Abstract
Insecticides that target thrips vectors have failed to provide adequate control of tomato spotted wilt virus (TSWV) in peanuts in the southern United States.
In recent years, research has been conducted to determine how the incidence of this disease is influenced by cultural practices.
This paper reviews that research.
Cultivar selection, planting date, plant population, row pattern, and irrigation level influence the incidence of TSWV. Of these, cultivar selection has the greatest and most consistent effect.
The use of specific planting dates is also an effective management practice.
Other studies suggest that volunteer peanuts may play an important role as fall and spring reservoirs for TSWV, and reduction of volunteers may be an important component of an integrated disease-management program.
Tillage systems affect populations of thrips vectors on peanuts, but no information is available on the influence of tillage on the incidence of TSWV. Cultural practices will play an important role in integrated programs to manage TSWV. There is a need to know how the incidence and severity of TSWV vary in peanut production systems that use different combinations of cultural practices.
