Pumpkins for decorative use are grown on more than 4,000 acres in Indiana. Combined acreage in Indiana, Michigan, Illinois, and Ohio represents about a quarter of pumpkins grown for decorative use in the United States. Successful pumpkin production requires the use of cultivars 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 eight jack-o-lantern size pumpkins, one small or pie pumpkin, and three mini-pumpkins. Also reported are yield and fruit characteristics for 17 additional varieties grown in unreplicated plots.
