The field mycobiota associated with malt barley was characterized over a period of 2 years, and changes in the mycobiota present on different cultivars were evaluated after treatment with pesticides or no treatment. The study showed that spraying with pesticides did not result in changes in the composition of field mycobiota compared with the pesticide-free barley. The determining factor on the mycobiota was the location. The dominant species on barley was Alternaria infectoria Simmons. The most frequent Fusarium species detected were F. tricinctum (Corda) Sacc. and F. avenaceum (Fr.) Sacc. Results implied an interaction between Alternaria and Fusarium on the surface of the kernels.
