Crop protection in sugar beet cultivation in Germany - situation analysis 2018

摘要

The control of pests is an essential prerequisite to secure crop yield. This situation analysis describes the occurrence of weeds, diseases and animal pests in sugar beet cultivation in Germany and measures to control them. In the EU, the application of integrated pest management is required. One of its key elements is the cultivation of varieties with resistance or tolerance properties, e.g. to Rhizomania or nematodes. Chemical pesticides are also used to control pests, their current and medium-term availability is summarised. In this matter, sugarbeet cultivation is currently facing major challenges, particularly the ban of neonicotinoid seed dressings from 2019 on. The approval status also affects other active ingredients. Furthermore, the emergence of resistant pathogens is crucial for the availability of effective chemical control methods. Consequences for future crop protection in sugar beet cultivation are described. Specific resistance management is essential for the long-term use of the present active substances.
