I have every type of spot on my tomatoes this year - except late blight, thank goodness. Big spots, small ones, orange and brown and black. The damage is pretty much limited to the fruits and is not on the leaves or stems of the plants.
Its been perfect weather for fungi this summer - hot and humid. But I think much of my problem is that I planted my tomato plants too dense and between tall popcorn and sunflowers that reduce airflow. Other gardeners in our community garden have nice tomatoes that they planted with lot of airflow. Next year I will do this too....
