Pest identification
What's eating my ramsons?
Allium leaf miner (Phytomyza gymnostoma)
Signs: White stippled feeding punctures along leaves followed by maggot mines inside the leaf; secondary rot in bulbs.
Control: Cover with fine insect-proof mesh in spring and autumn flight periods; remove and destroy affected leaves promptly.
Leek moth (Acrolepiopsis assectella)
Signs: Caterpillars tunnel into central leaves, causing wilting and brown papery windows in the foliage.
Control: Use fine mesh (0.8 mm) to exclude adults; pick off caterpillars by hand; apply Bacillus thuringiensis spray on young larvae.
Slugs and snails
Signs: Ragged holes in broad leaves, particularly in shaded damp woodland margins where ramsons thrives.
Control: Hand-pick at night or use iron-phosphate pellets; encourage ground beetles and hedgehogs as natural predators.
