Abstract
In a strict field experiment we have studied the influence of different weed control method on the species composition and the number on weeds occurring in a field of four potato cultivars. The application of herbicides decreased the number of weeds, as compared with the number obtained for mechanical control by 1,9–5,1 times at the beginning ofthe vegetation and by 1,5–3,7 times prior to tubers harvest. The herbicides considerably reduced the composition of weed species, moreover.
