The spread of stagonospora blotch in cultivars of spring triticale [Stagonosporozės plitimas vasarinių veislių kvietrugiuose]. – Botanica Lithuanica, 9(4): 385–390

The dynamics of stagonospora blotch (causal agent Stagonospora nodorum (Berk.) Castellani et E. G. Germano) spreading on the varieties of spring triticale ‘Gabo’, ‘Wanad’, and ‘Cargo’ was studied in 2000 and 2001 in Pajūris lowland of Lithuania. Expansion of the stagonospora blotch was determined by meteorological conditions, especially by the amount of precipitation. Under weather conditions unfavourable for the spreading of disease ‘Wanad’ appeared to be most resistant to S. nodorum, while ‘Gabo’ was most resistant to the pathogen when weather conditions were favourable for S. nodorum.
