In follow up from yesterday, the tomato late blight sample from Monroe County has US 23 clonal lineage of Phytophthora infestans. This is same type identified in our previous samples from WI in 2019.

Late blight was also confirmed in potato in central Waushara County today. We will determine clonal lineage and follow up yet this week.
