7.3 Late-stage induction timing

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 PhasePost-Induction IntervalIndicators to Proceed
Early Resin Formation2–8 weeks after FusaPrime™Light resin streaks, mild aroma, healthy cambium
Amplification Phase8–16 weeks after FusaPrime™ / 2–6 weeks after FusaTrinity™Darkened resin, moderate viscosity, robust sap flow
Late-Stage Induction6–12 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

  1. Assess tree readiness: Confirm sap flow, cambial health, and early resin development
  2. Select densification product: FusaBlaze™ or ResinRush™ depending on desired polymerization mechanism
  3. Apply in controlled spacing: Follow DBH-based inoculation points; avoid overlapping stress zones
  4. Monitor response: Check for resin darkening, viscosity increase, and aroma development over 2–4 weeks
  5. 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.
