Abstract
Field experiments were conducted at Tifton, Georgia from 2019 to 2020 to compare the effects of new peanut (Arachis hypogaea L.) cultivar ‘Georgia-16HO’ with the former industry standard cultivar ‘Florunner’, and in-furrow applications of phorate or imidacloprid insecticides on severity of tomato spotted wilt (TSW) caused by Tomato spotted wilt virus (TSWV), resultant yield, and crop value. Incidence of TSW was much lower for Georgia-16HO than for Florunner in both years, with differences more obvious in 2019 when the virus pressure was higher. Yield was greater for Georgia-16HO than Florunner in both years with greater differences when disease pressure was higher. Across all treatments, adjusted crop value for Georgia-16HO was ~$1450 /ha greater than for Florunner in 2019 and ~$839 /ha greater in 2020.
