1 ACP.HLB PROGRAM UPDATE California Department of Food and Agriculture Protecting California s agricultural and natural resources against damage caused by exotic plant pests and diseases 1

2 BACKGROUND.OVERVIEW Following the detection of ACP in Tijuana, Mexico on June 23, 2008, the CDFA and the San Diego County Agricultural Commissioner s Office increased surveillance On September 2, 2008, the USDA confirmed a positive ACP in San Diego County, CA October 2008 ACP detected in Imperial County during a visual survey August 2009 ACP detected in Orange County on a yellow panel trap August 2009 ACP detected in Los Angeles County on a yellow panel trap October 2010 ACP detected in San Bernardino County on a yellow panel trap December 2010 ACP detected in Riverside County on a yellow panel 2 trap

4 OVERVIEW.CDFA s ROLE Detection Trapping and Visual Survey Yellow Panel Traps Visual and Sweep Net Survey Delimitation Trapping Treatment Quarantine Outreach 4

5 ACP.PROGRAM.FUNDING CDFA effort is funded through the USDA, citrus industry and State Emergency Funds Federal program budget is $11.5 million (CHRP) Citrus industry approved $7.6 million for treatment operations Emergency Fund Request for FY is $584,766 5

6 TRAPPING.SURVEY

7 CITRUS.COMMODITY.SURVEY % of the commercial citrus for ACP and HLB High risk urban areas (5 sites per square mile) Citrus production nurseries Nurseries that sell host plants Yellow Panel (YP) traps are placed at packing houses that receive bulk citrus YP traps are placed at high risk location (markets and airports that receive host plant material from ACP infested areas) 7

8 TRAPPING.SURVEY Total ACP Traps: 39,251* County Number of Traps County Number of Traps County Number of Traps County Number of Traps Alameda 188 Kings 438 Riverside 1926 Santa Clara 553 Butte 435 Los Angeles 6675 San Benito 91 Shasta 15 Contra Costa 41 Madera 863 San Bernardino 1627 Stanislaus 566 El Dorado 4 Mariposa 1 San Diego 3999 Sutter 45 Fresno 4201 Merced 570 San Luis Obispo 1085 Tulare 1822 Glenn 593 Monterey 353 San Joaquin 204 Ventura 4255 Imperial 4423 Orange 1752 San Mateo 122 Yolo 30 Kern 1381 Placer 60 Santa Barbara 813 Yuba 120 *Current Year Total 8

9 SURVEY.DETECTION Visual and Sweep Net Survey All properties within 100 meters of the initial detection Door-to-door, moving outward in all directions If high or scattered ACP populations are found, a transect survey may be implemented to rapidly determine the extent of the infestation 9

10 SURVEY.DETECTION Branches and leaves are brushed and examined for ACP life stages before they are bagged and transported to CDFA s lab in Meadowview, near Sacramento More than 15,000 plant samples and more than 6,000 psyllid life stages have been tested so far, with none testing positive for HLB-associated pathogens 10

11 ACP.QUARANTINE.AREAS Imperial County (the entire county) Los Angeles County (the entire county) Orange County (the entire county) Riverside County (portion) San Bernardino County (portion) San Diego County (portion) Santa Barbara County (portion) Ventura County (the entire county) 11

16 ACP.TREATMENT

17 TREATMENT.NOTIFICATION Proclamation of an Eradication Project (PEP) The PEP is a document that informs elected officials (Assembly, Senate, Mayor) and other government agencies (Agricultural Commissioner, school district, Fish and Game, OEHHA, DPR, USDA) of CDFA s plan to initiate a treatment program. 17

18 TREATMENT.NOTIFICATION Proclamation of an Eradication Project (PEP) continued OFFICIAL NOTICE PROCLAMATION OF AN ERADICATION PROJECT (PEP) 18

19 PUBLIC.MEETINGS To date, CDFA has held 75 public meetings Public meetings are held to inform and educate residents about ACP, HLB and the characteristics of the local infestation. 19

20 PRE-TREATMENT.NOTIFICATION Residents are notified of the treatment 48 hours before the scheduled treatment date Door-to-door notification 20

21 TREATMENT The treatment area is 400 meters around standard detection sites Only host plants are treated Pesticides Tempo SC Ultra (cyfluthrin), a contact insecticide that is applied to the foliage is used to treat adults and nymphs Merit 2F an imidacloprid insecticide will be applied to soil beneath the drip line of host plants to kill developing nymphs and adult psyllids 21

22 POST.TREATMENT.NOTICE 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 22

23 PROPERTIES.TREATED.FOR.ACP (Cumulative, 2008 to date) County Number Treated Imperial 10, 346 Los Angeles 33,988 Orange 2,669 Riverside 274 San Bernardino 1,750 San Diego 3,181 Ventura 142 Totals 52,350 23

24 ENVIRONMENTAL.MONITORING To Ensure Protection of Human Health and the Environment, the California Department of Food and Agriculture has contracted with the Department of Pesticide Regulation to oversee the environmental monitoring of eradication treatment projects Sampling Media include air, leaf, soil, tank, and water 24

25 TANK.SAMPLES Samples collected during treatment are used to confirm the proper mixture of the treatment pesticide. 25

26 IMIDACLOPID.SAMPLING Vegetation is sampled to ensure efficacy of imidacloprid application. Leaf material from selected properties is bagged and delivered to Dr. Frank Byrne at UC Riverside. Trees are sampled at least 6 weeks after treatment and again after 6 months. Results have been favorable with a high percentage of trees above the target value of ppb after 6 weeks. 26
