|Subject||Grapevine Leafroll Disease - An Increasing Problem for California Vineyards|
This UC Davis Extension Course was held June 10, 2008 at Freeborn Hall, UC Davis. The links below contain video presentations in an easy-to-use format. No additional software is required.
New research suggest that leafroll disease has become a far more serious problem in California vineyards than previously recognized. The disease was assumed to be largely graft-transmitted under California conditions. Unfortunately, this situation seems to have changed. In the face of what may be a epidemic wave of leafroll spread, experts with leading research programs on leafroll disease and its vectors, mealybugs and soft scale have been brought from around the world to share their knowledge.
The Grapevine Leafroll Disease - An Increasing Problem for California Vineyards seminar was videotaped in excellent quality by UC ANR Communication Services. These Adobe Presenter files do not require any special software to run, but please wait about 12 seconds after clicking a link for the video to begin. Controls for the slides are provided.
