At the request of the California Department of Food and Agriculture (CDFA), the National Academies of Sciences, Engineering, and Medicine will convene an ad hoc committee to provide guidance on grapevine disease research to the CDFA Pierce’s Disease/Glassy-Winged Sharpshooter (PD/GWSS) Board. The committee will carry out three interrelated activities.
Activity 1: Review of Proposals Submitted to CDFA PD/GWSS Board
The committee will evaluate research proposals submitted to the PD/GWSS Board in response to a Request for Proposals (RFP). Specifically, the committee will evaluate research proposals on the grapevine red blotch virus (GRBV) and the grapevine leafroll associated virus type-3 (GLRaV-3), their insect vectors, and the diseases they are associated with, using the proposal evaluation and selection criteria developed by the PD/GWSS. The committee will prepare a brief document that describes the proposal evaluation process and a list of projects recommended by the committee for funding, for the board’s consideration. A non-public appendix will contain detailed evaluations of individual proposals.
Activity 2: Critique of CDFA PD/GWSS Board’s Request for Proposals (RFP) and Proposal Selection Process
The committee will provide a review of and recommendations for improving the PD/GWSS Board’s RFP and its proposal evaluation and selection process.
Activity 3: Review of Current Knowledge on Grapevine Viruses, GRBV and GLRaV-3 Research Outcomes/Gaps and Future Research Approach
The committee will review the state of knowledge about the grapevine red blotch virus (GRBV) and grapevine leafroll associated virus type 3 (GLRaV-3) and the management of diseases they are associated with and develop guidance to the PD/GWSS Board in its efforts to support research that leads to a reduction in the spread of GRBV- and GLRaV-3-associated diseases and their economic impacts.
The committee will examine the scientific literature and gather information from experts, plant health practitioners, and grape growers. The committee will explore recent and current research activities on GRBV and GLRaV3 and their insect vectors that are funded by the CDFA PD/GWSS Board.
In its review, the committee will identify the following as they relate to GRBV and GLRaV-3:
The committee will prepare a consensus report with conclusions from its review, describing what is currently known about GRBV and GLRaV-3; what knowledge is needed to improve management of the diseases caused by these viruses; and the committee’s recommendations with respect to a viable approach for supporting research on grapevine viruses.
