Late blight was found on a commercial potato field in Camden Co., NC this week. Confirmation was made today by Dr. Pat Phipps at the TAREC based upon samples from this field. This outbreak is close enough to be considered a threat to the SE Virginia and the Eastern Shore of Virginia. We will have more information in our potato report tomorrow, but, based upon this news growers should consider treating their potato and tomato fields with a preventative fungicide such as chlorothalonil. If you have any questions feel free to contact me.
