Levels of soilborne diseases such as Sclerotinia blight, southern blight and pod rot were low in 2016.
Fungicide seed treatments increased stand establishment and yields by about 3,000 pounds per acre.
Early leaf spot was severe and control of early leaf spot resulted in yield responses of 1,000 to 1,500 pounds per acre.
Of the available high O/L peanut varieties, Lariat, Ole and Red River Runner were the most resistant to Sclerotinia blight, while Georgia 098 and Flavor Runner 458 were the most susceptible.
While disease pressure was low, the breeding lines A??SOK-V31, ARSOK-R35, and ARSOK-588-2 had low levels of Sclerotinia blight in both treated and untreated plots.
