Not the Grapes! WSDA Searches for Pests in the Wine Grapes
Published on July 15, 2014
The Washington State Department of Agriculture (WSDA) is on the lookout for pests that threaten the state’s wine industry and Concord grapes. The major offenders are several species of moths, and Washington pest control experts with the WSDA are carefully monitoring their populations.
Washington Pest Management Experts on the Hunt
In June 2014, the WSDA set about 1,000 traps throughout central Washington’s major grape-growing regions. Experts check the traps every two to four weeks and will continue to do so until September to determine the establishment of invasive moth species. The destructive pests in question are the Grape tortrix, Grapevine tortrix, European grape berry and European grapevine moths. By monitoring the moth populations in Washington, experts hope to catch and control an infestation before it causes too much damage to its wine industry.
The European grapevine moth first appeared in the U.S. in 2009, when it infested Napa Valley grapes in California. Washington pest control experts are learning from those in California about the behavior of the pests and the most successful control techniques.
