Cranesbill species achieved a strong expansion with high infestation rates in German arable farming systems in the last years. They evolved from rare to hard-to-control weeds. Crop rotations with a high percentage of winter oilseed rape and maize are mainly affected. Current herbicides show only a limited efficacy against cranesbill species in these crops. Data from field trials and laboratory tests show the potency of chemical control measures in cereals, winter oilseed rape and maize. The experimental results are summarized and recommendations for the chemical control of cranesbill in arable farming discussed.
