Powdery mildew of sugarbeet, caused by Erysiphe polygoni, was first found in California in 1934, but did not become prevalent statewide until the 1974 season. Results of trials in 1974 indicated sulfur dust (40 pounds per acre) or wettable sulfur provided excellent control of sugarbeet powdery mildew. ‘Trials were initiated in 1975 to compare 20 pounds of sulfur dust per acre, wet-table sulfur, Benlate + oil, and various other combinations.
