Discovery of a common purslane (Portulaca oleracea) biotype resistant to linuron Academic Article

abstract

• Greenhouse and field experiments were conducted to confirm and quantify linuron resistance in common purslane (Portulaca oleracea) collected from a carrot (Daucus carota) field in Imlay City, MI. Preliminary evaluation was made using a flotation test kit to identify resistance to linuron and atrazine. Subsequent greenhouse experiments indicated that this common purslane was resistant to 11.2 kg/ha linuron and 179 kg/ha atrazine. The resistance ratio for linuron was > 300 and was > 400 for atrazine. The resistant common purslane was also highly resistant to diuron, cyanazine, and prometryn but had a low level of negative cross-resistance to bromoxynil. Both resistant and susceptible biotypes of common purslane were sensitive to hexazinone and bentazon.
