If there is any possibility of maggots from cabbage root fly we use
brassica collars, which you put round the stem to stop the fly laying
eggs there.
Not to be confused with caterpillars from the eggs of cabbage white
butterflies. Use Fleece or fine mesh over the crop, or go round
frequently and squash the eggs or the caterpillars. Or use bacillus
thuriensis(hope that's right)
