San Gabriel Valley Sprayed for Citrus Killer

An invasive and deadly disease that attacks citrus trees was found in Hacienda Heights March 30, and now no fruits are allowed in or out of a 93-square-mile quarantine area for the next two years. This week, state agriculture workers are going door to door to spray trees in the Los Angeles suburb. Trees infected by Huanglongbing, or yellow dragon disease, will have to be removed. The disease is carried by the Asian citrus psyllid, a small flying insect. NBC4’s John Cadiz Klemack reports from Hacienda Heights.
