tomato disease question

Asked July 29, 2015, 1:47 PM EDT

how do you tell the difference between Septoria Leaf Spot (a fungus) and Bacterial spot. I realize for both some of the things you can do to help are the same like removing infected leaves, mulching, etc. but if it's Septoria Leaf Spot you can spray a fungicide and hope it doesn't get worse. So how do you know the difference?

It can be hard to differentiate between some of these diseases.
Here are some links - with photos and descriptions - that should make it a little easier. Control methods are included:
