DAMPING OFF IN ONION FARMING IN KENYA
Damping off is a devastating fungal disease caused by pathogens like Pythium, Rhizoctonia, Fusarium, and Phytophthora. It strikes onion seedlings at their most vulnerable, either before they sprout (pre-emergence) or shortly after (post-emergence). Onion Doctor emphasizes that in onion farming in Kenya, where warm temperatures (15–30°C) and high moisture create ideal conditions for fungi, damping off is a persistent challenge.
- Pre-emergence damping off: Seeds rot in the soil, leading to patchy germination.
- Post-emergence damping off: Seedlings develop water-soaked lesions at the soil line, causing them to collapse.

KEY SYMPTOMS OF DAMPING OFF:
PRE-EMERGENCE DAMPING OFF:
- Seeds rot before they emerge from the soil.
- Patchy germination in the nursery or field.
- Soil may appear sunken where seeds were planted.
POST EMERGENCE DAMPING OFF:
- Seedlings collapse and die shortly after emerging.
- Water-soaked, soft lesions at the base of the stem (just above the soil line).
- Affected area becomes thin, constricted, and dark in color (“pinched stem”).
- Seedlings fall over (lodge) and rot.

CONDITIONS THAT FAVOR DAMPING OFF:
- Excessive moisture: Overwatering or poor drainage, common in irrigated farms, fosters fungal growth.
- Contaminated inputs: Infected soil or low-quality seeds spread pathogens.
- Warm temperatures: Kenya’s climate accelerates fungal activity.
- Poor soil aeration: Compacted soils weaken seedling roots.
- Lack of crop rotation: Continuous onion planting builds fungal populations.
MANAGEMENT STRATEGIES OF DAMPING OFF IN ONION FARMING
1. SOURCE CERTIFIED PLANTING MATERIALS: Onion Doctor provides High Quality Onion seedlings.
2.OPTIMIZE SOIL AND DRAINAGE:
- Raised beds: Onion Doctor recommends 15–20 cm high beds to prevent waterlogging.
- Drip irrigation: Collaborate with Onion Doctor for affordable drip kits to control moisture.
3. CROP ROTATION:
Onion Doctor advises rotating onions with crops like maize or beans to disrupt fungal cycles. Avoid planting after garlic or leeks.
4.STERILIZE SOIL AND TOOLS:
- Solarization: Cover soil with clear plastic for 4–6 weeks to kill pathogens with solar heat.
- Fungicide treatment: Onion Doctor recommends use of fungicides and soil treatment.
