Pumpkins are grown on 5,000 acres in Indiana with an average yield of 6.75 tons per acre. Successful pumpkin production requires the use of varieties that yield well and produce pumpkins of the size, shape, color, and quality demanded by the market. Genetic resistance to the fungal disease powdery mildew is present in some varieties. This trial was designed to evaluate performance of pumpkin varieties in northern Indiana with and without treatment for powdery mildew. The trial included fourteen orange jack-o-lantern size pumpkins, one small or 'pie' pumpkin and one specialty yellow pumpkin.
