An occurence of Cyperus esculentus in Luxembourg has been reported by a horticultural company in Troisvierges and was confirmed by Jean-Paul Wolff (ATEMO) on 27 August 2024. This is to be seen as the first documented observation of the species in Luxembourg. Tigernut grass is known as an agricultural pest in Switzerland and elsewhere. It reproduces and spreads mainly by root nodules and can lead to considerable yield losses in arable and vegetable farming. The invasive weed has a very high propagation potential. Consequently, every effort should be made to prevent its spread. The potentially concerned stakeholders must be made aware of this problem so that they can intervene at an early stage if necessary.
