Carrot root fly

Bernard · « **on:** August 05, 2009, 22:10 »

I grew carrots in my garden for the first time this year. I thought I would not need to worry about root fly since I am pretty sure that nobody else grows them around here but many of my carrots have been attacked.

A screen of spring onions has not stopped them so I am looking for another solution for next year. I have heard that a barrier of some certain height will discourage them. Can anyone comment on this and if true, tell me what height?

yes a barrier over 18 inches (24 to be safe will reduce the problem, or cover with fleece or enviromesh

yes 2ft should do it

Which is why some folk grow them in old bathtubs....just the right height.

I also thought this idea was brilliant...the enclosure in white plastic sheeting

I've used both vertical sheeting and enviromesh.

Vertical sheeting reduced the incidents by a lot, but with enviromesh, I've not got any. I also find it better for weeding as you can just throw it back and get in there.

I agree with Dave !

For two years I have used a 3 ft high enviromesh barrier and both years I have had root fly. This year I have covered my carrots with enviromesh instead and so far no flies this year

I have a few just over 2 foot high straight sided buckets I've used this year - no fly, and at last............. straight carrots!!!!!

I believe that carrot fly lives on the roots of wild carrotty plants when there are no actual carrots about. So unless you live in a weed free neighbourhood you are liable to get it!

Cheers,

I have been attacked by carrot fly for the last 2-3 years.(not me personally, my carrots!) I went to the expence of buying enviromesh and put up a three foot barrier around the bed, and this year have had the best carrots ever with no carrot fly! The enviromesh lasts for years, and can also be washed in the washing machine if you are that way inclined! I know most people prefer to do things on the cheap, but for me it was a good investment.

Thanks for the replies folks.
I will have to cost out the barrier solution before next year. Probably not economical in the short term.

On the other hand, when I tasted these I realised that I had not tasted real carrots for many years. My offspring also commented on the better flavour.

When I bought my veggie plants off a local nursery owner, he told me about carrot fly (all new to me) and suggested a spray of 'rose away' when weeding the carrots. Not sure if it worked, haven't checked my carrots yet

Did you manage to find and use Rose Away? I can't see it listed on the current pesticides database (though I could just be searching wrongly!!)

Just a general warning to everyone about pesticides - with a product name like that you'd need to check that it had been tested and licensed for use on edible crops, i.e. guaranteed to be safe for consumption.

And even if it is so licensed, you would need to be careful that you complied with the maximum number of applications per crop and time to be left after spraying before harvesting - both stated on the product label.

If you are going to grow carrots,buy yourself some enviromesh,it lasts for years.
Just get some wire hoops or alkathene pipe and use it like a cloche.hold it down at the sides with some bits of wood.
I get three rows in mine and ive got two bits of enviromesh,one of the best �40 i ever spent on my allotment.

We got the spray, but haven't used it. The nursery owner is in his late 70's and before moving up here about 20 years ago, he had a nursery in Bournemouth. We've bought garden plants and shrubs off him for years, he certainly knows his plants, very knowledgeable man, so I just took his advice and bought the stuff, but not used it

Yorkie · « **Reply #14 on:** August 06, 2009, 22:42 »

Even if he knows his stuff about shrubs, I would still check the label out before using it on edible crops. It may not even still be a current pesticide. Obviously I've never met the nursery owner but it sounds as though he might be of the generation of horticulturalists who sprayed anything going.

I'm not organic but the one thing I will always buy organically is carrots because of a report I once read that they absorbed greater quantities of pesticides than other crops. It may well now be a superseded report but I prefer that choice.
