Abstract

Release of peanut cultivars with enhanced tomato spotted wilt (TSW) resistance along with the decline in the incidence of this disease gives Alabama producers the option of earlier planting of irrigated peanuts to optimize farm operations and lower seeding rates to reduce input costs. Mid-April and mid-May plantings of the cvs. Florida-07, Georgia-06G, and Georgia Green at 6.6, 9.8, 13.1, and 19.7 seed/m were monitored over three years for TSW, stem rot, and leaf spot diseases as well as yield. Despite low TSW pressure and lack of a seeding rate response, disease incidence was higher in Georgia Green than Florida-07 and Georgia-06G with higher TSW indices noted for the April than May plantings of the former but not latter two cultivars. While not impacted by planting date, stem rot incidence, which was higher at 13.1 and 19.7 than 6.6 seed/m, was lower on Florida-07 than Georgia-06G and Georgia Green with the latter proving most susceptible. Although leaf spot intensity was not impacted by seeding rate, disease ratings were higher for May than April plantings, with Florida-07 and Georgia-06G having lower leaf spot ratings than Georgia Green in two of three study years. While planting date did not impact yield in two of three years, higher yields were recorded at 13.1 and 19.7 than 6.6 seed/m, with Florida-07 and Georgia-06G having higher yields than Georgia Green. Accepted for publication 16 February 2015. Published 20 April 2015.
