ACHIEVEMENTS AND PROBLEMS IN THE WEED CONTROL IN BARLEY (Hordeum vulgare L.)

Stated in the literature review gives an idea that many issues are published contrasting views due primarily to the different conditions under which they have conducted experiments and the biological particularities of barley. A serious problem is a resistance and compensatory processes in the weeds. Many authors exported data, which indicate that the barley is different from the common wheat in reaction to some of herbicides, herbicide combinations and reservoir herbicidal mixtures. In the literature there is growing consensus, that periodically have to be make a new mapping of crops and to seek new solutions to chemical control with the changing weed associations.
