Damping off is a common fungal disease that affects seedlings, causing them to rot and die. It's particularly prevalent in wet and cool conditions, and can be a real nuisance for gardeners. While it can affect a wide variety of plants, it's most commonly seen in tomatoes, peppers, cucumbers, and eggplants.

Environmental favorable factors for pests/Diseases:
Temperature:
-
Pythium: Often thrives in cooler temperatures, between 18°C - 24°C (64°F - 75°F).
-
Rhizoctonia: Can be active across a wider temperature range, from 15°C - 30°C (59°F - 86°F).
Humidity:
-
High humidity: Generally, above 70% relative humidity is considered favorable for damping off fungi.
-
Poor air circulation: This further traps moisture around seedlings, creating a more favorable environment for fungal growth.
Symptoms of Pest/Disease:
- Seedlings fail to germinate or emerge from the soil.
- Seedlings that do emerge become thin and weak.
- Stems become soft and mushy, often with a brown or black discoloration.
