Experiments were made in the experimental field from the location Sanzieni, Covasna County, under the conditions of the year 2018 and 2019 and were designed to determine effectiveness of the treatments in combating the pathogen Cercospora beticola of the sugar beet. The biological material was represented by the Damian, Matti, Vangelis and Tatry varieties. Different treatment schemes were tested and efficacy was calculated. The application of the treatments reduced significantlythe attack of cercosporiosis in all beet varieties in the experimental versions. The highest efficacy value of 95.44% was calculated at the Damian variety in 2019 in the Sfera 535 SC (0.35 l/ha) + Bravo 500 SC (1.5 l/ha) + Amistar Gold (0.5 l/ha) experiment.
