Phytosanitary
Scouting
on a Phone.

The CRT Requires Full Traceability. FarmAgent Delivers It.

Mexico's phytosanitary framework demands a closed, auditable chain from Mother Garden to Movement Passport — governed by SENASICA, CRT, and reported through SIVEA.

• Plot Registration — Every lot registered with CRT number and Folio Geográfico
• Quarterly Census — 100-plant minimum per lot; 1% sampling above 5 ha
• Bi-Weekly Trapping — Weevil count per trap every 15 days
• SIVEA Upload — Incidence, severity, organism, and actions all required fields
• NOM-006-SCFI-2012 — Tequila specification compliance from field to bottle

Visual Disease Classification — In Real Time

The scout walks the lot in a zig-zag or X pattern. At each plant, they aim their smartphone at the pencas and piña base.

• AI classifies leaf symptoms — circular gray spots, apical yellowing, aqueous necrotic lesions — instantly
• Severity rated 0–4 per SENASICA scale, pre-filled in the logbook with a single confirmation tap
• Core rot check — scout presses the piña base; soft or foul-smelling is flagged as a Focus of Infestation
• 15% threshold auto-trigger — system flags the lot for mandatory intervention when incidence exceeds the SENASICA threshold

Guided Agronomic Tasks — Running in Production.

The same FieldAgent guided task experience that walks an agave scout through the phytosanitary census is already deployed in other crops.

The image shows a blueberry pruning session: FieldAgent's AI Pruning Assistant displays real-time cane-level annotated overlays on the worker's phone — KEEP (green) vs. REMOVE (red/X) — with cane age and estimated yield impact.

Four Economic Pests. One Camera. Instant Classification.

Primary Pests — Economic Impact

• Scyphophorus sp. — entry bore holes, hollow heart. Only pest present year-round — sole target of pheromone traps.
• Strategus aloeus (Rondon) — stem boring, severe root and crown damage
• Asterina mexicana — circular gray spots (mancha gris) on pencas
• Cerambycid (Longhorn Beetle) — larval stem tunneling, secondary infection entry point

Secondary Monitors — Damage Severity

• Fusarium oxysporum — apical yellowing (Wilt) — monitored to prevent field-wide spread
• Erwinia carotovora — aqueous necrotic lesions, soft rot — monitored for severity escalation

Automated Weevil Counts — 3 Seconds Per Trap

Scyphophorus sp. is the only economic pest suitable for pheromone trapping — because it is the only species present in the field year-round. Rondon, Cerambycid, and gray spot must be caught via physical inspection.

• FarmAgent's YOLO model counts every adult weevil in the trap from a single photo — 3 seconds vs. 10+ minutes manual
• Count logged automatically against Trap ID, Plot ID, and Folio Geográfico
• Insects-per-trap/day calculated in real time; threshold alert fires without any data entry

Every Observation — GPS-Pinned, Photo-Verified, Auditable

Every disease rating, weevil count, photograph, and scout identity is anchored to a GPS coordinate in real time — within 3 metres of the affected plant.

• Spatially-explicit inspection record — CRT inspector can see exactly which plants were checked and when
• Infestation Focus visualization — hot zones appear on the map before the scout finishes the lot
• Photo chain of custody — timestamped, scout-attributed, available for CRT audit at any time
• Sample ID generation — date, GPS, collector, and lot ID automatically bundled for lab submission

SIVEA Submission Built During the Inspection — Not After

When the quarterly inspection is complete, FarmAgent calculates incidence automatically and pre-populates the SIVEA required fields:

• Folio Geográfico — GPS-linked plot ID
• Organismo Plaga — scientific name of every detected pest
• Hospedante — Agave tequilana Weber
• Nivel de Infestación — incidence % vs. severity score, auto-calculated
• Acciones Fitosanitarias — intervention logged and linked to CRT agroservices number
