Pest identification
What's eating my jerusalem artichoke 'red fuseau'?
Slugs and snails
Signs: Young emerging shoots bitten off at soil level in spring; irregular holes in young foliage during wet periods.
Control: Apply iron phosphate pellets around emerging growth; hand-pick at night; use grit mulch over planting area in early spring.
Aphids (various species)
Signs: Colonies on upper stem leaves and flower buds in late summer; generally minor on this vigorous, tall-growing plant.
Control: Encourage natural predators; a strong water jet usually suffices; rarely needs treatment as plant outgrows infestations.

Control: Harvest promptly when mature; protect stored tubers in rodent-proof containers; bury wire mesh below the planting bed if voles are present.
