Intensive application of herbicides during the time, results in changes of weed flora. In maize seed production, those problems are more visible. Resistant, perennial weed species have been spreading although appropriate herbicide combinations have been used. Floristic content of weeds in maze seed production fields was investigated in this study. The analysis of obtained results points out that the number of weed species as well as the number of their individuals have been considerably decreasing on treated areas. The analysis of distributed species reveals that the participation of perennial species, less susceptible to herbicides, have been increasing in the total weed coverage of crops from year to year. The species Sorghum halepense prevails among distributed species.
