During the period of 2017-2018 a field study with maize (Zea mays L.) was conducted. The experiment was situated on the experimental field of the Agricultural University of Plovdiv, Bulgaria. Variants of the trial were as follows: 1. Untreated control; 2. Equip OD (75 g/l mesotrione + 30 g/l nicosulfuron) - 2500 ml/ha; 3. Elumis OD (75 g/l mesotrione + 30 g/l nicosulfuron) - 2000 ml/ha; 4. Arigo WG (360 g/kg mesotrione + 120 g/kg nicosulfuron + 30 g/kg rimsulfuron) + Trend 90 - 330 g/ha + 1000 ml/ha; 5. Samson Extra 6 OD (60 g/l nicosulfuron) - 750 ml/ha; 6. Samson 4 OD (40 g/l nicosulfuron) - 1250 ml/ha; 7. Principal Plus WG (552 g/kg dicamba + 92 g/kg nicosulfuron + 23 g/kg rimsulfuron) + Trend 90 - 440 g/ha + 1000 ml/ha; 8. Capreno SC (345 g/l tembotrione + 68 g/l thiencarbazone-methyl + 134 g/l isoxadifen-ethyl) + Mero - 290 ml/ha + 2000 ml/ha. The grown maize hybrid was “Р 9241”. The efficacy of the studied herbicide products against the weeds was evaluated. The highest yield was achieved after the application of Principal Plus WG – 1.53 t/ha average for both years.
