I'll take a bet it's Flea Beatle. Very bad this year

I've given up trying to grow radishes in the garden due to Flea Beetle. I'm
lucky to get any before they are trashed.
Now I grow radishes in a seed tray of fresh potting compost, keeping the
tray on an old table out of reach of the ground. Has worked thus far. Pity I
can't use the same technique with turnips.
