Prom winter wheat and winter triticale stems with distinct disease lesions 23 isolates of eyespot agent - Tapesia yallundae fungus were obtained. Stems ere collected in 1999-2001, from no-treatment and protected with fungicides fields, which were situated in three provinces of Poland (małopolskie, mazowieckie, śląskie). Obtained isolates were c1assified on the basis of morphology on PDA, sporulation on water agar and sensitivity to carbendazim and prochloraz. 51 isolates 41,5% of a11) represent R- growth type of fungus. To this type belong 28% 71% strains obtained from wheat and triticale stems, respectively. Only seven isolates of R-type fungus (i.e. 13,7%) were resistant to carbendazim. These strains originated from two protected with carbendazim winter wheat field s and two, rotected winter triticale crops. All isolates of R-type were sensitive to prochloraz. This compounds appears in vitro more effective than flusilazole, propiconazole and azoxystrobin.

In the years 2001 and 2002 at the Institute of Plant Protection Branch in Sośnicowice research work was performed on seed treatment with fungicides against leaf diseases of spring wheat cv. Ismena caused by pathogenic fungi: Blumeria graminis, Phaeasphaeria nodorum, Puccinia recondita i Pyrenophora tritici-repentis. Two variants of protection were included in the experiment: seed dressing with fungicides or seed dressing and single application of foliar spray at GS 49. At early growth stages of spring wheat a very high biological activity against powdery mildew, septoria leaf spot, brown rust and tan spot was recorded for seed dressing containing triticonazole+prochloraz. In the case of triadimenol+imazalil+fuberidazole only a weak, but long-lasting effect against brown rust and septoria leaf spot was observed. Leaf infection as well as 1000 grain mass and yield, in the experimental combination with using triticonazole+prochloraz were on the same level as in the experimental variant where after seed dressing with triadimenol+imazalil+fuberidazole plots were sprayed with tridemorf+epoxykonazole at GS 49. It was concluded that seed dressing preparation containing triticonazole+prochloraz constituted a good base for protection of spring wheat against foliar diseases.
