At least two common tomato problems are referred to as tomato blight and another one is often thrown into the same mix: early blight, late blight, and Septoria leaf spot.
They’re each caused by different funguses. You can tell these three problems apart by what they look like, what parts of the tomato they affect, and when their symptoms appear. But the good news is this: all three can be treated and controlled similarly with biofungicides or fungicides and by practicing good preventative care.
