Sorghum is a marginal plant in the sowing structure, therefore there is no chemical protection against its weed infestation. The usefulness of herbicides and their mixtures in weed control in maize, a plant related in origin to sorghum, provides the possibility of their use, if their selectivity is demonstrated in this crop. For this reason, before setting up field experiments, three series of biological tests were performed with several herbicides in a greenhouse. On the basis of evaluation of phytotoxic effects of herbicides and their mixtures, four most selective ones were selected for further field trials and applied in two different soil stands: phaeozem and lessive soil. Field experiments were conducted in the years 2009-2011 with randomized block design near Wroclaw. The obtained results indicated that on both soil stands, tritosulfuron + dicamba with an adjuvant was the most effective in selective control of weeds with high proportions of Chenopodium album, Solanum nigrum and Viola arvensis.
