Institute booklet


Vegetables as well as medicinal and aromatic plants are synonymous with healthy living. More than 60 vegetables and 100 medicinal and aromatic varieties are cultivated in Germany. Besides conventional produce, consumer demand for organic products is increasing. Diseases, pests and other stressors can damage the plants, leading to reductions in yield and quality. Against this background, we study the causes of the occurrence and spread of harmful organisms and develop integrated plant protection concepts.

In Germany, vegetables are grown in huge diversity on a total acreage of approx. 115,000 hectares (ha). Crops produced for the fresh food market are mainly asparagus, several cabbage varieties, carrot, onion and lettuce, whereas legumes and spinach are typical for contract farming. Among the crops grown under protected conditions (e.g. in greenhouses), tomato, cucumber and lamb’s lettuce are dominating with an overall area of 1,273 ha. Germany’s degree of self-sufficiency with fresh vegetables is approx. 40%. Organic farming accounts for about 10 % of the cultivation area (trend upwards), and is dominated by carrot and onion production.

The cultivation of medicinal and aromatic plants has a long tradition in certain regions of Germany. Presently, there are approx. 750 companies cultivating more than 100 varieties on an area of 12,300 ha. Main crops are parsley, chamomile, chive, dill, fennel, marjoram and peppermint.

Vegetables as well as medicinal and aromatic plants are grown in various field and greenhouse systems. The procedures range from the small-scale cultivation for farmer’s markets to the production of raw material on an industrial scale for the processing industry.

Plant protection

The different ways of cultivation and the multitude of plant species and varieties require adapted and applicable crop protection solutions. The range of pests and diseases may vary due to changing production methods and climatic conditions, and new species can occur anytime. Therefore the causes of damage must be identified first - be it abiotic factors, pests, fungal or bacterial pathogens. The development of suitable control methods requires the investigation of the biology of the harmful organism. Our research work in these areas and our cooperation in the process of approval of plant protection products enable us to develop sustainable solutions for integrated and organic pest management.
