After so many years with carrot fly, and having read up about putting a
polythene barrier 2 feet high, we thought lets give it a try.
The resulting carrots have no evidence of fly damage AT ALL.
The varieties sown were Early Nantes and Autumn King, all sown at the same
time in a very cold day in March this year.
The earlies are only finger size, even now, but the Autumn King are so
good, we were pulling them well before the earlies.
If size matters, the AK's are huge and the earlies are now just right for
earlies ie: finger size.

All said, the barrier method has worked (this year) and we have our fingers
crossed for next year.

Anyone have similars?

I've never had trouble with carrot fly, mainly because the slugs
usually get there first. However, this year I tried growing them
walled around in a box made of of four floorboards. My intention was
to put a perspex lid on it when the slugs discovered the seedlings.
But they never did, and for the first year in many I have a crop,
albeit rather short ones, presumably due to the dry weather and
despite my watering. The only "thinning out" I did was to move some
seedlings around to fill gaps.
