I think the first thing to do is make sure its early blight. One of the great
features of Hi-Tunnels is that, because the leaves don't get wet, foliar
blight potential goes way down. In fact, I've never seen foliar blight
(early, late, septoria) in a Hi-Tunnel. The reason why it shouldn't happen is
that the fungal spores need the leaves to be wet for a significant period of
time before the spores can germinate and set up an infection on the leaf. We
get early blight routinely in the field, but never in the tunnels. Is there
someone you could call on the verify that it is early blight?
