3-Tier Organic Treatment Ladder
Always start with Tier 1. Move to higher tiers only if lower tiers fail. This approach preserves beneficial insects and keeps costs low.
1
Tier 1: Preventive
Yellow sticky traps
When: Hang at crop height, 1 per 5 m²
Ladybird beetles protection
When: Never spray when ladybirds present — they eat 400 aphids/day
2
Tier 2: Early Treatment
Neem seed kernel extract 5%
When: Spray when population exceeds 10/leaf
Soap solution 2%
When: Insecticidal soap spray on colonies
3
Tier 3: Emergency Intervention
Tobacco decoction 2%
When: Severe infestation, spray in evening
Prevention — Best Long-term Strategy
✓Companion plant dill/fennel to attract ladybirds
✓Yellow sticky traps preventive
✓Avoid excess nitrogen (aphids prefer lush tissue)
