Developing/Validating a Weather-Based Decision Support System for the Management of White Mold (sclerotium rolfsii) in Peanut

Field studies were conducted in 2014 to assess the value of the model in determining early season applications of fungicides for S. rolfsii control. In these studies, it was observed that the model performed as well or numerically better than the calendar based sprays in all but 5 treatments for both Proline and tebuconazole products. The mixing of diseases, especially leaf spot diseases, in the plots makes it difficult to assess the true effect of these fungicides on white mold development. However, the indication that early planted peanuts have a higher probability of seeing significant white mold hits could be useful in assessing the value of the model, as it utility will vary depending on planting date.
