Fusarium abundance and diversity and Alternaria abundance on arable weeds at the edges of kettle holes in the AgroScapeLab Quillow in autumn and winter 2018, 2019 and 2020

Fields with winter wheat (preceding crop: maize) were selected to quantify the Fusarium and Alternaria infection in September, October, November 2018 as well as in October, November 2019 and January 2020 at 9 different kettle holes in the AgroScapeLab Quillow each season. At each kettle hole, 3 different arable weeds (the most frequent ones) were selected and sampled for further analyses. Total fungi, fungi of the genus Fusarium and Alternaria and the Fusarium species composition were determined by culture-dependent methods (numeration of colony forming units) from 10 weed pieces from each plant sample. Also DNA was extracted from the dried and ground weed samples, and the abundance of the gene copy numbers of Fusarium and Alternaria was determined by qPCR.
