Importance
CTV is the most economically important and damaging virus of citrus trees. It can be spread quickly and do damage not only by killing trees with sour orange rootstock, but also by stem pitting normal citrus trees. It has killed more than 80 million trees worldwide, mainly in South Africa since 1910, Argentina (10 million) and Brazil (6 million) since 1970, and the U.S. (3 million) since 1950. With the spreading of T. citricida the severity and impact has increased dramatically in Central America and the U.S. In Spain there has been a progressive decline in production from over 40 million sweet orange and mandarin trees.

—Marianne E. Neifert (20th century)
