Shocka Slug and Cabbage Collars are impregnated with copper to repel slugs and snails, they will also protect brassicas from cabbage root fly PLUS these collars act as a mulch reducing soil moisture loss and suppressing weeds. The female cabbage root fly lay eggs in the soil close to the brassica plant. The egg hatches and the larvae eat the finer roots leaving only a rotting stump. With a collar in place, the female lays eggs on that instead of the soil, so the larvae cannot eat the plants roots. Each Shocka Slug and Cabbage Collar is 13cm in diameter and they come in packs of 20.
