Carrot fly

[Pottypotter]

Oh no mine have no chance then along with the carrot fly’s I have planted where couch grass has been growing found out to late that orange wriggly things that live with couch grass burrow through root veg and your best to wait one year before planting there.

I have found in other years that carrots planted next to a row of onions reduces the carrot fly problem, but a fleese covering for the growing life is the most effective

My carrots are under fleece from sowing until the last one is picked.
Ok for a lottie, but not so pretty in a garden! ( if that sort of thing bothers you?!)
I still get some carrot fly, and I go for resistant seed too

Yes they're called wire worms.Not sure how much damage they do to carrots though.

I've just returned to veg growing (after a break of 10yrs to have my own sprouts). I was pretty organic then with cabbage collars & carrot fly barriers but my neighbours used to use chemical deterrants applied to the soil.

Am I correct in assuming that these are now no longer available, & that barriers are the only legal means of fighting off the dreaded fly?

Resistafly, Flyaway carrots. Nonsense!

So. These are my "carrot fly resistant" carrots.

Resistant in what sense of the word?

I had a number of decorative bricks left doing nothing in the garden. So, for the last few
years I have a four brick high wall around my carrot plot and no carrot fly damage. Each year it only takes a few minutes to build.

Carrot fly stay close to the ground so a barrier about 18" TO 24" should in theory keep them out of your cabbage patch.
In my field, I do not use any protective covering on my carrots but grow my carrots in alternate rows with either maincrop onions or spring onions in the rows between them - haven't been bothered with a single carrot fly yet - but I know they are about locally, so this "companion planting" seems to work for me,
