White Mold on Sea Kale: What to Know?
White Mold on Sea Kale (Crambe) is a fungal condition with high severity. Sea Kale has low susceptibility to this disease. White mold (Sclerotinia sclerotiorum) is a devastating fungal disease affecting over 400 plant species worldwide. The fungus produces black, seed-like structures (sclerotia) that can survive in soil f...
Sea Kale is a medium-care plant. Recovery from White Mold takes approximately 21 days with proper treatment.
Unlike most plants, Sea Kale has natural resistance to White Mold. Best treated with preventive measures rather than reactive treatment. Unlike bacterial infections, White Mold on Sea Kale can be managed with organic fungicides.
ð What Does White Mold Look Like on Sea Kale?
- âĒ Sudden wilting and yellowing of leaves
- âĒ Fluffy white mold growth on stems and leaves
- âĒ Water-soaked lesions expanding irregularly
- âĒ Soft, watery rot near soil level
- âĒ Black sclerotia (0.5-1cm) in white fungal mass
- âĒ Grayish-green appearance before wilting
- âĒ Infected stem sections become brittle and tan-colored
â What Causes White Mold on Sea Kale?
- â Fungus Sclerotinia sclerotiorum surviving in soil via sclerotia
- â Prolonged cool, moist conditions (50-68°F/10-20°C)
- â High humidity during flowering period
- â Poor air circulation from dense planting
- â Wind-borne spores from germinated sclerotia
- â Direct contact with contaminated soil
- â Fungus survival on plant debris for 5+ years
ð How to Treat White Mold on Sea Kale?
TLDR: Treat White Mold on Sea Kale with quick treatment (~11 days) or organic (~21 days). Sea Kale has low susceptibility to this disease.
Quick Fixes
Immediate removal
Remove and completely destroy all infected plants. Burn or bag and dispose in trash.
Apply fungicide
Apply systemic fungicide (SDHI or DMI) to neighboring healthy plants preventively.
Reduce moisture
Stop all overhead watering. Use drip only. Improve ventilation/drainage.
Isolate area
Create buffer zone by removing plants within 20-inch radius of infection.
Intensive monitoring
Inspect remaining plants 2x daily for 14 days.
Organic Treatment
Remove infected plants
Carefully remove entire plant without spreading sclerotia. Burn or bury deeply (24+ inches). Do not compost.
Apply biocontrol
Apply Coniothyrium minitans to soil per instructions. This fungus parasitizes Sclerotinia sclerotia.
Improve circulation
Thin adjacent plants to improve airflow. Space plants 12-18 inches apart.
Adjust irrigation
Switch to drip irrigation. Water early morning. Avoid wetting foliage.
Soil solarization
If possible, cover soil with clear plastic for 4-6 weeks in summer (kills sclerotia).
Monitoring
Inspect plants daily for 3 weeks. Remove any new infection immediately.
ðĄïļ How to Prevent White Mold on Sea Kale?
TLDR: Prevent White Mold on Sea Kale with 8 essential preventive care practices.
- â Plant with proper spacing to promote air circulation
- â Avoid excessive irrigation during and after flowering
- â Use drip irrigation instead of overhead sprinklers
- â Remove and destroy infected plants immediately
- â Implement crop rotation with 2-3 years of non-host crops (cereals, corn)
- â Water early in day so foliage dries before nightfall
- â Clean up all crop debris after harvest
- â Avoid planting susceptible species in areas with disease history
