What's eating my golden beet?
Beet leaf miner (Pegomya hyoscyami)
Signs: Winding, pale tunnels inside leaves that collapse into brown papery patches when severe
Control: Remove mined leaves immediately; use fine-mesh row cover from sowing to exclude egg-laying adults
Black bean aphid (Aphis fabae)
Signs: Soft-bodied black colonies on stems and undersides of leaves; leaves curl and yellow; honeydew attracts sooty mould
Control: Knock off with water jets; apply insecticidal soap or neem oil spray; avoid over-feeding with nitrogen
Flea beetle (Chaetocnema concinna)
Signs: Fine pin-prick to small round holes across cotyledons and young leaves, slowing establishment
Control: Row cover from germination; intercrop with taller neighbours; kaolin clay barrier spray
Slugs and snails
Signs: Irregular holes in leaves and gnawing on exposed beet crowns, with visible slime trails
Control: Iron phosphate pellets; beer traps; hand-picking after dusk; mulch management to reduce daytime hiding spots

Golden Beet pests — FAQ
What is eating my golden beet?
Golden beet faces the same garden pest complex as other Beta vulgaris varieties: leaf miners, aphids, flea beetles, and slugs. Its yellow flesh does not make it more or less attractive to pests than red beets. Row covers are the most effective preventive tool across all these threats, especially in the seedling stage.
