I have just received a preliminary report of confirmed late blight infecting tomato plants in St. Mary’s County, Maryland. It is possible that plants from this greenhouse were planted in Charles County, Maryland. These two counties are in close proximity to Virginia and our growers near these locations (Eastern Shore, Northern Neck, Northern Virginia) should be proactive in making fungicide applications that target late blight on both potato and tomato. Fortunately, our prevailing weather conditions across the eastern part of the Commonwealth have been nonconducive for late blight development. As more details develop we will be able to more specifically give you recommendations. We will be sure to keep you up to date.
