What Is This On My Tomatoes

Question

Some of my tomatoes have this on them.

Answer 1

Unfortunately, this is one of several Tomato Blights. There is only one real cure, and that is burning everything infected, including the ground. If you can catch is early enough in the year, treating with a fungicide can help. By the time that you see symptoms, though, it is too late.
