The advent of herbicide-tolerant sugar beet varieties opens the way to implementing environment-friendly production systems. In part, this can be achieved through the use of ecologically non-toxic herbi-cides. Much more important in general, however, are the increased possibilities of weed control in sowings with minimum tillage. This not only may allow savings in herbicidal measures, but also offers the chance to employ cultural methods which have positive effects on both beets and environment by at times tolerating some weeds. Possible risks (selection of herbicide-resistant weeds, changes in the weed flora and herbicide-tolerant rogue beets as well as other culti-vated plants becoming weeds) which may arise from planting herbi-cide- tolerant varieties can be largely avoided by rotational measures.
