Evaluation of Pumpkin Cultivars with Resistance to Powdery Mildew

Abstract

<p>Powdery mildew of cucurbits (melons, squash, pumpkins, etc.) is an annual problem in Iowa and in some years has the potential to ruin the crop if not controlled. Fortunately, the growing availability of powdery mildew–resistant cultivars now offers producers a more efficient approach to managing this disease and providing high-quality pumpkins for market. This trial was established to provide an unbiased performance evaluation of cultivars with reported resistance/tolerance to powdery mildew and to generate information helpful to growers for selecting cultivars best suited to their marketing objectives.</p>
