Opis:
Bipolaris sorokiniana is a dangerous pathogen of plants from Poaceae family. A secondary metabolite with carcinogenic properties produced by this fungus is sterigmatocystin. A field experiment with inoculation of the grain of 9 spring barley genotypes with B. sorokiniana No. 36 was carried out in the years 2012–2014 in the Zamość region. Field observations revealed leaf spot caused by B. sorokiniana in all studied genotypes. In 2012, values of the leaf infection index varied from 21.88 (Oberek) to 48.12 (Hajduczek), in 2013 from 25.31 (Skald, Oberek) to 50.00 (STH 7910) and in 2014 from 21.88 (Oberek) to 50.00 (Hajduczek). In the experimental combination with B. sorokiniana, colonies of this fungus in the years 2012–2014 accounted for: 81.22%, 93.11% and 71.78%, respectively, and in control combination: 40.06%, 32.26% and 33.72%, respectively. The chemical analysis of grain of 9 barley genotypes obtained from plants in an experimental combination with B. sorokiniana in 2014, revealed the presence of sterigmatocystin in the genotypes: Hajduczek, Kormoran, Stratus and STH 7910. The sterigmatocystin concentration ranged from 5.39 ng·g–1 (STH 7910) to 67.05 ng·g–1 (Hajduczek). A statistically significant correlation was found between the value of the leaf infection index and the concentration of sterigmatocystin in the grain.

Opis:
Field inoculation experiments were performed during 2015–2017, in south-eastern part of Poland. The pathogenicity of F. crookwellense was estimated based on the kernels yield reduction of 10 selected oat genotypes. Panicles of oat were inoculated with conidial suspension of F. crookwellense strain No. 72 which caused a reduction in kernels yield by 28.54% and kernels number per panicle by 28.07%, compared to the control. The lowest yield reduction, as a result of the panicle inoculation with F. crookwellense, was found in the case of the cultivar ‘Pablo’ (18.73%), while the highest in the case of breeding line POB 961-1344/13 (36.4%) and cv. ‘Kozak’ (34.3%). Statistically the highest average yield reduction was observed in year 2016, when a higher amount of rainfall, especially in July (just after inoculation) and higher temperature, compared to the long-term standard, were observed. During the period between inoculation and harvest, F. crookwellense was able to produce nivalenol, fusarenone X and zearalenone in oat kernels at the average level of 0.065 mg∙kg⁻¹, 0.026 mg∙kg⁻¹ and 0.015 mg∙kg⁻¹ respectively.
