Late blight genotype US-24 has been characterized from a potato field in Adams Co. This field is just over the county line from Waushara. 24 is resistant to mefenoxam (Ridomil). The presence of both 23 and 24 in the region suggests multiple potential sources and the need for further sampling/testing.
