Protecting Grapevines from Pierce’s Disease
A vineyard health and outreach platform focused on Pierce’s Disease, glassy-winged sharpshooter management, research funding, grower education, and protection of California winegrapes.
Vineyard Protection
Supporting growers with information about grapevine pests, disease vectors, monitoring, research priorities, and practical management resources.
Science, Outreach & Grower-Led Action
The Pierce’s Disease / Glassy-Winged Sharpshooter Board supports activities designed to protect grapevines from Pierce’s Disease and related vineyard threats.
The rebuilt website should focus on clear educational resources for growers, researchers, industry stakeholders, and the public, with sections for disease biology, pest management, research, outreach, assessments, and timelines.
Pierce’s Disease: A Major Grapevine Threat
Pierce’s Disease is associated with the bacterium Xylella fastidiosa. It affects grapevines by disrupting water transport, which can lead to leaf scorch, reduced vine performance, and vine decline.
Cause
Pierce’s Disease is caused by Xylella fastidiosa, a bacterium that lives in xylem tissue and affects water movement in plants.
Transmission
The disease is spread by xylem-feeding insects, especially sharpshooters, including the glassy-winged sharpshooter.
Management
Management depends on monitoring, vector control, research-based guidance, regional coordination, and grower education.
Glassy-Winged Sharpshooter
The glassy-winged sharpshooter, Homalodisca vitripennis, is a highly mobile xylem-feeding insect and an important vector of Pierce’s Disease.
Bridging Science and Vineyard Management
The board’s work centers on supporting research, communicating findings, and helping the vineyard community apply science-based management strategies.
Research Funding
Support for projects focused on disease biology, vector management, detection, and practical control strategies.
Grower Education
Outreach materials, updates, newsletters, videos, and field guidance for vineyard managers and industry stakeholders.
Regional Coordination
Collaboration between growers, researchers, agencies, and industry groups to reduce disease pressure.
Monitoring & Response
Tools and information for tracking pest pressure, identifying risks, and supporting timely management decisions.
