Here’s a comprehensive guide on preventing mold, pests, and moisture issues in harvested agarwood, which is critical for preserving resin quality:
1. Why Prevention Matters
- Moisture in logs promotes fungal growth and mold, which can degrade resin aroma and reduce commercial value.
- Pests (insects, termites, beetles) feed on wood or lay eggs in resinous sections, causing structural and quality damage.
- Contamination from mold, insects, or moisture reduces oil yield and chip quality.
2. Moisture Control
A. Dry Shade Holding
- Keep harvested logs in shaded, ventilated areas.
- Elevate wood on pallets, planks, or racks to avoid soil contact.
- Avoid direct sunlight, which can crack resin-rich wood.
- Ensure good airflow to prevent humidity accumulation.
B. Gradual Drying
- Dry wood slowly over several days to 1–2 weeks depending on size and resin density.
- Monitor humidity and temperature, especially in tropical environments.
3. Mold Prevention
- Clean rough debris (soil, sawdust) from logs immediately after harvest.
- Remove sapwood that retains higher moisture.
- Maintain air circulation around stored logs.
- Avoid stacking logs too tightly; leave gaps for airflow.
- Optionally, use food-grade fungicidal dust or natural repellents if prolonged storage is necessary.
4. Pest Control
- Inspect logs for insect holes, eggs, or frass before storage.
- Store in elevated, dry areas to prevent termite or beetle infestation.
- Use physical barriers like mesh screens if stored outdoors.
- Consider non-toxic pest repellents or controlled fumigation for long-term storage.
5. Handling & Storage Practices
| Step | Purpose | Tips |
|---|---|---|
| Rough cleaning | Remove soil, sapwood, debris | Soft brush, avoid water contact with resin |
| Elevation | Prevent soil moisture absorption | Pallets, racks, planks |
| Shade & ventilation | Slow drying, prevent sun damage & mold | Open-sided shed or ventilated room |
| Log spacing | Air circulation to reduce humidity | Leave 5–10 cm gaps between logs |
| Inspection | Detect mold or pests early | Daily or weekly check for signs of infestation |
| Optional repellents/fumigation | Long-term protection | Use non-toxic or approved treatments |
6. Additional Tips
- Separate high-resin logs from low-grade or sapwood to reduce mold risk.
- Avoid stacking logs directly on soil; this is the most common source of moisture rise.
- Record harvest date and storage conditions to track potential risk periods.
- Dry slowly—rapid drying can crack wood and reduce resin integrity.
Key Principle: Proper post-harvest care with shade, elevation, ventilation, and monitoring keeps resin-rich agarwood mold-free, pest-free, and high quality, ensuring maximum commercial value.
