Blight affecting tomatoes and potatoes


UPDATE August 5, 2009: The Wisconsin Department of Agriculture, Trade & Consumer Protection confirms that late blight on tomato has appeared in Dane and Rock counties, the first cases of the disease in the state in six years. Full article: LATE BLIGHT ALERT

Gardeners are being warned to destroy any Solanaceae plants (tomato, potato, eggplant) suspected of suffering from "late blight" disease, especially those purchased from big box stores.

The disease, associated with the Irish Potato Famine of the 1840's, is caused by the Phytophthora infestans fungus. While not harmful to humans, it is extremely contagious and deadly to plants.
