Tomato spotted wilt virus (TSWV) is an important pathogen that causes disease in numerous crops, especially tomatoes and peppers. Resistance-breaking variants of TSWV were discovered in NC on tomato varieties with the Sw-5 resistance gene during the summer of 2022. Given that host resistance is currently the most effective management strategy of TSWV, these strains pose a great threat to tomato production in the coming years. This article will focus on TSWV identification and management strategies for tomatoes and peppers.
