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.
