- âĒ Stunted growth and dwarfism
- âĒ Pale green to golden yellow foliage
- âĒ Progressive death of leaves from bottom to top
â What Causes Fusarium Wilt on Java Citronella?

Quick Fixes
Remove Plant
Immediately remove entire infected plant with roots. Dispose in sealed trash (DO NOT compost).
Disinfect Area
Spray area with diluted bleach solution (1:10). Allow to dry.
Apply Biofungicide
If available, immediately apply Mycostop or Trichoderma to affected soil.
Isolate Area
DO NOT plant anything in same area for at least 6 months. Fusarium remains in soil.
Organic Treatment
Immediate Removal
Completely remove infected plant including all roots. Do not compost - burn or dispose in sealed trash.
Tool Disinfection
Clean all tools with 10% bleach solution for 5 minutes. Allow to dry completely in sun.
Soil Solarization
Cover affected area with clear plastic for 4-6 weeks in summer. Heat eliminates pathogens.
pH Correction
Test soil pH. If acidic, add lime to raise pH to 7.0-7.2. Fusarium prefers acidic soils.
Biological Inoculation
Add well-cured compost rich in Trichoderma or apply biological product (Mycostop). Wait 2 weeks before replanting.
Replant with Resistant Varieties
Use ONLY Fusarium-resistant varieties. Check certification. Maintain good drainage.
ðĄïļ How to Prevent Fusarium Wilt on Java Citronella?
TLDR: Prevent Fusarium Wilt on Java Citronella with 9 essential preventive care practices.
- â Use Fusarium-resistant varieties (most effective method)
- â Crop rotation for 3-5 years away from susceptible plants
- â Raise soil pH to 7 in acidic soils
- â Avoid excessive nitrogen in fertilization
- â Use certified disease-free seeds and transplants
- â Clean soil and debris from all tools
- â Improve soil drainage
- â Avoid root injuries during transplanting
- â Soil solarization in infected areas
ðą How to Care for Java Citronella to Prevent Fusarium Wilt?
ð§ How to Water
Water every 4-6 days in warm weather, keeping the soil slightly moist. Avoid waterlogging as wet roots predispose the plant to fungal diseases. During dry spells, increase watering frequency. Always plant in pots or beds with good drainage.
âïļ Lighting
Requires full sun exposure with at least 6-8 hours of direct sunlight per day. In partial shade, growth is reduced and essential oil production drops significantly. Ideal for sunny gardens, south-facing terraces, or open ground.
ðŠī Ideal Soil
Prefers well-draining, sandy-loam, fertile soils rich in organic matter. Tolerates pH between 5.0 and 7.8, ideal range 5.5-6.5. Avoid compacted or poorly draining soils. Mixing sand and organic compost significantly improves substrate structure.
