The Julius Kühn Institute (JKI) is the Federal Research Centre for Cultivated Plants in Germany and an independent higher federal  authority in the portfolio of the Federal Ministry of Agriculture, Food and Regional Identity (BMLEH). 

At the 2026 DLG Field Days, our Institute for Plant Protection in Field Crops and Grassland will demonstrate how the reed leafhopper (Pentastiridius leporinus) is raising new challenges for agriculture and plant protection – and what can be done about it now.
