apple cedar rust hosts

[Post to this category]
From: Dan Niven

I want to plant some narrow, moderate sized (10-15') evergreens as a privacy screen, preferably ones that attract birds. Red Cedar might be good except that I have a few apples that are vulnerable to apple cedar rust. I have not been able to find a comprehensive list of cedars that are hosts. I know the Juniperus species are hosts, but I'd like to know if I will be safe with Thuja or Chamaecyparis. In particular, I was thinking one of the Thuja occidentalis cultivars such as Emerald or Techny would be good. Do you know if these can serve as hosts for this disease? Thanks!
