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

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.
