It's the overwintering that's the problem which allows the rust to survive and infect new plants. Don't overwinter anything this year and you'll have a better chance of being clear next year.
Does the fungicide mix (Edd) work on onion neck-rot? It devastated my onions and leeks last year, first time I've ever had a problem. There are no commercial fungicides available for food crops, only roses.
