In the period 2018-2019, the biological efficacy of new herbicides and herbicide combinations for maize was studied in the experimental field of Agricultural University, Plovdiv. The experiment was performed using the block method with DuPont Pioneer hybrid P0216 and included preparations applied in phase 5-6 leaf of the crop. In both experimental years, annual late-spring dicotyledonous species predominate - Amaranthus retroflexus L.,Chenopodium album L., Solanum nigrum L., Xantium strumarium L., Datura stramonium L., Abutilon theophrasti Medic., Portulaca oleracea L. From the perennial weeds 2 species are common - Sorghum halepensе (L.) Pers and Convolvulus arvensis L. The best control of weeding was observed when using the combination of Victus OD - 1250 ml/ha + Cabadex Extra - 300 ml/ha. These results correlate both with the yields obtained from the crop and the physical characteristics of the grain.
