Asian Citrus Psyllid Webinar for Backyard Gardeners

We hope by now most people have heard about and are aware of the Asian citrus psyllid (ACP), a small brown insect that carries a deadly citrus disease called huanglongbing (HLB), threatening all backyard citrus trees as well as the statewide citrus industry.

This insect feeds on newly developed leaves of all varieties of citrus trees and can spread the bacteria that causes HLB. The HLB disease can kill a citrus tree in as little as 5 years and there is so far no cure or remedy.

Learn more about ACP and HLB by joining the free UC Ag Experts Talk on December 5 from 3:00pm to 4:30pm. Dr. Elizabeth Grafton-Cardwell, Director of Lindcove REC and Research Entomologist at UC Riverside, will address monitoring for these insects and the disease, as well as what Californian residents and backyard gardeners can do if they're in an HLB-infected area.

For PCAs and commercial growers, a separate webinar will take place on December 4, from 3:00pm to 4:30pm. Register here for the PCA and commercial grower webinar.

Additional information about ACP and HLB can be found in our Pest Notes: Asian Citrus Psyllid and Huanglongbing Disease.
