Dread Citrus Disease Turns Up in California, Texas

摘要

When the worst disease of citrus plants was detected in Florida in 2005, growers and researchers elsewhere in the country watched with trepidation. Citrus greening, also known as huanglongbing, turns fruit sour and kills trees within a few years. There is no cure. Transmitted by a tiny insect, the bacterial disease rapidly conquered Florida, doubling the cost of citrus production and raising questions about the future of the industry. Fred Gmitter of the University of Florida says, "The dilemma for Florida is: Where do we go from here."
