Since sending out the Veg Crop Updates newsletter, I received several updates regarding new finds of potato late blight along the eastern seaboard – not yet posted to usablight.org. Late blight was detected in northeastern North Carolina and southern Virginia. The infected plant samples are currently being typed for pathogen clonal lineage/strain by pathologists at Cornell University.
Wet weather can promote late blight when temperature conditions are favorable and the pathogen is present.
