Prevalence of potato viruses on potato (Solanum tuberosum L.) grown in the Western Highlands of Cameroon

Abstract Solanum tuberosum L. is considered by the Food and Agricultural Organization as one of the alternative food crops that can help to fight against hunger in the world. However, this crop species is subject to numerous attacks, among which viruses are responsible for causing considerable losses of crop quality and yield. The objective of this study was to detect Potato virus X (PVX), Potato virus Y (PVY) and Potato leaf roll virus (PLRV) and to determine the prevalence of these viruses in potato farms in the Western Highlands of Cameroon.
