First record of Eriochloa villosa (Thunb.) Kunth in Austria and notes on its distribution and agricultural impact in Central Europe.
Eriochloa villosa is native to temperate Eastern Asia and is an emerging weed in Central Europe. Its current distribution in Central Europe was analyzed using distribution data from the literature and data collected during field trips. In 2019, E. villosa was recorded for the first time in Austria. It was found in a crop field in Unterretzbach in Lower Austria (Eastern Austria). So far, the abundance of E. villosa in the weed communities in Austria and the neighboring Czech Republic is low and thus, its present agricultural impact can be considered limited. However, in Romania and Hungary, the number of records of E. villosa has increased in recent years and it has locally become a troublesome weed. Thus, it is of importance to further monitor E. villosa and to raise awareness among farmers and agricultural advisors.
