Abstract

Abstract Fusarium spp. are phytopathogens causing fusarium head blight in wheat. They produce mycotoxins, mainly fumonisins, deoxynivalenol, and zearalenone. The study was conducted during two growing seasons (2020 and 2021) at the experimental field and laboratories of the Hungarian University of Agriculture and Life Sciences (MATE). The aim of the study was to determine the influence of growing season, nitrogen fertilisation, and wheat variety on Fusarium infection and mycotoxin production in wheat kernel. Zearalenone was not detected during the two growing seasons and deoxynivalenol was only detected in 2020. The results indicate that nitrogen fertilisation and wheat variety did not have statistically significant influence on Fusarium infection and mycotoxin production. The growing season had statistically significant influence on Fusarium infection and fumonisins production due to higher rainfall in 2021 compared to 2020 during the flowering period when the wheat spike is the most vulnerable to Fusarium infection.
