Incoming Plant Quarantine Intake

Preserve source, inspection, isolation, and testing records for incoming plant material before it is mixed with established plant populations.

Scope

Where this method applies

Use for incoming live plants, cuttings, rooted clones, or other vegetative material subject to a quarantine program.

Frequency

When to run it

Every incoming lot or source event before release into the main plant area.

Preparation

Tools and preconditions

Required tools

  • intake identifiers
  • designated isolation area
  • inspection/magnification tools
  • clean handling supplies
  • testing records when used
  • intake form

Before starting

  • Prepare the isolation area before material arrives.
  • Keep source lots traceable and physically separated as required by the program.
  • Follow local rules and site-specific plant-health requirements.

Procedure

Run the method in order

Step 1

Assign identity

Assign lot/plant identifiers and record source, cultivar/project name as supplied, arrival date, and quantity.

Record: Record traceability information without rewriting source claims as verified genetics.

Step 2

Inspect on entry

Inspect foliage, stems, growing points, media/root zone when visible, and packaging for pest or disease evidence.

Record: Record findings, photos, and any rejected material.

Step 3

Isolate

Move material into the designated quarantine area and avoid shared tools, runoff, contact, or traffic patterns that defeat isolation.

Record: Record quarantine location and start time/date.

Step 4

Monitor and test

Perform the observation and testing plan defined by the site's biosecurity program before release.

Record: Record scouting dates, tests, results, and unresolved findings.

Step 5

Release or reject

Document the authorized decision to release, extend quarantine, treat under an approved plan, or reject/dispose according to site rules.

Record: Record decision, basis, date, and responsible person.

Quality control

Verification checks

Every incoming lot has a unique traceable identity.

Quarantine start and release/rejection decision are documented.

Required scouting or testing records are complete before release.

Evidence record

Fields to preserve

  • source
  • arrival date
  • lot/plant IDs
  • supplied genetics label
  • initial inspection
  • quarantine location
  • scouting/tests
  • release decision
  • decision date
  • notes

Interpretation boundary

Limitations

Quarantine reduces risk but does not prove freedom from every latent or undetectable pest/pathogen; testing capability and release criteria must match the risks being managed.
