  • carrot root fly devastation

    I just lost 3 rows of beautiful, successively sown carrots to little white maggots- which i can only assume is the dreaded carrot root fly. It was very upsetting .

    I've read lots about making barriers and fences to stop the flys getting to the plants but don't know which method to try first... any ideas?

    I have a piece of fleece 28" high 6 metres long attached to stakes which I erect around my 2x1 metre bed. When finished I can roll it up to re-use.

      My entire carrot bed is covered in Enviromesh over cloche hoops, mainly because that's what I had in the shed. I won't know for sure that it's worked for a while yet - I was late sowing carrots this year.

        im sure i read somewhere that the fly only travels along about 1 inch above the soil so im wondering how tall would the screen need to be . any ones experiences think this is right

          Carrot fly supposedly flies no higher than 12 to 18" and only in May & September. Keep covered throughout these months. I have mine in 30" high boxes then covered in fleece or similar.

            You will find various reports of high high carrot fly fly. I think 18" would be my minimum others say 24" so my fleece barrier is 30". Just to be safe.

              These were part of my second crop pot grown (8 pots in total) and stood on a bench 2' high with no mesh. Everyone was unblemished

                Last year I had some in pots on a wall 3' high that got the fly. I can only assume that they can climb steps which run up the side of the wall into the house. (clever little bleeders)

                  My carrot fly in our courtyard [which had 6 ft high walls to 2 sides, a house to one side a garage to another] got ravaged.

                  I fleece now, from sowing to harvest.

                    I had some in a 3ft high wooden trough last year and they got carrot fly. Like Zazen, I decided the best thing would be to cover the lot. I've been growing veg for quite a few years now, and never had a decent crop of carrots... I'm very hopeful that this is the year I change that

                        I've only ever screened my raised bed grown carrots with 24" high fleece and always (touching wood as I type) had a good crop.
                        I read that carrot fly don't fly higher than 20" but who is it that goes around measuring this and how do they make a living??

                          I have an old wheelbarrow (useless in it's designed purpose) which I filled with compost and then strapped a load of lengths of conduit together so they stand upright. I grew carrots in loo roll centres and then placed them into the conduit tubes and back-filled with some more compost.

                          You have to remember to thin them out otherwise they grow too fat to be removed from the tubes (as I found out to my detriment last week), but they are slug/carrot fly and pest free.
