Abstract

The consequences of applying prothioconazole-tebuconazole Lamador solution, mefenoxam-tebuconazole Serticor solution and prochloraz-imazalil-triticonazole Turion solution to the daughter seeds of Cedar breed barley were studied. The studied seed fungicides made a statistically significant (p<0.001) influence on the root rot intensiveness on the daughter seeds of barley. The most efficient variants were Turion and Serticor (disease incidence index was decreased by 0.9-9.0 pct, or by 1.0-2.4 times compared to the reference sample). Moreover, the studied fungicides made a statistically significant (p<0.01) influence on the sprout length and the overall root length of the barley. At all the experiment stages, the qualitative mycoflora composition was mainly represented by the plant pathogenic fungi Bipolaris sorokiniana and Alternaria sp. A negligible amount of the fungi Fusarium sp. and Penicillium sp. was detected.
