Late blight has been found at several locations in our reporting area this past week:

From Meg McGrath 6/23:

Late Blight on LI in Potatoes: Sample just came in and will soon be on its way to Bill Fry. Lots of sporulation. Field had been sprayed twice with Penncozeb: last Monday and about 10 days prior to that. One hot spot which grower is now taking out. Will be spraying with Curzate.

From Beth Gugino and Sara May 6/18:

Today in the Penn State Plant Disease Clinic, Sara May confirmed late blight on a tomato sample and potato sample both sent from the same home garden in Bedford County, PA. Sara is currently attempting to contact the home gardener and will ask them to destroy both crops. Late blight is also suspected on potato in Lehigh Co. A sample is being sent to the clinic for confirmation tomorrow.
