Citrus Greening May Plague California

Citrus greening disease, also called Huanglongbing (HLB), has been found in Los Angeles country. Greening has been impacting Florida for nearly ten years and has slashed commercial production of oranges by around 70%. The citrus disease was first identified in China and then moved to Brazil and the United States. It has been found in Florida, Texas, and now California.  About 2,300 infected trees have already been identified and destroyed in Southern California. The most effective pesticides to date including clothianidin belong to the neonicotinoid family, but these may reduce pollinator populations. The latest development to stop greening is a peptide that may be injected into trees and act as a sort of antibiotic.
