Learn to Scout ACP


UC to conduct ACP scouting workshops

Registration is now open for Asian citrus psyllid scouting workshops to be conducted in Fillmore and Moorpark on July 13. Intended for grove owners, managers or farm employees, the sessions will provide instruction in ACP population monitoring as a way of improving the area-wide management (AWM) strategy in Ventura County.


At each workshop, University of California research entomologist Beth Grafton-Cardwell will provide an overview of proper scouting techniques, which participants will have the opportunity to practice in blocks of trees known to host ACP. Participants are asked to bring a hand lens (a loaner hand lens will be provided if you do not have one).


The workshops are free, but participation in each is limited to 25 people and advance online registration is required. 


Session 1

10 a.m. to noon in Fillmore. Register at


Session 2

1:30 to 3:30 p.m. in Moorpark. Register at


Registered participants will receive details about the physical location of each workshop by email 48 hours before the event.


Science For Citrus Health

Interested in the research addressing Huanglongbing (HLB) disease? Check out the University of California website with the latest information. The site also has fact sheets, Powerpoint slides, and pictures that can be used for general outreach and presentation.  


2018-2019 Area-wide treatments start soon for Ventura County

The next round of coordinated AWM treatments begin in mid-July, and reminders for the first ACP treatment window have been sent. If you did not receive a reminder, do not receive ACP email blasts, or need pest control/tree removal referrals, please contact your grower liaisons Sandra Zwaal and Cressida Silvers. Please remember to file Pesticide Use Reports (PURs) electronically and on a timely basis. Manually filed PURs can take months for recognition as an ACP treatment. For a no-cost CalAgPermits account to file electronically and for training, contact the Agricultural Commissioner's Office.

HLB Confirmations

As of June 29, the total number of trees confirmed as infected by HLB had risen to 676. None were found in commercial groves. The HLB quarantine boundaries and the latest tally of HLB confirmations, updated weekly, is available online at As confirmations increase and spread closer to commercial citrus, it is a good time to consider removing citrus trees not worth the resources required to protect them from ACP and HLB.  


Meetings and resources

The Citrus Pest and Disease Prevention Committee will meet July 11 in Visalia. Attendance is free.  Here is a link to the CDFA site with agenda, venue, and webinar information:
