herbicide metamitron. Sensitivity was assessed by a dose-response relationship and ED50 values. Seeds were collected from single plants in different districts of Germany and in different types of locations (non-agricultural land, fallow land, conventional farming and organic farming). Additional seeds were collected from single plants within a field in a 12-metre grid space. Results were evaluated for different districts and different types of locations and for a single field. There were only small variations in sensitivity at low application rates. Significant differences could be estimated between districts. All Chenopodium album L. populations were sensitive to metamitron. No resistant plants were found.
