Can anyone recommend a Hispi type cabbage that is white blister resistant and a similarly a late Brussels Sprout?

It makes you wonder: -
Brassica white blister.
Onion white rot.
Broad Bean chocolate spot.
Potato Blight.
Garlic rust.
Leatherjackets
Aphids
Slugs and more slugs.

Nothing like a good old challenge  .

What about onion root fly
Cabbage root fly
allium leaf miner
parsnip moth
greenfly
blackfly
whitefly
butterfly
Sorry I don't know of anything white blister resistant, but I think it is better some years than others. Perhaps depends on the weather.
