Black-grass (Alopecurus myosuroides) is one of the most important grass weeds in Bavaria. Chemical weed control with high efficacy is very important in different crops. Crop rotations with more winter cereals, reduced soil cultivation and e.g. harvesting by private contractors caused a higher distribution of black-grass in arable farming regions. Evolution of herbicide resistance was observed during the last 20 years. Black-grass herbicide resistance is well monitored by the official plant protection service of Bavaria. A wide range of resistance tests show the development of resistant black-grass and provide an opportunity for future prospects in resistance dynamics.
