Tremendous efforts and resources are expended to develop
decision support systems as IPM tools, although many of these
systems have not been adopted as tools to inform management
decisions at the farm level. The intent of this session is to
present current information from multiple perspectives on
why decision support systems, and IPM in general, are or are
not adopted. Speakers will present information on risk from
sociological, economic, and practical grower perspectives
within a context of agricultural systems in developed and
developing countries. Case studies will be presented to
emphasize strategies that should be considered when designing
decision support tools to improve their value to and adoption
by stakeholders.

This session will highlight potato diseases and interactions
among soilborne pathogens. Presentations will include research
results on diseases caused by nematodes, fungi, and viruses.
The session will conclude with a panel discussion on “Societal
and economic ramifications of potato diseases.” This will
encompass various pathogens and will also feature discussion
of sampling procedures for potato cyst nematode.
