Population and species composition of weed under differentiated conditions of weed control method

Abstract

The results presented in this paper were obtained in the field experminent carried out in the years 1999-2001 on a soil a very good rye complex. In this experiment definited number of weeds and their floristic species composition. The application of mixtures herbicides decreased of number of weeds as compared with the number obtained for mechanical control of 397-500% at the beginning of the vegetation and of 180-220% prior to tubers harvest. The herbicides reduced the composition of weed species, moreover.
