Cultivars with increased field resistance to TSWV still responded to insecticide treatments, row patterns, tillage conditions, and planting date alterations. The results reiterate that the newer cultivars are compatible with all the available risk reduction factors prescribed in the peanut Rx. Integrating these newer cultivars could be still advantageous: 
They would allow the transition from using broad-spectrum insecticides such as Temik and Thimet to less toxic insecticides without compromising yields. 
Newer cultivars still respond to integration with various cultural tactics (row patterns and tillage), as well as planting date alterations. Despite a substantially low spotted wilt year, such differences were realized. These differences would be even more visible under a severe spotted wilt year more readily. Therefore, combination of these newer cultivars with increased field resistance is very vital to maintaining sustainability in peanut production and increasing profitability to GA Peanut Farmers.
