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.

Late blight discovered in SW Michigan

A late blight outbreak was reported and has been confirmed in St. Joseph county. So far a single outbreak has been confirmed in a field near Sturgis. With the thunder storms and heavy rains that have swept across the state in recent days it is important to be extra vigilant when scouting fields for late blight. Particular attention should be paid to pivot tracks and other such lanes created by farm machinery. For further information on measures that should be taken when late blight is observed refer to the Late Blight extension bulletin. This bulletin is also available as a high quality downloadable .pdf file.
