Northwest and Allee Research and Demonstration Farm
The focus of the organic Allee Demonstration Garden in 2001 was to conduct a fourth-year trial on the use of copper wire in tomatoes for disease management, the most important problem in organic tomato production. There are numerous reports concerning successful use of copper wire and other organically approved methods (such as spraying with hydrogen peroxide) from growers nationwide. Results from the 1998 and 1999 Allee Demonstration Garden copper wire trials showed increased fruit production from heirloom tomato plants containing a copper wire insert.
