Common crops affected
- Seedlings
- Vegetable Transplants
- Ornamentals
What is it?
Damping-off is caused by several soil pathogens, most commonly Pythium and Phytophthora, along with Rhizoctonia and Fusarium. They attack germinating seeds and young seedlings, rotting the stem at the soil line. Cool, wet, overcrowded, poorly drained conditions strongly favor the disease.
How to identify it
- Seeds failing to emerge (pre-emergence rot)
- Water-soaked, pinched stems at the soil line
- Toppled seedlings that don’t recover
- Patchy stands, worst in cold wet conditions
Damage and how it spreads
Damping-off can wipe out an entire tray or seedbed quickly, and surviving seedlings are often stunted. Because the pathogens live in soil, water, and reused containers, the disease recurs wherever conditions are wet and crowded. Prevention is far more effective than rescue once seedlings start collapsing.
How to control it
- Use clean, well-draining media and sanitized trays and tools.
- Avoid overwatering; provide good airflow and don't sow too densely.
- Bottom-water and let the surface dry between waterings.
- Apply a protective natural fungicide drench to protect germinating seedlings.

Preventing it next season
Start with clean media and sanitized trays, water carefully, give airflow, avoid overcrowding, and protect seedlings preventively. Healthy soil biology suppresses these pathogens — support it with Charge Bioboost.
