During 2016-2017 and 2017-2018 a field trial with winter wheat variety “Enola” was performed. The experiment was situated on the experimental field of the Agricultural University of Plovdiv, Bulgaria. Herbicide products with mixed mode of action were evaluated - Osprey Extra, Atlantis WG, Abak and Atlantis Flex. The application of Atlantis WG – 0.50 kg ha-1 + 1.00 l ha-1 showed the highest control against Anthemis arvensis, Papaver rhoeas and Sinapis arvensis. The highest efficacy against the weeds Lamium purpureum and Avena fatua after the application of Abak + Mero – 0.25 kg ha-1 + 1.00 l ha-1 was reported. The treatment with Osprey Extra + Biopower – 0.33 kg ha-1 + 1.00 l ha-1 showed highest efficacy against Lolium rigidum and Galium aparine. The most difficult-to-control weeds were the volunteer of Clearfield® oilseed rape and Veronica hederifolia. The height of the plants, length of the central ear, average number of grains per ear, average grain weight per ear, 1000 grain weight and yields were the highest after the treatment with Atlantis WG – 0.50 kg ha-1 + Biopower – 1.00 l ha-1 and Abak – 0.25 kg ha-1 + Mero – 1.00 l ha-1.
