❓ What Causes White Mold on Garden pea?
- → Fungus Sclerotinia sclerotiorum surviving in soil via sclerotia
- → Prolonged cool, moist conditions (50-68°F/10-20°C)
- → High humidity during flowering period
- → Poor air circulation from dense planting
- → Wind-borne spores from germinated sclerotia

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.
🛡️ How to Prevent White Mold on Garden pea?
TLDR: Prevent White Mold on Garden pea with 8 essential preventive care practices.
- ✓ Plant with proper spacing to promote air circulation
- ✓ Avoid excessive irrigation during and after flowering
- ✓ Use drip irrigation instead of overhead sprinklers
- ✓ Remove and destroy infected plants immediately
- ✓ Implement crop rotation with 2-3 years of non-host crops (cereals, corn)
- ✓ Water early in day so foliage dries before nightfall
- ✓ Clean up all crop debris after harvest
- ✓ Avoid planting susceptible species in areas with disease history
🌱 How to Care for Garden pea to Prevent White Mold?
💧 How to Water
Water regularly so that the soil remains consistently slightly moist, especially during germination and flowering—a lack of water during these stages significantly reduces yield. Avoid waterlogging, which promotes root rot.
☀️ Lighting
Peas require full sun, ideally at least 6-8 hours of direct light per day. In partial shade, they grow more slowly and produce a smaller harvest.
🪴 Ideal Soil
They thrive best in medium-heavy, well-drained soil rich in calcium with a slightly acidic to neutral pH (6.0-7.0). Enrich the soil with compost before sowing.
