The World’s MOST WANTED BUG! Have you seen the Asian Citrus Psyllid?

Posted by GeriMiller on 21 Apr 2012. Filed under  Garden Care, Plant Diseases, Plant Resources, Uncategorized View Comments

You may remember hearing that the Asian Citrus Pysllid was found recently in Hacienda Heights (suburb of the San Gabriel Valley in LA County) generating renewed concern about the possible spread of the devastating and incurable citrus disease, Huanglongbing or Citrus Greening Disease which could desecrate our 1.2 BILLION dollar citrus industry in California as it has in Florida. First arriving in the U.S. in Florida in 1998 (not detected until 2005), Huanglongbing originated in Asia and identified in China as early as 1919. The history of this disease is long and its effect devastating.
