Screening out grapevine virus spares Napa-Sonoma more than $60 million a year

Providing disease-free grapevines and rootstock to California’s North Coast wine region is more than a good idea — it saves the industry more than $60 million annually, according to researchers at the University of California, Davis.
The findings were reported in a working paper released by the Center for Wine Economics at UC Davis’ Robert Mondavi Institute for Wine and Food Science. The complete paper is available online.
“This analysis places a dollar value on the efforts to prevent the spread of just a single disease in a single grape-growing region,” said Kate Binzen Fuller, the study’s lead author and a postdoctoral scholar in the Department of Agricultural and Resource Economics and Foundation Plant Services at UC Davis. “The overall benefits of such testing and certification are, in fact, dramatically higher.”
Even if growers have to pay a premium for certified, virus-free vines, the study shows that the benefits are between six and 10 times the cost.

Viral threat to grapevines

Viruses and related disease-causing microbes pose a serious threat to agriculture because there are no effective controls available to growers, other than destroying infected plants. In the case of grapevines, viruses typically spread over long distances through the movement of infected plants or the use of infected cuttings and rootstock for propagating new plants.
To prevent the introduction and spread of such viruses in grapevines, several clean-plant centers have been established throughout the United States, in partnership with the U.S. Department of Agriculture, to provide a large inventory of virus-screened plants to agricultural nurseries and growers.
The researchers found that the average annual benefit to a grower from replacing diseased vines in a vineyard was 39 cents per vine or $512 per acre, if noncertified vines or rootstocks were used in both the initial and replacement plantings. The benefit for replanting diseased vines climbed to 55 cents per vine or $727 per acre if certified plant material was used to both plant and replant the vineyard.
Overall, the researchers estimate that, for just grapevine leafroll-3 virus, the vine certification program yields a benefit of between 30 cents and 47 cents per vine, or between $401 and $616 per acre. If all growers in the region were to use certified planting stock, this would translate to a benefit of between $40.4 and $61.8 million per year for the North Coast region. This benefit translates to between 4.8 percent and 7.4 percent of the wine grape revenue for that region.

Pick a Coast to Continue Your IPM Career

Whether you prefer the Left Coast or the Right Coast, there are open IPM jobs worth looking into.

First, at Cornell University, the Northeastern IPM Center is looking for a new director. Like the Western IPM Center, the Northeastern Center is one of four regional centers funded by USDA's National Institute of Food and Agriculture to promote advances in IPM science and promote its adoption in ag, community and land-management settings. The Northeastern Center is very active in urban IPM. The selection process begins in early January. Check out the position announcement.

In California, the UC Extension Service is looking for an IPM advisor to work with county Extension advisors and promote IPM practices throughout the Northern Sacramento Valley. Stationed in Butte, the IPM advisor would cover Butte, Colusa, Yuba-Sutter, Glenn and Tehama counties. The application period closes Dec. 15. See the position announcement.
Good luck!

The Western IPM Center Website is Back Up

The Western IPM Center website at is finally back up and up-to-date. You'll find our new address at the bottom, our new phone numbers on the home page and a new job posting for the Northeastern IPM Center director's position on the News and Announcements page.

Our RFA is also posted and available from the homepage. Thanks for your patience during our move.

The Latest Update on the Website Blackout

The Western IPM Center website was only supposed to be down for a few days while the UC Agriculture and Natural Resource servers were physically relocated to the new building we now all share on Second Street in Davis.

But if you've tried to access over the past 10 days or so, you know that didn't quite go to plan.

The problem, as it's been explained to us, is AT&T's broadband connection to the building isn't connecting, and we don't know if it's a building wiring issue, an AT&T issue or what. The latest update we received was that they were still working on it and hoped to have it fixed by Tuesday. We really hope that's the case and the next post we have to write tells folks know the blackout is over and we're back in business.

There's a Reason No One Likes Moving

Natural light we have. Internet access, not so much...
Our website was supposed to be back up yesterday. It's still down Wednesday afternoon, for which we apologize.

When we were told our office would be moving off of the UC Davis campus into a newly remodeled building, we had no idea that the computer server that hosts the site would be affected. As we moved into the new building yesterday (along with pesticide education programs, county advisors, 4-H folks and others) we were all trying to share a small number of Wi-Fi access points, which went just about as well as you'd expect.

Hopefully the computer folks get the servers up soon and we're back in business. In the meantime,  if you need to download the 2014 Center Grants RFA, please log into the proposal management website to access it. And if you want to visit us in the new digs, stop by the UC ANR Building at 2801 Second Street in Davis. Just be sure to check your email before you get there...

Stating the Obvious

We know it's stating the obvious, but the Western IPM Center website is still down this morning. We thought it would be. Our server should be relocated and the site should be back up tomorrow - Tuesday. Again, we apologize for any inconvenience.
