I'm glad I decided to finally look into this thread, after all these years. Now I know what my tomato plants I had to yank out had! The pics verified it, and the description of how it starts at the top, etc. I never saw this disease till this year, but it is also the first year I noticed a thrip-like bug lurking around. Didn't give it another thought. Now I know, once again thanks to this forum.
