's governor has declared a state of emergency and ordered the release of $2 million to help agriculture officials fight a disease that has attacked citrus trees in the U.S. territory, AP reported. Alejandro Garcia Padilla said Tuesday that citrus greening has affected a large swath of the island's citrus crop, located primarily in the central region. Officials say the disease arrived in Puerto Rico in 2001 but was not discovered until 2009. The disease is spread by an insect and causes trees to produce green, disfigured and bitter fruits. Once a tree is infected, it dies in a couple years and cannot be saved. The disease has caused extensive damage in Florida as well.
