Back to my winter cauliflowers. I haven't been down to the allotment for a bit but when I did go recently , I saw the plants I had treated a few times were no better than before and in fact a lot worse. I fear the beasts have also started on some neighbouring plant.

Is is best to dig up the sickly ones and throw them away and maybe cut any dubious-looking leaves off the other plants? Suggestions please
