The late blight confirmation is the first reported in the North East this season. The find is close enough that potato and tomato growers in Ontario should be on alert for this disease. Scout your fields regularly and remove any cull piles and volunteers from your farm. Tomato growers can refer to this handy post on late blight and look-alikes : Tomato Late Blight Look-Alikes
