Root Maggot Control in Radishes, Onions & Carrots: Diatomaceous Earth & Chickens

Family garden used banned chemical for root maggots in radishes, onions, carrots. Asks replacement.

Organic Solutions

1. Diatomaceous Earth: Dust soil surface & around plants. Abrasive to soft larvae. Reapply after rain.
2. Beneficial Nematodes (Steinernema feltiae): Water into soil at planting. Parasitize maggot larvae.
3. Row Covers at planting: Exclude egg‑laying flies.
4. Crop Rotation: Move alliums/brassicas/roots yearly.
5. Chickens (if allowed): Forage beds between crops — eat pupae/larvae.

Why It's Better Without Chemicals

Healthier soil ecology, no residue, sustainable long‑term.

DE + nematodes + rotation = clean roots.
