Nursery, public green, allotments

Plant protection in nurseries, public green and house and allotment gardens focuses on the entire range of plant pathogens and their management and control on their respective hosts.

One of the key elements of our work is providing consultancy to the German Federal Government, the plant protection services of the Federal states and international associations (for example EPPO). We also cooperate in drafting  expert’s reports and guidelines as well as preparing information material for plant protection services, nursery managers, both public and commercial, and the public.

Our main task is conducting studies in the biology, epidemiology and population dynamics of current and economically significant plant pathogens. This also includes adopting diagnostic systems to business practice. In other words, we are the German reference laboratory for the fungal-like pathogens of the genus Phytophthora. Another focus of our activities is to develop concepts for integrated pest management techniques and sustainable approaches to plant pathogen prevention and management in which the use and promotion of beneficial organisms (such as insects) play an important role.

We deal with a large variety of tasks and are always faced with new challenges. Keeping plants healthy is our biggest commitment.

Significance of the specific subject areas:

Nurseries

In 2012, the area of land used for commercial horticulture and fruit production in Germany was 220,300 hectares. About 9.6 % of this area was dedicated to producing woody nursery plants. In other words, Germany has the third largest area used for commercial woody plant production in Europe. Woody ornamentals account for the largest share (53 % = 11,530 hectares). German woody plant production is mainly focused on raising rootstocks, seedlings and liners, fruit trees, alley trees, roses and forest trees as well as growing Christmas trees.

Public green space

Public green space includes all kinds of green open spaces and landscaped buildings, parks, roadside plantings, and façade and roof greening. In public life, public green space is making an impact on a variety of different factors, such as climate, the environment, public health and living spaces in the cities. In the wake of climate change and scarce financial resources for municipal green maintenance, selecting plants that are suited to local conditions and ensuring their good state of health in extreme locations is becoming more and more important.

Home and allotment gardens

In Germany, around 18 million amateur gardeners cultivate an area of approximately one million square hectares. This figure breaks down into approximately 17 million home gardens and one million allotment gardens. The latter comprise a total area of 46,999 hectares, which translates to 0.25 % of the total German agricultural area. This garden land serves essential functions in society, the environment and climate. Home and allotment gardens are used for self-sufficiency with vegetables and fruits and also as places of recreation and leisure. The demand for plant disease management and control that is easy on the environment and suited for application in house and allotment gardens is constantly increasing.
