Almeida et al. recently published a review--"Ecology and Management of Grapevine Leafroll Disease"--in the open access journal, Frontiers in Microbiology.

http://www.frontiersin.org/Virology/10.3389/fmicb.2013.00094/abstract

The paper introduces various aspects of GLD biology and ecology, with specific examples from case studies in South Africa, New Zealand, California-USA, and France.

Since the journal is open access, feel free to distribute widely.

The Napa County Agricultural Commissioner's office, in collaboration with MIV Insurance Services, will be holding a seminar on April 10, 2013, 9 -11 am. 

Learn first-hand from staff of the Napa County Agricultural Commissioner:

How do they define a compliant work environment, and how to you provide one? What specific records do the inspections target? What about the use of sulfur dioxide in wineries? 

Attendees will be eligible for 2 hours of Continuing Education credit

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. 

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. Dr. Deborah Golino, FPS director, will also give an update on the Grapevine Red Blotch-associated Virus status of the Classic Foundation Vineyard and the Russell Ranch Foundation. Follow the newsletter link below to the full agenda. 

Register online. The cost is $49 and includes lunch and a wine reception. The event is co-sponsored by the American Vineyard Foundation and the National Grape and Wine Initiative.

Registration is now open for the upcoming Ag Safety Seminar in Spanish to be held March 28, 2013 (8 am - 4 pm). Topics to be covered include pesticide use safety and regulations, heat illness, night work safety, tractor and driving safety.

Follow the newsletter link for full details and to access the registration form. 

Please direct all questions to the Napa County Farm Bureau: 707.224.5403 or info@napafarmbureau.org

Dr. Arturo Calderon, Postdoctoral scholar, USDA and UC Davis has released an instructional video (in Spanish) on the use of the pressure bomb to measure grapevine leaf water potential. 

We hope you will find this video to be a useful training tool.
