Economic efficiency of plant fungicide protection of five resistant against Cercospora leaf spot sugar beet varieties were tested in two factor experiment on plots in 2013-2014. Sugar beet varieties (Finezja, Gallant, Jagusia, Milton and Pikador) and chemical protection against Cercospora leaf spot (protected and unprotected plots as a control) were factor of experiment. The index of leaf infection by Cercospora beticola and root yield were estimated at the late vegetation time. Economic effectiveness of fungicide protection against C. beticola were calculated using cost coverage ratio (Wpk) and rough profitability index E1 and E2. Protection of resistant sugar beet varieties in low pathogen pressure condition resulted in significant reduction of infection index and root yield increase. Yield increase compensated cost of fungicide protection in case of two among five varieties.
