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 Redstem Filaree?

TLDR: Prevent White Mold on Redstem Filaree 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 Redstem Filaree to Prevent White Mold?

💧 How to Water

Water moderately and only when the soil has dried out—Stork's-bill tolerates short dry spells much better than waterlogged soil. Once established, natural rainfall is usually sufficient.

☀️ Lighting

Choose a sunny to full-sun location with at least 6 to 8 hours of direct light; the plant blooms significantly less in partial shade.

🪴 Ideal Soil

A well-draining, sandy-loam to stony soil with a neutral to slightly alkaline pH (approx. 6 to 7.5) is ideal. Nutrient-rich, humus-heavy soil is not necessary—Redstem Filaree actually grows better in poor soils.
