Abstract

Tomato spotted wilt caused by Tomato spotted wilt virus (TSWV) continues to be a serious disease problem on tobacco (Nicotiana tabacum L.), peanut (Arachis hypogaea L.), tomato (Lycopersicon esculentum Mill.), and pepper (Capsicum annum L.) in the southeastern United States. Impatiens necrotic spot virus (INSV, formerly known as TSWV-I) is an emerging virus found mostly in greenhouse production of ornamentals and is also vectored by thrips. A few years ago INSV was detected in peanut in Georgia and Texas and its occurrence appears to be increasing). Mixed infections of TSWV and INSV in tobacco have been observed within the last two years in North Carolina and Kentucky. Our objective was to sample several locations in Georgia, Florida, South Carolina and Virginia to confirm and report the presence of natural TSWV and INSV mixed infections in tobacco.
