Downy Mildew Field Trials on California’s Central Coast (Fall–Winter)

Why now: From ​November–March, cool, moisture-rich conditions on the Central Coast reliably drive downy mildew—ideal for generating credible efficacy data on real farms.

Quick Specs

• Crops/Hosts: Lettuce, brassicas (e.g., broccoli/cauliflower), onions
• Region & Sites: California Central Coast (cooperating commercial fields)
• Windows: Setup ​Nov–Dec
• Design Options: RCBD/split-plot; 3–4 reps typical; plot sizes scaled to crop
• Endpoints: Incidence, severity, AUDPC, marketability/trim loss, phytotoxicity
• Deliverables: Clean data package, summaries, and photo log; optional demo-plot visuals

Why the Central Coast Works

• Consistent pressure. Seasonal moisture + cool temps promote predictable disease development.
• Field-relevant context. Cooperating commercial farms ensure practical conditions and decision-grade data.

Trial Formats (Pick What Fits Your Stage)

1) Stand-Alone Trials
​For later-stage decisions and label-supporting evidence.

• Full protocol control (rates, timings, MOA rotations)
• Custom design and expanded endpoints
• Robust analysis package for internal milestones

2) Add-On Trials
For early signals or cost-efficient comparisons.

• Insert a single treatment into an existing program
• Shared controls (UTC and grower standard)
• Faster setup and lower cost to learn

​What You Can Expect

• Precision field execution and standardized ratings
• Transparent timelines aligned to the fall–winter cycle
• Actionable analysis, including figures/tables you can lift into internal decks

Next Steps (Windows Are Limited)

• Send your draft protocol for a 48-hour feasibility check
• Hold a plot slot for your preferred window (Nov–Dec setup)
• Decide format: Stand-Alone vs. Add-On based on your objectives
