do you have herbicide drift damage in your vineyard?

The Food and Environmental Quality Lab at Washington State University has put together a vineyard leaf index scoring system to determine if 2,4-D drift or other phenoxy-type herbicides has caused leaf damage in your vineyard. The website can be accessed here: http://feql.wsu.edu/EB/index.htm, and contains a visual rating scale and several forms that can be filled out to assess and report the damage. For more information, please contact Bruce Olson at WSDA.
