Late Blight found on Tomato in Gratiot county

Today (July 29, 2009) the plant disease diagnostic center at MSU received a tomato plant that had late blight on both the fruit and foliage. This sample was from a home gardener in Gratiot county. There has been a severe outbreak of late blight on tomatoes in the Northeast, in states including New York. Potato growers in Gratiot county should be on alert as in the Hudson Valley region of New York, the disease has jumped from tomatoes to potatoes and is wreaking havoc in both. The source of the outbreak in the Northeast is being investigated by pathologists and it is thought that home gardens likely helped spread the infection: Lowe's, Home Depot, Kmart and Wal-Mart all sold tomato seedlings with late blight in their garden centers from April to June. As such this find in Gratiot county may also be from a similar source. The New York Times has published several articles on the subject. Click here and here for more information.
