help with tomato leave damage

Asked June 15, 2015, 12:34 PM EDT

Good afternoon, I am attaching a couple of photos from one of my potato plants. This one is a heirloom and has those suspicious markings on the leaves. I never had blight before and I am very concerned because I have 20 more plants. Could you please help me identify what is the problem? And suggest possible solutions? Thank you very much in advance, Susana Mendez

This appears to be the first signs of early blight. Suggest removing the lower effected leaves and mulch under the plant with straw or grass clippings. http://extension.umd.edu/growit/early-blight-vegetables
