Stay Vigilant with Asian Citrus Psyllid Finds on the Rise

In the past few months, we have seen sporadic Asian citrus psyllid (ACP) detections popping up across California. While the citrus industry’s efforts have thus far kept Huanglongbing (HLB) out of commercial groves, these recent ACP detections are a reminder that we cannot let our guard down. The most effective way to prevent the spread of HLB is to keep …

Root Bacteria Could Help Defeat Fatal Citrus Disease

A UC Riverside-led team is looking at tiny underground microorganisms for a way to prevent a huge problem — Huanglongbing, a disease with no cure that has decimated citrus orchards worldwide.

New Targets for Huanglongbing Treatments

Scientists are closer to gaining the upper hand on a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable.

Barking Up the Right Tree: Canines Detect HLB

In September 2019, huanglongbing—also known as HLB or citrus greening—was detected in residential citrus trees located in Ventura County, in southern California (and just recently, the first HLB carrying Asian Citrus Psyllid was detected in a commercial CA citrus grove). The disease, which has no known cure, is caused by a bacterium that devastates citrus plants and is transmitted by …
