This review discusses important pests and pathogens that could be associated with the cultivation of new crops in Germany, focusing on quinoa, cannabis, and ginger. As Germany diversifies its agricultural landscape, these crops are gaining popularity due to various factors such as nutritional value, medicinal and recreational uses, and culinary enrichment. The paper highlights the potential risks of introducing and spreading new organisms along with these crops. For quinoa, the main concerns are the oomycete Peronospora variabilis and insect pests such as the moth Eurysacca melanocampta and cutworms. Regarding cannabis, the main pathway for pathogens lies in seed imports, particularly for viruses and viroids. Ginger, typically a tropical crop, is being adapted for greenhouse cultivation in Germany and carries the risk of introducing fungi and bacteria of plant health concern. The objectives of the study are to raise awareness about pest risks, identify specific pathogens and pests associated with each crop, and propose management strategies. The research methodology involved compiling data from literature reviews and databases such as the EPPO Global Database and CABI Crop Protection Compendium. The study emphasises the importance of understanding and managing the ecological and economic impact of cultivating these non-native crops, as some pathogens may remain undetected during initial inspections and could potentially spread to other agricultural systems.
