 An Interactive Website for Asian Citrus Psyllid Management


Commercial Citrus – How will the citrus grower manage the pest and disease?

The deadly huanglongbing is spreading within California residential areas and threatens commercial citrus production.  This web site is designed to show citrus growers where the Asian citrus psyllid and the HLB disease are located.  Since there is currently no cure for the disease, the best management strategy is reducing the psyllid vector with insecticides and removal of infected trees.  This web site will provide a list of the ACP-effective insecticides, information about the best timing of their use, and strategies for treatment. 


Residential Citrus – What should I do to protect the citrus in my yard?

There is currently no cure for the huanglongbing (HLB) disease that kills citrus trees and is spread by an insect, the Asian citrus psyllid.  It is estimated that 60% of Californians have at least one citrus tree in their yard and so HLB is going to have a devastating effect on the California residential landscape.  Currently the only way to control the disease is to reduce the psyllid that spreads it and to remove trees that are infected or located near the infected trees.  This website will provide you with information about how near the insect and disease are to your home and what you can do to help protect your trees.
