This project aims to develop sustainable weeding strategies in sugar beet with minimal or no herbicide use, addressing the loss of active ingredients, risks to non-target organisms, and herbicide resistance. By integrating weed–pest interactions, it supports preventive and curative measures for both weeds and pests. Four work packages (WPs) structure the research. WP1 evaluates mechanical weeding and reduced herbicide regimes in field trials, establishing a management gradient. WP2 examines how weeding strategies affect pest pressure (Lixus juncii, Chaetocnema tibialis) and disease development (viruses, SBR), with emphasis on weeds as pathogen vectors. WP3 investigates whether winter cereals and common weeds act as reservoirs for BchV and BYV viruses. WP4 tests the weed-suppressive potential of companion plants under herbicide-free conditions. By combining these approaches, the project aims to reduce herbicide reliance and advance knowledge of weed–pest interactions, supporting resilient and sustainable sugar beet production.
