Thrips-vectored Tomato spotted wilt virus is a major production problem for tomato and pepper growers in Georgia. Management of this problem requires a true integrated approach. One of the more consistent management tools for reduction of spotted wilt has been the use of reflective mulch; however, this mulch has some negative horticultural characteristics for spring production, which has led growers to look for alternative approaches. One approach that has found limited acceptance, with little or no experimental evaluation, is the use of reflective streamers tied to the trellising stakes, with use of the standard black plastic mulch and susceptible varieties. We report on the results of experimental trials and field evaluations of these reflective streamers effects on thrips populations and incidence of tomato spotted wilt.
