Why it matters
Without AI, misdiagnosis, delayed roguing, and missed stock traceability lead to roguing errors, infected lots moving through the system, and certification gaps.
From design to safety
Design
AI guides stock design and sampling rules
AI analyzes historical symptom data and virus vectors to define sampling density, roguing thresholds, and testing cadence for dahlia mosaic and tulip breaking virus. It also outlines seedlot origin tracking, container labeling schemes, and storage zoning to support early containment.

Build
Hardware and data pipelines built
Install leaf sampling kits, microscope imaging, PCR workflow, cold storage, and LIMS interfaces; establish data schemas and sample IDs at planting stock scale. Create barcode-enabled tote tracking, calibrated light sources, and image capture calibration targets.

Operation
Daily screening feeds AI decisions
Capture leaf images, run assays, and compare against thresholds to determine positives, schedule confirmatory tests, and update stock records. Implement daily roguing baskets, mobile app alerts for harvest teams, and automated SOP checklists.

Maintenance
Regular calibration and data hygiene
Schedule periodic calibration, validate assay controls, and purge stale data while maintaining complete stock lineage records. Enforce versioned SOPs, quarterly audits, and secure offsite backups.

Worked example
Detecting mosaic risk before tuberized stock is launched
Illustrative scenario with sample data.
A medium-sized dahlia and tulip nursery screens planting stock for mosaic and tulip breaking virus before distribution to fields.
Signal in
site: Dahlia Mosaic Screening; area: 18 acres; tunnels: 6; samples: 320 leaf punches; data: image() scores, Ct values, timestamps.
System out
Alert: mosaic pattern flagged in 2 samples; action: initiate confirmatory PCR; roguing record updated; stock moved to quarantine.
Human sign-off: Head grower reviews AI flags, approves confirmatory tests, and signs off on roguing plan and stock QC notes.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data collection, set sampling cadence, and establish alert thresholds.
Phase 2
Weeks 5 to 12
Pilot AI-driven screening with limited roguing, refine data flows and reporting formats.
Phase 3
Weeks 13 to 24
Scale to full planting stock, finalize SOPs, and integrate with certification records.
Where people stay in charge
- Decisions about roguing, quarantine, and stock removal must be made by the farm head grower or certified QA lead.
- All actions affecting stock status must be documented in the LIMS and traced to a certified SOP.
- Stock release and quarantine warrants must be signed by the farm owner or designated certification officer.
Questions owners and crews ask
What can AI virus detection do for my dahlia mosaic and tulip breaking virus programs?
AI supports early symptom interpretation, lab test triage, and consistent stock records, enabling faster, traceable decisions while meeting certification standards.
What data should I collect to feed the AI system reliably?
Collect leaf images, Ct values, sample IDs, timestamps, grow area, and cultivation stage to maintain model inputs and traceable results.
How do I handle false positives from AI alerts?
Confirm with a second assay and record the decision in the LIMS, updating thresholds if needed and keeping roguing logs current.
Who signs off on roguing and quarantines in this system?
The head grower or certified QA manager reviews AI recommendations, approves actions, and ensures records meet GLOBALG.A.P. or equivalent standards.
