Late blight is a fungal disease that has been rampant on the Eastern Seaboard this year due to the cool temperatures and moist conditions. The same blight that caused the irish potato famine, it affects tomatoes and potatoes and any other plants in that same plant family. Sadly, the disease wipes out plants quickly — even otherwise healthy plants — and the disease spores can ride the wind from neighboring plots. So if you do get late blight, you’re doing your entire neighborhood a favor by dealing with it quickly and appropriately.

I’m traveling to Johnny’s Selected Seeds on Thursday of this week and will gather any information I can about disease-resistant varieties.
