The California Citrus Pest and Disease Prevention Committee was created to advise the California Secretary of Agriculture and the agricultural industry about efforts to combat serious pests and diseases that could threaten our state’s citrus industry. The committee was authorized through Assembly Bill No. 281 (AB 281), which was signed into law on October 9, 2009.   The bill sets out the powers and duties of the committee giving it the authority to develop a statewide citrus pest and disease work plan, subject to the approval of the Secretary.  Key responsibilities are:
  • Develop informational programs to educate and train residential owners of citrus fruit, local communities, groups and individuals on the prevention/detection of pests, diseases and their vectors specific to citrus.
  • Develop programs for surveying, detecting, analyzing, and treating citrus pests and diseases.
  • Set box assessment to help pay for citrus pest & disease detection, treatment and Educational outreach programs.

CPDPC CDFA Treatment Prog

CPDPC CDFA Detection & Treatment Program

There are two different programs:  one for industry and the other for residential and public settings.


CPDPC funds a statewide commercial citrus trapping program which is administered by the Citrus Research Board.  For more information, see Field Ops and Lab.

Residential/Public Settings:

This program is administered by the California Department of Food & Agriculture (CDFA) and consists of three main parts:

1. Survey & Detection:

The California Department of Food and Agriculture (CDFA) maintains a cooperative state/county trapping program in various southern California counties for ACP to provide early detection of any infestation in the county.  Traps are serviced by agricultural inspectors.  The trap used for ACP detection is the yellow panel trap.  The yellow panel trap is a yellow two-sided board coated with stickum.  ACP are caught on the sticky capture surface.  Yellow panel traps have proven successful at detecting infestations of ACP.  Proper deployment enhances catch success.

At all locations where traps are placed, the host plant is visually inspected for ACP.  If there is evidence that ACP exists, the host will be sweep netted for ACP samples.

Any detection of ACP not associated with a recently arrived nursery or landscaping shipment from an infested area shall trigger a delimitation survey.  This survey shall continue for three life cycles past the last psyllid found.

All properties within 100 meters of the initial detection shall be surveyed.  Initial surveys should be door-to-door, moving outward in all directions from the original detection site.  Additional detection locations shall be used as new epicenters to expand survey boundaries using a ¼ mile radius.  Survey will be repeated every two weeks. If high or scattered ACP populations are found in the initial inspections, a transect survey may be implemented to rapidly determine the extent of the infestation.  This involves inspecting a minimum of 10 properties per square mile.

2. CDFA Treatment:

Trigger:  Treatment is warranted on the detection of one or more psyllids.

Treatment Area: The typical treatment area is 400 meters around any ACP detection site. Treatment areas may extend up to 800 meters based upon the following criteria: The detection of additional ACP or immature life stages detected within the survey area; the availability of host plants in the region, the presence of huanglongbing (HLB) disease within the pest population or host plants; and the availability of State resources. Only host plants are treated.

Treatment Options:  Both foliar and systemic insecticides will be applied. Foliar insecticides are useful for immediate reduction of the adult population in order to eliminate dispersal, while systemic insecticides are necessary to kill the sedentary nymphs.  The frequency of the treatments is dependent on the insecticide applied and severity of the infestation.

3. CDFA Outreach:

Informational materials will be made available to the public.  These may include mass mailing of postcards, distribution of posters to businesses, pamphlets distributed by survey staff, development of a website linked to the CDFA website, additions to preexisting informational kiosks, incorporation of information into classroom teachings, etc.

Residents of affected properties will be invited to a public meeting where officials from various agencies (California Department of Pesticide Regulation, Office of Environmental Health Hazard Assessment and the County Agricultural Commissioner) are present to address residents’ questions and concerns.  Residents are notified in writing at least 24 hours prior to the scheduled treatment.  Following the treatment, completion notices are left with the residents detailing precautions to take and post-harvest intervals applicable to any citrus fruit on the property.

A toll-free hotline will be staffed to answer questions related to this project.  This telephone number is provided on all treatment notifications.
