Well I pulled a radish yesterday to find larve. So do I bin the whole lot? Help I have no idea what to do

Have a look at this recent thread...

So do I pull them all just in case? Am I allowed to plant there again?

I read all the searches but couldn't find a definate solution

They may not be cabbage root fly but bean seed fly.

I knew that bean seed fly attacked more than just beans but a little research has shown that as well as runner and french beans they may also feed on the following.
Beetroot, onions, broad beans, gladioli, cabbage family( especially caulis and radish), lettuce,potatoes, sweetcorn, spinach, courgettes, marrows, pumpkins.

Look at this site for more information. http://www.which.co.uk/documents/pdf/bean-seed-flies-151468.pdf

The flies lay their eggs in the soil and are especially attracted to freshly moved soil with plenty of organic matter. The maggots live on decaying organic matter but if a suitable seed is germinating they will burrow into it. Often what is thought to be onion fly damage is in fact bean seed fly maggots.

Thank you for asking your question, I have learned something new. Rotation will not help. Maybe dig muck in during the Winter rather than the Spring

I would assume its the cabbage root fly because they are a foot away from my cabbages! I do have a divide between them so hope this may be a saving grace if I manage get rid of the larve

Well I pulled the whole bed then used the jeyes fluid. Only a few had been damaged. Was heartbreaking but I would rather try to save the rest of the veg and loose the radish. Shame though cos the kids planted the seeds (thats why so many  )

Fingers crossed caught it early enough
