Sustainable weed management aims at technical, economic, social and environmental sustainability in the short and long term. It contributes to sustainable crop protection and the fulfillment of the EU Green deal objectives, which aim to reduce the use of harmful synthetic crop protection products. The Weed Science research group focuses on sustainable weed management in cultivated and non-cultivated areas. Current research activities include 1) research into sustainable weed management in the black strip of low-stem pome fruit orchards, 2/ the integrated approach to invasive species such as yellow nutsedge on arable land and Japanese knotweed in non-cultivated zones, 3/ sustainable weed management along railways 4) reduction of winter weed problems in organic agriculture via a systems approach.  In addition, in-depth research is being conducted on the use of drift-reducing spray nozzles and techniques , and on hyperspectral detection of toxic weeds and invasive species in the  context of precision agriculture. The management strategies are based on the strength-weakness analysis of the targeted weed species and aim at system approaches in which management methods are combined smartly thus reducing negative environmental impact.
