Slugs (Arion species)
Medium to large slugs feeding on leaves, stems and seedlings in damp conditions.
Arion slugs (including Arion vulgaris and related species) are common in outdoor and protected production. They feed at night on seedlings, leaves, flowers and fruit, leaving rasped damage and slime trails. Biological control with Phasmarhabditis hermaphrodita-based nematode products is effective when soils are moist and temperatures suitable, complemented by habitat management and physical barriers.
