The Leaf Surface Wetness Duration Home Page
A few years ago, at the 1997 American Phytopathology Society Meeting, a group of scientists held an informal meeting to communicate research on leaf surface wetness. One of the suggestions from this meeting was to construct a web page for exchange of ideas on the subject. The web page is intended for both a general and scientific audience.

If you would like to make a contribution to the pages please send your contribution to Roger Magarey rdm5@cornell.edu before August 1, 1999.
