The German Phytomedical Society (DPG) is the largest scientific
association in plant
production in Germany. The Society is membership-based, and its
members are
professionals within the entire field of phytomedicine. Here, we
define phytomedicine as
the science of plant disorders (whether biotic or abiotic), their
diagnosis, management and
control. Phytomedicine deals with all infectious agents that
attack plants, and also covers
damage caused to crops by pests, diseases and weeds. Under our
definition, we
additionally include abiotic disorders such as drought, frost,
flooding, poor drainage,
nutrient deficiency, salt deposition and other soluble mineral
excesses or wind, which may
occur naturally or be man made. Other examples of man-made ‘problems’
include soil
compaction, pollution of air and soil, salt applications on roads
in urban areas, overuse of
pesticides, as well as poor education and poor training of people
working with plants.
The special fields of interest (competences) of the 1,200
individual DPG members clearly
reflect the broad scientific range of disciplines and topics
encompassed by phytomedicine.
In essence, the activities of DPG members are centred around some
20 or so basic
disciplines (e.g. mycology, virology, bacteriology, nematology and
entomology). In a
multidisciplinary sense, 10 core disciplines emerge, covering
important areas such as
disease monitoring, diagnosis, plant protection strategies and
soil management. The extent
of expertise within the DPG membership varies from discipline to
discipline, but all areas
of phytomedicine are covered. Within the membership, there is a
balance between
system-oriented, applied approaches to phytomedicine and basic
research which may or
may not have direct or indirect application. The former constitute
mainly members from
applied research and advisory institutions or organisations, who
seek to provide or support
solutions to plant protection problems, ideally in direct
collaboration with advisors
(practitioners), growers and agricultural companies. The latter
include academic scientists
in federal or university research institutes, whose links to DPG
depend largely on their
individual interests in plant protection issues. Thus, DPG
comprises a community of
experts professionally committed to the achievement and
preservation of both the ‘healthy
