needlecast

    Is this needlecast on my Tsuga mertensiana?

    Any hemlock people out there seen this before? Could it be Rhizosphaera needle cast? If so, I'm thinking Mancozeb. But it doesn't seem quite right - I can't see the tell-tale little black spores, and it's not just the inner needles - it's all along the branch on several branches.
