Patterns of pre-crop glyphosate use and in-crop selective herbicide intensities in Northern Germany

We attribute the differences in pre-crop GBH use and in-crop selective herbicide use to regional production differences. Small to medium proportions of fields with both ploughing for primary tillage and pre-crop GBH use in all districts and most prominent in winter barley, winter wheat and maize indicate a luxurious, easy reducible use of GBH. We propose to promote farms with non- and low-use of GBH as an example of good practice.
