Abstract
Potato (Solanum tuberosum) is the third most important crop worldwide in terms of consumption after rice and wheat. The vegetative propagation and the global trade of seed potatoes along with the significant impact of potato viruses on potato crops have imposed many potato viruses as universal challenges to potato production worldwide. In many countries, the great efforts to study potato viruses and develop effective management programs, including certification schemes, have been rewarding. However, the lack of effective control of potato viruses has minimized the profit margin of potato production in most potato-producing areas. In the current chapter, we summarize major potato viruses of a global significance to potato production focusing on the epidemiology, detection, and possible management practices. This chapter does not replace previous reviews on potato virus diseases available, but we intended to provide a thorough review of applied knowledge relevant to potato growers and researchers involved in management programs of potato virus diseases.
