I usually check my garden every day but missed yesterday. Went this afternoon and found my a potato plant looking like this:

Leaf blight? Black_10

thinking Is it a blight? Bug? Bad soil? And most important . . . can the crop be saved? We've had a cold snap the past few days

Here is a good resource for this kind of diagnostics http://extension.umass.edu/vegetable/diseases/tomato-septoria-alternaria
UCornell has one too. http://vegetablemdonline.ppath.cornell.edu/DiagnosticKeys/TomLeaf/TomLeafKey.html

I looked under tomato because they get more pictures. I think it looks like early blight or septoria but maybe not.... Don't over water and pick off bottom leaves and see if it can out live it. But then DO NOT grow tomatoes in that area at all for a long time. Or any of the solanacae family. Do not put the leaves into the compost.

I know I have seen it in my potato plots and got plenty of tubers anyways. But clean up and strict rotation becomes very important.

Are there any spots on the stems? Yes it does look like early blight, but it could be something else. Remove the effected leaves and trash or burn them. Contact your County Extension Service Ag Agent if you need a positive ID and treatment recommendations.
