GRAND FORKS, N.D. (AP) — North Dakota State University has now confirmed late blight on potatoes in four counties.

The disease lately has been confirmed in Pembina and Sargent counties. Earlier, it was found in Dickey County and Walsh County, the state's leading spud producer.

Late blight can hurt both yields and quality, and has the potential to grow rapidly out of control. The Northern Plains Potato Growers Association says farmers are urged to scout their fields and apply fungicides as needed.

So far, the disease has not been found across the Red River in Minnesota.
