PD/GWSS Board Grants $2.7 Million in New Funding for 17 Research Projects

The PD/GWSS Board recommended $2.7 million in new funding for 17 research projects investigating PD, grapevine viruses, and vectors over the next three years. Sixteen projects are new and one is an expansion of a previously approved project. Additionally, 10 previously approved multi-year projects received continued funding for a little more than $1 million for the fiscal year 2023-2024. The recommendation was approved by California Department of Food and Agriculture Secretary Karen Ross.

“We were pleased with the high number of research proposals we received, especially the increase in projects addressing grapevine viruses,” said Dr. Kristin Lowe, PD/GWSS Board research coordinator. “Every research project the PD/GWSS Board funds brings the winegrape grower industry closer to solutions for the pest and disease problems growers face.”

The Board has invested over $55 million since 2001 in research and outreach to protect vineyards, prevent the spread of pests and diseases, and deliver practical and sustainable solutions. Click to learn more about Board-funded research.
Updates on Nursery Programs

Nursery Regulatory Program:
From January 1 through April 30, 2023, there were 11,180 nursery stock shipments to non-infested areas of the state. Origin county inspectors found four glassy-winged sharpshooter egg masses and one adult in outgoing nursery stock shipments. Destination county inspectors found one viable GWSS life stage during incoming nursery stock inspections, resulting in a Notice of Rejection.

Nursery Stock Approved Treatment Program (ATP):
From January 1 through April 30, 2023, there were 2,996 shipments, consisting of approximately 583,728 plants. No regulatory actions were taken against any ATP nurseries for viable life stages so far this year.
