In 2024 and 2025, a field trial was conducted with ExpressSun® sunflower, hybrid P64 LE185. The experiment was set up in a production field of the Agricultural University-Plovdiv, Bulgaria. The herbicides Express 50 SG (500 g/kg tribenuron-methyl) for the control of dicotyledonous weeds and Pantera 40 EC (40 g/l quizalofop-P-tefuryl) for the management of monocotyledonous weeds were tested. The herbicides used were applied vegetatively, in the phenophase of the fourth-sixth leaf of the crop (BBCH 14-16). Weeding of the experimental field was represented by: Sinapis
arvensis L., Amaranthus blitoides L., Datura stramonium L., Convolvulus arvensis L., Setaria glauca L. and Sorghum helepense (L.) Pers. Weeding with the established weeds is the reason for obtaining a very low average yield from the untreated control (1.05 t ha-1). Herbicidal efficacy was reported on the 10-point EWRS scale. The highest biological grain yield was obtained after the use of Express 50 SG applied in combination with Pantera 40 EC. The 9-point EWRS scale was used to determine the selectivity of the herbicides.
