'Tomato spotted wilt virus' (family 'Bunyaviridae', genus 'Tospovirus') is an important virus infecting horticultural crops and is transmitted solely by thrips species. The virus infects a wide range of plant species and presence of 'Frankliniella occidentalis', reported to be the most efficient vector species has complicated its management. TSWV was first reported in Kenya in 1999, causing serious yield losses in tomato production, and has continued to cause sporadic yield losses. This study was undertaken to determine the distribution and genetic diversity of the virus a decade after its incursion into Kenya. The study further evaluated important factors in the epidemiology of the disease and its management. |
