Abstract: Background and Objective: Cassava (Manihot esculenta, Crantz) is one of the most important staple food crops in Togo after maize. Cassava mosaic disease (CMD) is transmitted either through infected cuttings or by whiteflies. This study was to evaluate the incidence of begomoviruses causing CMD in the country’s cassava fields and updating knowledge of these viruses could help to better manage CMD in Togo. Materials and Methods: An initial investigation of viruses which might account for these symptoms was carried out using symptomatic as well as asymptomatic samples collected during epidemiological surveys performed in 2015 (472 samples) and 2017 (300 samples). Virus identification was carried out using PCR. Results: The presence of two strains of cassava mosaic begomoviruses (CMBs): African cassava mosaic virus (ACMV) and East African cassava mosaic virus (EACMV). The CMB incidence was lower in 2017 (12.42%) than in 2015 (26.23%) and ACMV was the dominant CMB across the regions sampled. Conclusion: The results indicate that good cultural practices and introduction of resistant cultivars, together with continuous disease monitoring, are required to reduce the impact of CMD in Togo.
