What are the black spots on my tomato leaves?
I was wondering what the black spots on tomato plant leaves were?

Several fungal diseases can cause black spots on tomato leaves. Septoria leaf spot, alternaria leaf blight, early blight, and late blight all cause leaf spotting. You can use a protective fungicide spray to prevent the leaf spotting if you wish.
