摘要
Experiments on site specific weed control in winter wheat were carried out for several years. On all fields a heterogenous weed occurrence of single weed species or grouped species with weed densities above or below thresholds was identified. Weed control was carried out according to the concept of untreated areas. Averaging the results of the winter wheat fields of all years, for grass weeds 16.5 to 55.3 %, for broad-leaved weeds (without Galium aparine) 23.9 to 53,5 % and for Galium aparine 25.5 to 66.7 % were treated with herbicides. So herbicides, man hours and machine work could be saved on a large scale.
