60 x Vitax Cabbage Collars Deters Root Flies & Repels Slugs Snails Weeds

PACK OF 60 (2 PACKS OF 30 COLLARS) Vitax Cabbage Collars protect cabbages and brassicas from Cabbage Root Fly. They are simple, efficient and non-chemical, and completely biodegradable. The Cabbage Root Fly can be a serious pest for brassicas. The adult fly lays her eggs by the base of newly planted-out brassicas. When the eggs hatch the maggots burrow into the stems and roots to eat them, killing or severely weakening the plant. Vitax Cabbage Collars work by preventing the adult fly from laying eggs near the base of the plant.
