Field experiments were conducted to determine efficacy of a 99% mineral oil emulsifiable concentrate （EC） in controlling pumpkin powdery mildew. The 99% mineral oil EC at 2075 and 1411 mg/L controlled pumpkin powdery mildew 69.1 and 65%, respectively, significantly exceeding control provided by a comparison treatment of triadimefon 20% EC at 500 mg/L.
