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.

- 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

ðą How to Care for Moth Orchid to Prevent Fusarium Wilt?
ð§ How to Water
Water when the roots visible through the pot turn a silvery shade. If they are vibrant green, the plant still has enough moisture.
âïļ Lighting
Place it near an east-facing window. If the leaves turn very dark, it needs more light; if they turn yellowish or develop dry spots, it is receiving too much direct sun.
ðŠī Ideal Soil
Use a mix of pine bark, charcoal, and sphagnum moss to ensure the roots can breathe.
