Late-Stage Induction Timing in Agarwood – Optimizing Resin Densification and Maturation
Late-stage induction focuses on amplifying and densifying resin after early and mid-phase formation. Proper timing ensures maximal resin yield, density, and aromatic complexity without compromising tree health.
1. Definition of Late-Stage Induction
- Occurs after early (FusaPrime™) and amplification (FusaTrinity™) phases
- Involves densification products such as:
- FusaBlaze™ (microbial enzyme-driven polymerization)
- ResinRush™ (abiotic oxidative stress to finalize polymerization)
Goal: Enhance resin density, polymerization, and aroma while avoiding necrosis.
2. Timing Guidelines
| Tree Phase | Post-Induction Interval | Indicators to Proceed |
|---|---|---|
| Early Resin Formation | 2–8 weeks after FusaPrime™ | Light resin streaks, mild aroma, healthy cambium |
| Amplification Phase | 8–16 weeks after FusaPrime™ / 2–6 weeks after FusaTrinity™ | Darkened resin, moderate viscosity, robust sap flow |
| Late-Stage Induction | 6–12 weeks after FusaTrinity™ | Early oxidative polymerization, thickened resin, tree stress minimal |
Key Point:
Late-stage induction is timed based on resin indicators, not calendar alone. Trees must be physiologically ready to handle densification.
3. Factors Affecting Late-Stage Timing
- Tree DBH and age: Larger trees tolerate earlier densification
- Sap flow and cambial health: Must be sufficient to sustain resin polymerization
- Environmental conditions: Avoid extreme wet/dry periods
- Previous resin indicators: Color, viscosity, aroma intensity
- Seasonal window: Optimal in moderate moisture and temperature to enhance oxidative polymerization
4. Practical Protocol
- Assess tree readiness: Confirm sap flow, cambial health, and early resin development
- Select densification product: FusaBlaze™ or ResinRush™ depending on desired polymerization mechanism
- Apply in controlled spacing: Follow DBH-based inoculation points; avoid overlapping stress zones
- Monitor response: Check for resin darkening, viscosity increase, and aroma development over 2–4 weeks
- Adjust follow-up treatments: Repeat if resin density insufficient, ensuring tree remains healthy
5. Farmer-Friendly Summary
- Late-stage induction = resin densification & maturation
- Timing is flexible: based on tree health + early resin indicators
- Goal: High-density, aromatic, polymerized resin with minimal risk
Analogy:
Think of it as the finishing phase of a fine sculpture — carefully applied pressure and polishing make the final product shine.
6. BarIno™ Principle
Controlled late-stage induction maximizes resin density and aromatic complexity.
Proper timing ensures trees are ready, resin is mature enough, and polymerization is optimized, producing high-value agarwood.
