Stadium Fungicide

For the best possible yield and quality, growers should utilize an integrated full-season approach from seed through storage. The yield and quality that result from good growing practices must be protected with good storage practices to preserve potato quality. Fusarium dry rot is one of the most important post-harvest diseases of potato. Soil-borne Fusarium infects tubers at harvest through wounds and can be present in the soil for many years. Silver scurf causes damage to the potato skin and results in higher water/weight loss during storage. Damaged skin may result in higher waste in removing the skin during processing.

Stadium fungicide combines three active ingredients—fludioxonil, azoxystrobin and difenoconazole—to provide targeted disease control for potatoes. Each active ingredient in Stadium has a different mode of action, which is highly effective for managing the spread of silver scurf and Fusarium dry rot during storage. Stadium remains active for months of storage, providing long-lasting protection with only one application.
