powdery mildew?

I'm new to veg growing as I've only had my allotment (organic site) for a year. I pulled up my shallots and garlic today as the leaves were all yellow and dead, and discovered that they all had a powder on them and were damp looking, which I'm guessing is onion powdery mildew, but may be wrong. I took them all off site to destroy. Do I need to also pull up all the onions (Red Baron) - nowhere near fully grown - growing adjacent to where the shallots were and destroy them, too, and what do I do about the carrots I planted beside the onions (to try to fool carrot fly)?
All guidance appreciated : )

I was going to say leave the disease free ones, then I read this from the RHS
http://apps.rhs.org.uk/AdviceSearch/profile.aspx?PID=743#section3 , which sounds pretty serious, but they don't really give the answer. Leave the carrots, not the same family.
HI Busy-Lizzie
Thank you for the link. No onion family planting for me for 5 years then! Fingers crossed carrot fly don't get the carrots : )
Don't think it's as bad as that. Plant them in a different spot - crop rotation.
I'll give it a go - maybe there was a problem with the same thing in that part of the plot before I got it last year as onions grew fine for me last year in their old spot : )
