Arable Weeds at the Edges of Kettle Holes as Overwintering Habitat for Phytopathogenic Fungi

Weeds in agricultural landscapes can serve as alternate hosts for phytopathogenic fungi and promote the spatial long-term distribution of these fungi. Especially, semi-natural habitats such kettle holes are considered a source fungal pathogens because they permanent habitat various weed species arable lands. In our study, we investigated suitability nine different families at edges 18 two consecutive autumn/winter seasons Fusarium Alternaria. We detected infestation with both genera on every significantly higher abundances second, notably wetter season. Eight were described non-host plants Alternaria Brandenburg, Germany first time. periods, weeds harbored more than Fusarium. The study revealed high diversity community structure up to 12 holes. Grasses showed highest often compared herbaceous plants. Therefore, lands act ecosystem disservice spread diseases surrounding crop fields.
