Among the most efficient precautions for the control of Pyrenophora graminea is the use of fungicides for seed treatment. In this paper was investigated the efficiency of 21 fungicides. The highest efficiency, over 80, had fungicides on the basis of TMTD+carbofix, maneb, guazaintriacetate and Cu-8-hydroxihynolate, and insufficient, under 60, all other fungicides. The highest increase, of 36, was at fungicides on the basis of ipodrion+carbendasim, and high efficience of fungicides on the basis of mercury was not followed by the adequate increase of yield. The lowest yield was achieved at fungicides on the basis of triadimenol, which is the result of higher percentage of disease by Pyrenophora graminea than on the non-treated variant.
