International Workshop on Grapevine Downy and Powdery Mildews

The first meeting of the group occurred in 1991 at the Cornell University (Geneva, New York, USA).

Then it moved all around the globe every three/four years depending on the hosting institution: from Freiburg (Germany) in 1994, to Loxton (Australia) in 1998 the GDPM moved back to USA in 2002 when the meeting was organized in Davis (California).

Some European meetings were organized in Italy (2005), France (2009) and Spain (2013) and then, once more in the US, the 8th GDPM was organized in Corvallis (Oregon) in 2017.
