Is this little thing really what's destroyed my gardens?

Naysen,

Thanks for the info on copper sprays. I followed your link to the UC IPM website and poked around a bit. I found this interesting graph that lists the resistance potential of various fungicides (see the last graph column). It looks like resistance potential is only medium or low at best for any of our proposed sprays: http://www.ipm.ucdavis.edu/PMG/r783900911.html

I'm going to take your advice though and spray tomorrow morning early with the Green Cure. Then I'll try the copper after the GC has had a chance to work (or not).

Steve, I'm pruning about half my plants to a single stem this year, and they're showing signs of this also, of course to a lesser degree with fewer leaves. This year just seems especially bad for L.T. to me. Since I'm fairly close to the coast (~8 miles, with marine air coming in through Mission Valley/San Diego River) I've gotten used to seeing it every May/June, but never to this degree. That may be why you're seeing it for the first time in your area.

I'll let you both know how the spraying goes.
