I think I have garlic rust in my garden. It seems to affect all varieties of garlic (elephant, hardneck, softneck, travelling, clumping and garlic chives). The onions and leeks seem to be unaffected. Can you confirm it looks like garlic rust? Can you offer advice about treating it, or should I pull it and dump it? I have been cutting off the worst affected leaves and I have been spraying them weekly with a copper sulfide fungicide, with limited success. The spraying seems to be slowing the development, but not preventing transmission and not completely preventing the development of the damage on certain plants.
