|National Clean Plant Network Fact Sheet on Red Blotch||
The National Clean Plant Network (NCPN) has released a fact sheet on grapevine red blotch disease.
Identification of the grapevine red bloch-associated virus (GRBaV) is the first step in a process to collect more information on the virus and the disease. Ongoing studies are investigating many aspects of virus and disease, for instance:
1. There is a very good correlation between the presence of GRBaV and symptoms, but this correlation does not prove causality. Studies are investigating the role of GRBaV in red blotch disease.
2. This is a DNA virus that has been tentatively assigned to the family Geminiviridae. As researchers gain more information on the genomic nucleotide sequence the taxonomic classification will be clearer.
3. The virus has been shown to be graft-transmissable. Studies are investigating the potential of vector-transmission of the virus.
4. GRBaV can be detected by a PCR test. Studies are improving detection techniques.
The use of planting material that is free of known pathogens continues to be an important practice to manage diseases associated with viral pathogens, given that once viruses are present in the vineyard there is no known cure.
|Current Wine and Wine Grape Research Conference||
The conference will be held February 21, 2013 at UC Davis. This is a day of 15-minute research presentations given by scientists who have received recent funding from one of the agencies that participate in the UGMVE program.

We hope you will find this video to be a useful training tool.
|New weed control book now available||
Weed Control in Natural Areas in the Western United States is the first comprehensive book to focus on control options for invasive plants in natural areas.

|Grapevine red blotch-associated virus||
Dr. Mysore Sudarshana, USDA-ARS, has released a news brochure intended to provide guidelines to recognize and diagnose grapevine red blotch disease. Follow the newsletter link below to access this brochure.
The red blotch-associated virus does not appear to be of recent origin, but the disease may have escaped attention because symptoms are similar to grapevine leafroll disease.
There is still a lot of research that needs to be done to (1) definitively correlate the virus with symptoms (i.e; Koch's postulates), and (2) to determine mechanisms of distribution. Unpublished results suggest that the virus can be transmitted by grafting. No other mechanisms for dispersal in the vineyard have been identified at this time.
There are many factors that can result in the development of red-leaf symtoms in grapevines. These include abiotic factors such as nutrient deficiencies and overly tight tie-tape that may constrict the vine. Biotic agents such as leafroll-associated viruses and vitiviruses, fungi, and Willamette mites may also result in vines with red leaves. Appropriate laboratory testing, careful observations of symptoms and vineyard conditions can help distinguish between these various factors.
|Virginia creeper leafhopper||
Populations of a newly invasive species, the Virginia creeper leafhopper (Erythroneura ziczac), have been detected in some vineyards in Northern California, from the Oregon border to the Northern Sacramento Valley, Northern Sierra foothills, and Lake and Mendocino Counties.
Thus far, the problem is being reported primarily from backyard vines or organic vineyards. Distribution in the California counties where it has been reported is not yet well understood. Although not yet found in Napa or Sonoma Counties, proximal populations are located in Lake and Mendocino. For additional information on identification of this species, refer to a video prepared by UC Cooperative Extension Advisors.
Damage from this species can be much more severe than Western grape leafhopper, in some cases resulting in complete defoliation when control measures are not properly implemented. In many regions of California, the Western grape leafhopper is under control by natural enemies--a complex of parasitic wasps of the genus Anagrus that attach leafhopper eggs. At this time, Virginia creeper leafhopper (VCLH) eggs do not appear to be parasitized by the species of Anagrus present in California, however a thorough investigation has not occurred. Without effective controls, VCLH populations can reach very high levels, especially in backyard and organic vineyards.
Additional information on Virginia creeper leafhopper will be presented by Dr. Lucia Varela, during a "Pest and Disease Update" that is scheduled for March 6, 2013 at the Yountville Community Center (more details to follow.)
|Current Issues in Vineyard Health||
The "Current Issues in Vineyard Health" seminar will be held Wednesday, November 28, 2012 at the DaVinci Building in Davis, California, from 9:00 am to 4:00 pm.

|Field Day on August 3, 2012||
Registration is now open for our upcoming field day on August 3, 2012 at Inglenook Vineyards, Rutherford.
Soils 101: Characteristics of Napa Valley Soils
Mark Battany, Viticulture & Soils Advisor, UC Cooperative Extension in San Luis Obispo & Santa Barbara Counties
Spanish session: 7:30-9:30 am
English session: 10:00 am-12:00 pm
Mr. Battany will start the day with a lecture on the nature and properties of soils.
