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 have not found a barrier works much. Used to grow them surrounded by a
wooden box structure 2 scaffold boards high and that didn't stop them. Then
we grew in an old large water tank with sides nearly 3 ft above ground and
they still got the carrots. This year only one carrot has shown any sign of
root fly so I think it must have been something else that has done the job,
possibly last winter or the dry spring.
Welcome though.
