No spores of Phytophthora infestans (late blight) were detected at any site this week. With the hot dry weather in place across the region the risk of late blight remains low for Southern Idaho.

Spores of Alternaria solani (early blight) were observed on three days at Acequia. Spores of Sclerotinia sclerotium (white mold) were observed at Parma, American Falls, Kimberly, Golden Valley, Acequia, Paul, Aberdeen, Blackfoot, Idaho Falls and Rexburg.
