The battle against the Asian citrus psyllid has taken place primarily in California backyards – until recently. A rise in commercial citrus psyllid detections means that all industry members play an increasingly crucial role in preventing the spread of an insect that carries the devastating Huanglongbing disease. Farm labor contractors, crew bosses, harvesters and other field workers can take several precautions to ensure the psyllid doesn’t spread from one citrus grove to another.

The California Department of Food and Agriculture (CDFA) has been forced to expand the quarantine area in Tulare County after the discovery of additional Asian citrus psyllids in the region.  The Grower reports, that as a result, a new 110-mile quarantine area exists, adjacent to Tulare’s existing quarantine area.  Although not yet defined or announced, CDFA is expected to further expand the quarantine area due to the detection of a single psyllid trapped outside the current and newly-announced quarantine areas.

The United States Department of Agriculture (USDA) announced that $1.5 million in funding will be made available to expand bio-control efforts to fight Huanglongbing (HLB), also known as citrus greening.  Agriculture Secretary Vilsack created a Huanglongbing multi-agency coordination group (HLB MAC Group) in December.  This is the first funding for these efforts made available by the group.   The HLB MAC Group serves to coordinate and prioritize Federal research with industry's efforts to complement and fill research gaps, reduce unnecessary duplication, speed progress, and more quickly provide practical tools for citrus growers to use.  It also fosters greater coordination among federal and state agencies in responding to citrus greening.
