This morning I got a call from a grower who has very suspicious tomato plants. I also just received the alert below from Mark Hutton, Vegetable Specialist with UMO Extension. It is time to raise the level of concern.
Please be aware late blight has been confirmed in Warren. The warm damp weather is conducive to the spread of this disease. Please scout your tomatoes and potatoes for signs of the disease and consider applying fungicides. For more information on late blight please see “Tomato and Potato Late Blight Information for the Upcoming Growing Season” at http://umaine.edu/publications/2427e/.
