Grower Field Day: Managing Red Blotch Together

Event Type: Seminar

Location: Beckstoffer Vineyards - 8550 Conn Creek Rd. Rutherford, CA 94573

Date: 4/8/2026

Red blotch is not an issue any grower manages alone. Because viruses move across property lines, effective management depends on coordination, communication, and shared strategy. This Grower Field Day brings neighbors together in the vineyard to explore practical, field-tested approaches to managing red blotch at the block and neighborhood scale.

Hosted at Beckstoffer Vineyards, vineyard manager Brian Hoefgen and viticulturist Jacob Maus, will focus on what collaboration actually looks like in practice, from coordinated monitoring to joint trials and shared decision-making. Researchers and industry experts including Luca Brillante, Malcom Hobbs, and David Andrada will discuss tools growers can use together, including hyperspectral imaging, and lessons learned from neighborhood-based virus response efforts.

Designed to be informal and field-based, this session emphasizes observation, discussion, and real-world application. Attendees will leave with a clearer understanding of how coordinated action strengthens red blotch management and why working with your neighbors remains one of the most effective tools in protecting vineyard health.
