Integrated weed management strategies to control herbicide resistant Alopecurus myosuroides Huds.

Alopecurus myosuroides Huds. (blackgrass) is one of the most important weeds in Europe and herbicide resistance is an increasing problem. At the same time, more and more active ingredients are losing their permission and are no longer available for A. myosuroides control. High A. myosuroides infestations result in increasing yield losses. Integrated weed management strategies (IWM) combine different measures to enhance control efficacies, prevent the development of herbicide resistances and secure crop yields in long-term. In this study different integrated weed management strategies and their interaction were investigated. It was aimed to determine solutions to control blackgrass effectively. The combination of crop rotation, soil tillage, delayed sowing times as well as a rotation of herbicide mode of action achieved the best results.
