The genuses Citrus are commercially important fruit crop belongs to Rue family. They are mainly cultivated in the subtropical and tropical regions of the world between 400 north and south latitude in over 137 countries. However, citrus production has been delayed with biotic and a biotic factors. Mainly, plant viruses are highly prevalent and serious threat to cultivated plants and agricultural production in plants like vegetables and fruits worldwide. Citrus triteza virus (CTV), is the largest and most complex member of the genus Closter virus (family Closteroviridae) that induce the most destructive disease of cultivars and hybrids of citrus worldwide. The only natural non-citrus host that has been reported is Passilora. Natural hosts of CTV remain essentially symptomless when infected by most CTV isolates. To establish a productive infection in a host plant virus needs to be able to move throughout the plant from an initially infected cell. The spatial and temporal spread of CTV in citrus orchards has been studied in different parts of the world. The most common diagnostic symptoms of CTV include Quick Decline, Seedling Yellows and Stem Pitting Disease. The diseaes is economically most important constraints of Citrus production widely, little emphasisahs been given especially in Ethiopia. Exclusion and Quarantine, Resistant/tolerant rootstocks and Vector control are the most common means of CTV management today. Therefore, if we need to use citrus as one income source for the country, future research should give great focus on those viral diseases Like CTV as of other economical diseases as a whole.
