The paper aimed to present alternative against the pathogen Pyrenophora teres (anamorph Drechslera teres) which parasitizes barley crop in western parts of Romania even beginning with late autumn period, observing the evolution and symptoms spreading of this fungus. Across the world, Pyrenophora teres causing the net blotch of barley is regarded as the major foliar disease in Hordeum vulgare L. Throughout its two form of Phyrenophora teres, however different from genetical point of view, P. teres f. sp. maculata and P. teres f. sp. teres causes economic losses by reducing yield and grain quality and poor emergence in area with a high biological pressure of the pathogen. The trial extends for two years (2019-2020, 2020-2021) in the same area of cropping (monoculture system) using same seed treatment list and following the seed-borne cereal fungi assessment protocol [(EPPO 1/19 (4)]. Trial setup consisted in complete randomized blocks, 6 treatments like fludioxinil, fluxapyroxad and mixture, every plot measuring 10 m2 and observations performed an al plants/1 m in length sample. When treated with two active ingredients the result obtained exerts an efficacy up to 98%, maintained in both trial years compared with the untreated plots where the pathogen was well established.
