What's eating my salsify 'mammoth sandwich island'?
Carrot fly (Psila rosae)
Signs: Rust-brown larval tunnels in the taproot; less common than on carrots but salsify's Apiaceae relatives share susceptibility
Control: 60 cm upright mesh barrier around the bed; rotate away from carrots, parsnips, and celery; sow after late May to miss the first flight
Slugs and snails
Signs: Seedlings grazed at soil level; shoulder scars on developing roots allow soil bacteria to enter
Control: Iron phosphate pellets around seedlings; keep beds weed-free to reduce moist refuges; hand-pick after rain
Aphids
Signs: Light colonies on leaves; rarely severe, but can transmit viruses in season-long infestations
Control: Crush small colonies by hand; insecticidal soap if persistent; avoid over-feeding with nitrogen
