Net blotch of barley (Pyrenophora teres Drechsler (anamorph Drechslera teres (Sacc.) Shoemaker)) is common foliar disease of winter barley in Bulgaria. The paper reports results of field experiment performed with triazole fungicides on winter barley variety Nives during 2017-2018 in Agricultural University in Plovdiv. Epoxiconazole 125 g/l was applied in full dose in two applications. Combination of tebuconazole 107 g/l and bromuconazole 167 g/l was used in tree doses of two applications. The aim of the current study was to obtain efficient disease control and to identify the impact of different triazole fungicides. The fungicide efficiency was assessed at the end of April. The trial results show that biologically effective control of barley diseases could be achieved with timely use of lower fungicide dose due to two triazole synergism.
