Just dug up my leeks. Found loads of little black things, 3mmx1mm burrowing through the bulbs. Not slugs, they felt crunchy when squashed. Any idea what they are and how to avoid next year please.

Try to mask the onion scent maybe interplanted with carrots or French marigolds around them? Lots of flowers to attract predatory insects,like dwarf sunflowers for the ladybirds. Hope you can salvage some leek pieces?Location : EssexComment

Thanks. No sign of caterpillar like creatures. Here's photo of one on end of a Stanley knife--best I can do with extension tubes and cropping, any more and it blurs. I wonder if these are pupae as no legs and they feel crunchy when crushed.Last edited by DannyK; 10-11-2015, 01:57 PM.Riddlesdown (S Croydon)Comment

That looks distinctly like a pupa and I would therefore think your problem is more likely to be leaf miner than leek moth.A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP. - Leonard NimoyComment

allium leaf miner they are a pain we had them too all in my garlic and in the grandads leeksComment

Sorry for your loss Danny, it's a pupae of the allium leaf miner, ours are ruined too. You can avoid by growing under cover (0.8mm mesh) and I've been reading about bacillus thuringiensis, which occurs in nature but sounds a bit of a faff for anyone wanting to use it in a spray (not that I want to).Location ...

Didn't think they were down your way, but that's deffo ... https://www.rhs.org.uk/advice/profile?PID=643 ... I get them every year
adding to that info, effects can be reduced by Spring planting & crop rotation.

We have this too.
Very frustrating.

Just invest in some fleece or environmesh and keep them covered at all times.Comment

Damn I have the white patches described on the RHS.
Taking some out soon, so now will be doing it with huge apprehensionComment

I had allium leaf miner on my garlic last year and it ruined the crop. I believe the moth has two seasons where it's active - once in spring and then again in autumn - so those are the critical times to cover your crops.Comment

Thank's everyone. I'll be fleecing crop next year and moving it elsewhere.
The RHS's site is poorly laid out. No mention of miner on Leek page. If you plough through the page on the moth a link is buried well down! Didn't spot it first time as I just looked at the pic.Riddlesdown (S Croydon)Comment

Oh dear
It sounds like Allium Leaf Minor, it's traveling up the country at a rate of knots.
Here's the info:

Only thing you can really do is grow under enviro mesh.Blogging at..... www.thecynicalgardener.wordpress.comComment

We've got the same little beasts on ours. First year Ive grown leeks and first time we grew in that spot so rotation wont help much. Mesh/Fleece next year it is then.Comment
