Preventing herbicide drift and injury to grapes

Published March 2004. A more recent revision exists. Please look for up-to-date information in the OSU Extension Catalog: http://extension.oregonstate.edu/catalogDuring the past several years, grape acreages have increased significantly in Washington and Oregon (17 percent and 23 percent, respectively, from 1999 to 2002). Unfortunately, herbicide drift can pose a major threat to the growth\ud and success of commercial grape production adjacent to areas of small grain, hay, grass seed, or corn production. Grapes are especially sensitive to\ud several herbicides used in agronomic crops, pasture, rangeland, forestry, and noncrop areas. When applied to nearby crops, herbicides can drift to vineyards and cause significant injury to grapevines
