The strange weather this year was a "perfect storm" for Late Blight.
Quoting:the microscopic spores of P. infestans develop on leaves and stems when temperatures are above 50 °F and humidity stays at 75% for more than two days. The spores of the fungus develop rapidly in wet and cool weather.
We had more wet and cool weather this year (add in April and May) than I can remember. Given how far LB can travel on the wind, I am amazed I didn't manage to get any. I had a nice (my first ever) crop of tomatoes, too!
I am glad to read about late blight, too. I read the New York Times article but it didn't provide pictures and I was very curious to see what it looked like. Our weather is dry so we probably don't get it as often as those of you back east, but we do get various fungal diseases and late blight may be one of them. Now I can check the DG archives if anything I grow gets something that looks like it.
Yes, I heard of LB in my neighborhood, but thankfully, I was spared, and my first ever crop of tomatoes are starting to come fast and furious. I was terrified all spring, and read every scrap of information!
