9.3 Timing and Field Protocols for Inoculation

Qualification Level: TESDA NC I – Sustainable Resin Induction
Crop Focus: Agarwood (Aquilaria spp.)
Objective: Apply inoculation at the right time using safe, standardized field protocols to maximize resin formation

I. INTRODUCTION

Resin formation in Agarwood is stress-induced, and inoculation must be carefully timed and executed to ensure tree health, effective microbial colonization, and high-quality resin.
Proper field protocols prevent infections, tree death, and microbial contamination.

II. TIMING OF INOCULATION

FactorBest TimingNotes
Tree age3–5 years (young to mature trees)Seedlings and very young trees are vulnerable; mature trees tolerate controlled stress better
Season / climateEnd of dry season to early rainy seasonModerate soil moisture favors microbial establishment; avoid waterlogged conditions
Tree healthHealthy, well-fertilized, disease-free treesTrees under stress from drought or pests have reduced resin potential
Soil conditionMoist, well-drained, enriched with biofertilizersPre-inoculation irrigation may be applied 1–2 days before injection to optimize microbial activity

III. FIELD PROTOCOLS

1. PRE-INOCULATION PREPARATION

  • Select target trees and mark them
  • Record tree ID, age, and health status
  • Prepare inoculant (BarIno FusaTrinity™, Mycoboost, or agar plug)
  • Check soil moisture; irrigate lightly if too dry
  • Sanitize tools (drills, knives, syringes) to prevent contamination

2. WOUND OR HOLE PREPARATION

  • Drill or cut small, clean wounds at target height
  • Avoid excessive depth to prevent tree stress or structural damage
  • Ensure wounds are spaced to allow resin formation without compromising tree stability

3. INOCULANT APPLICATION

  • Insert inoculant into wound (liquid, paste, or agar plug)
  • Apply biofertilizers or microbial enhancers around root zone to support tree defense
  • Seal wound with wax, biodegradable plug, or clay to prevent contamination

4. POST-INOCULATION CARE

  • Monitor tree moisture; avoid waterlogging
  • Mulch around base to conserve moisture and enhance microbial activity
  • Inspect trees regularly for excessive stress, pests, or infections
  • Record date, method, inoculant type, and tree response

IV. SAFETY AND SANITATION PROTOCOLS

  • Wear gloves and protective clothing
  • Disinfect tools between trees to avoid cross-contamination
  • Handle fungal inoculants carefully; avoid inhalation
  • Wash hands after field operations

V. MONITORING SCHEDULE

Post-Inoculation StageFrequencyObservation
First 2 weeksTwice a weekWound condition, microbial colonization, moisture
1–3 monthsWeeklyTree stress, resin initiation, pest incidence
3–12 monthsMonthlyResin development, tree health, fungal activity

VI. BEST PRACTICES

  1. Always use healthy, well-nourished trees
  2. Apply inoculants during moderate soil moisture conditions
  3. Use minimum wounding necessary to induce resin
  4. Combine with biofertilizers and organic amendments for optimal microbial activity
  5. Maintain record-keeping for traceability and evaluation

VII. TESDA NC I PERFORMANCE STANDARD

Learner must demonstrate ability to:

  • Select the right tree age and season for inoculation
  • Follow field protocols safely and effectively
  • Apply inoculants correctly using chosen system (hole, syringe, paste, frill, agar plug)
  • Monitor tree response and maintain records

VIII. FARMER-FRIENDLY CHECKLIST

☐ Trees healthy, disease-free, and appropriate age
☐ Soil moisture checked; pre-irrigation applied if necessary
☐ Tools and inoculants prepared and sanitized
☐ Wounds or holes made carefully without excessive damage
☐ Inoculant applied and sealed properly
☐ Mulch applied around base
☐ Post-inoculation monitoring scheduled and records updated


Key Takeaway: Following correct timing and field protocols ensures controlled, safe resin induction, improves resin quality, and integrates smoothly with biofertilizer use, irrigation, and organic soil management.
