Holy Thread Resurrection, Batman!
I went away for 4 days and found my beautiful 2-foot-high garlic plants afflicted by rust. Some quite bad, but it hadn't spread to all of them and the centre of all the plants, ie the newest leaves were rust-free on the whole.
I took myself to the interwebs as I remembered reading somewhere that you could spray with vodka. Alas I didn't have any anyway, but I found a post on a UK gardening forum suggesting spreaying with dilute milk, which I've just done. Also I'm going to take off all the worst affected leaves, which I should have done before wasting milk on them, but hindsight is perfect.
Anyone got any thoughts on this?
One suggestion was to soak the cloves in vodka before you plant them. Too late for me this year.
Other suggestions were that this happens more on sandy soil (which my topsoil is) but I've had it on clay too.
One thing to note is that we had a wet, mild winter with no real frost to speak of. We are very variable here, sometimes a mild winter, sometimes down to -10C/14F.
My ORganic Gardening Encyclopedia wants me to remove and burn all affected bits, suggesting it persists in the soil...?
