Help, Tomato Blight

[Prostetnic Vogon Jeltz]

A blight is spreading through my tomato plants,

someone identify this. Is there anything I can do?

It looks to me (based on the single photo) like one of the leaf spots, like bacterial spot or septoria spot. Remove the badly infested leaves and use a copper spray on the plants. I'd also suggest using a kelp (such as Maxicrop) in your foliar spray. The extra potassium and micronutrients would be valuable. (I'm looking at the illustrations in _Identifying Diseases of Vegetables_ published by Penn State.)

Try looking at the photos here and see what you think:

please, no poetry!)
