3.4 Introducing spatial risk maps into practice (www.isip.de)
ISIP, the Information System for Integrated Plant production www.isip.de, is a Germany-
wide online decision support system. It has been initiated in 2001 by the German Crop
Protection Services as a common portal, thus achieving synergies by pooling existing
information. Target groups are farmers as well as advisors.
Since information transfer is the primary task of extension services, the system is intended to
make this work more efficient by using modern information technology. Therefore a bi-
directional data flow between the services and the farmers was developed. By combining
general with specific data, recommendations can be refined from regional to individual. The
information is primarily distributed via HTML pages, thus a browser is necessary to use the
system (Röhrig & Sander, 2004).

June 2010. Shown are the infection pressures in five classes (very low [green] to very high
[red]) and the respective spraying intervals in days
In 2010 a new way of presenting results of prognosis models for plant pests and diseases has
been implemented. Using interpolated meteorological data in a high spatial resolution as
input paramters, so-called 'risk maps' are drawn (fig. 5). These maps have several
advantages compared to results representing point information based on single weather
stations:
A risk maps more suitable to identify hot spots and eases the interpretation of the
model's results.
The user does not have to choose a specific weather station, which might even not be
valid for his plant production site.
