Southern California ACP/HLB Update - Sandra Zwaal & Cressida Silvers

UPDATE IN VENTURA CO
”As of December 15, a total of 67 trees and 5 ACP samples in Ventura County have
been confirmed positive for CLas, the bacterium that causes HLB. All detections
are in residential areas of Santa Paula. CDFA crews are working to complete
treatment and removal of the infected trees. CDFA is also conducting mandatory
surveys and ACP treatments of all citrus within 250m of the tree detections.
Currently there is no commercial citrus in the 250m delimitation areas. In
response to these detections, a 5-mile HLB quarantine is in place around the
Santa Paula find sites, affecting commercial citrus in the area ”







UPDATE IN SAN DIEGO CO

“A newly established HLB quarantine in San Diego Co. has been declared following
the detection of the deadly citrus plant disease Huanglongbing (HLB) in five
trees located on a residential property with non-commercial citrus acreage in
the Valley Center area of San Diego County. As of November 17, 2023, a total
of 211 residential citrus trees have been confirmed positive for HLB in
Riverside Co. for a total of 6,790 residential citrus trees statewide. New HLB
tree detections continue to be found in the city of Corona.”












Updates to HLB Bulk Citrus Quarantine Requirements



Effective November 22, 2023, the Citrus Pest and Disease Prevention
Division(CPDPD) is updating the requirements for moving bulk citrus fruit within
and from a huanglongbing (HLB) quarantine area to a packer/processor. More
complete information regarding the mitigations required for fruit movement may
be found on the Citrus Grower/Grove Manager Information page:
https://phpps.cdfa.ca.gov/PE/InteriorExclusion/pdf/acpgrowerinformation.pdf







Listed below is a summary of the updated requirements:




A. Movement within a contiguous HLB quarantine:

No mitigation required*  (previously required: 1 mitigation)




B. Movement between non-contiguous HLB quarantines:

1 mitigation required(previously required: 2 mitigations or a wet wash)




C. Movement from an HLB quarantine but within the same county:

1 mitigation(previously required: 2 mitigations or a wet wash)

*1 mitigation may be required dependent on origin and destination counties. See
the Citrus Grower/Grove Manager Information page for details.




The CPDPD will be signing revised compliance agreements with growers within an
HLB quarantine, as well as packers/processors receiving fruit from a quarantined
area.




HLB Quarantine and Treatment Area



Kern Update ACP Update - Judy Zaninovich

“There have been NO new ACP detections in Kern County since my last update.

To date in 2023, there have been 5 ACP detections - four were residential
detections and in commercial citrus west of Arvin.

To aid in the suppression of ACP in Kern County, CDFA is continuing to make
monthly releases of the parasite, Tamarixia radiata, in residential areas which
have had past ACP detections.”



Tulare County ACP Update - Jessica Leslie

“There has been ONE new ACP detection in Tulare County since my last update. A
single adult psyllid was found on a trap North of Lindsay. It was deemed a
regulatory event and CDFA did not find any other activity on the surrounding
residences or in the nearest commercial citrus groves. The San Joaquin Valley
taskforce is asking for any growers within an 800M range of the detection to
treat their groves in order to protect themselves and stop any possible ACP
movement. The growers in the treatment range have been contacted. There was
another singular ACP find in Tagus back in June, the growers in the area that
requires treatment have cooperated and there have not been any finds since.”



— Fresno Update —

- There has been 1 new ACP finds since the last update. This is the 2nd find of
the year for the Fresno region. This time again, there is NO commercial citrus
within the immediate vicinity.



— Madera Update —

There have been no detections in 2023, the last detection was in December 2022.

For quarantine regulation questions, please call the CDFA ACP Program Office
(559) 625-1040 or the Fresno County Agricultural Commissioner's Office (559)
600-7510 or the Madera County Agricultural Commissioner’s Office (559) 675-7876.




STAY VIGILANT!!  The best way to make sure the San Joaquin Valley is not
impacted by HLB is to keep ACP suppressed down to the lowest level possible.
Using Best Management Practices such as making sure all equipment arriving and
leaving the ranch is free from citrus stems and leaves, growers can greatly help
to keep ACP from establishing in their citrus orchards. And, using ACP-effective
materials when treating for other pests along with thorough treatment on the
borders of the block will also assist in suppressing any un-detected
populations. Click on the button below for the University of California's list
of ACP-effective materials.
