Quick orientation
Troubleshooting begins with a precise observation and a map. The engine organises possible categories and discriminating checks, while keeping disease identification and high-risk action behind a qualified-review boundary.
PracticalWhat to notice in the room
- What changed
- Where it appears
- When it began
- What process, climate or handling event preceded it
TechnicalHow the interacting system is interpreted
- Crop logs
- Sensor confidence
- Material traceability
- Photographic record
- Expert or laboratory access

Begin with the pattern you can observe.
This tool organises checks. It does not identify a pathogen or prescribe treatment.
Selected observation
Uneven pinning
Possible categories
- Casing condition
- Water distribution
- Air distribution
- Temperature history
- Crop-surface evaporation
Discriminating checks
- Map the pattern before changing a setting
- Compare casing depth and moisture across affected and unaffected zones
- Compare crop-zone air and temperature history
- Review the timing of watering and climate transitions
Uneven pinning
Observe- Pins cluster in particular rack zones
- Development differs between edges and centres
- The pattern repeats near air or water paths
Checks and prevention
Discriminating checks
- Map the pattern before changing a setting
- Compare casing depth and moisture across affected and unaffected zones
- Compare crop-zone air and temperature history
- Review the timing of watering and climate transitions
Prevention principles
- Verify uniform application and room distribution
- Use mapped observations rather than a single centre-room reading
- Review the complete transition into pinning
Long stipes or weak cap development
Observe- Stem extension is disproportionate to cap development
- The pattern may be room-wide or local
- Timing may align with crop-load or ventilation changes
Checks and prevention
Discriminating checks
- Confirm sensor calibration and placement
- Map readings and morphology by rack zone
- Review fresh-air and recirculation behaviour under crop load
- Compare with unaffected rooms or flushes without assuming one cause
Prevention principles
- Commission airflow with the room loaded
- Maintain traceable crop and climate logs
- Review transitions by stage and flush
Persistent surface wetness or condensation
Observe- Free water remains on the casing or mushrooms
- Condensation appears on cold surfaces
- Wetness is local to particular walls, ducts or rack zones
Checks and prevention
Discriminating checks
- Distinguish applied water from condensation
- Compare surface and air conditions over time
- Inspect local air paths and cold surfaces
- Review door, cooling and humidification events
Prevention principles
- Manage surfaces and air as one moisture system
- Calibrate watering delivery
- Maintain cleanable drainage and envelope details
Dry bubble
Observe- Abnormal tissue or malformed fruit bodies require expert differentiation
- Distribution and progression matter
- Water injury and other disorders may be confused with disease
Checks and prevention
Discriminating checks
- Isolate representative observations
- Record the first affected locations and movement pattern
- Use qualified diagnosis or laboratory support
- Review hygiene, picking and water pathways
Prevention principles
- Clean-to-dirty work sequence
- Tool and personnel hygiene
- Rapid removal under an approved farm procedure
- Verified casing and room sanitation systems
Green mould complex
Observe- Green sporulation is a late visual clue, not a complete species diagnosis
- The point of first appearance may indicate a process pathway
- Affected patches can follow material, water or handling routes
Checks and prevention
Discriminating checks
- Record colour change before disturbance
- Map affected zones and batch links
- Retain traceability for compost, spawn and casing
- Seek laboratory identification when action depends on species
Prevention principles
- Process verification
- Clean material handling
- Room emptying and sanitation
- Batch-level traceability
Sciarid flies
Observe- Adult catches require identification and trend context
- Larval damage may overlap with disease or poor crop development
- Entry and breeding routes should be investigated
Checks and prevention
Discriminating checks
- Use mapped monitoring traps
- Inspect entry points, drains and material flow
- Compare catches with crop stage and room events
- Confirm identification before management
Prevention principles
- Exclusion
- Monitoring
- Waste discipline
- Hygiene zoning and verified sanitation
