Presentation on spray effect on grapes is Friday

By The Tri-City HeraldOctober 23, 2013 

Grape vineyards in regions of mixed field crops, like the Mid-Columbia, historically have been damaged by herbicides, presumably from a combination of local spray drift and regional off-target movement.

A free public presentation called "Ill Wind for Washington Grapes? Continuing Concern with the Use of Potent Broadleaf Herbicides in Diverse Agriculture," by Vincent R. Hebert is at noon Friday in the Bioproducts, Sciences and Engineering Laboratory, Room 101, at Washington State University Tri-Cities.

BSEL is next to the greenhouses at 2720 Crimson Way, Richland.

The seminar will highlight early and more recent WSU air pollution research and the nature of the plant damage seen throughout the Yakima, Columbia River and Walla Walla valleys.
