Citrus Health Response Program
The Citrus Health Response Program (CHRP) began in response to establishment of citrus canker and huanglongbing (HLB or citrus greening) in Florida, and the potential for other pests and pathogens to enter US citrus production areas. The program focuses on citrus disease management using harmonized production standards across all citrus producing states. A technical working group (TWG), reviews, defines, and identifies conditions under which nursery stock may be shipped to non-citrus producing states with no (or very low) risk of spread of citrus canker, HLB, or Asian citrus psyllid, the vector of HLB.

Light Brown Apple Moth
The light brown apple moth (LBAM), Epiphyas postvittana, was detected and confirmed in Alameda County, CA, in March 2007. If left uncontrolled, LBAM could cause significant damage to many different crops, including stone fruits, pome fruits, grapes, and citrus. CPHST chairs a TWG of scientists from the United States, Australia, and New Zealand to look at potential eradication/control options, develop management recommendations and research needs, and provide ongoing scientific input to program operations. In 2009 CPHST appointed a national coordinator for LBAM research and established a facility in California to develop sterile insect technology for the pest and support the goals of the program.

Potato Cyst Nematode
A technical working group (TWG) for potato cyst nematode (PCN), Globodera pallida, was convened to make management recommendations based on current scientific knowledge and expertise in response to the detection of PCN in a localized outbreak in Idaho potato fields. The PCN TWG provided scientific support to the regulatory program based on timely information as the response and resulting infrastructure developed. The TWG also supported issues related to survey and detection of PCN in a national survey for this pest. After the discovery of potato cyst nematode in Idaho, the area was quarantined and fumigated. Since the nematode can remain dormant for long periods, methods were developed to eradicate the nematode by planting oil radish as a biofumigant. A national survey and trace-back investigations began in 2007 and continues indefinitely. Currently, there are no other detections. (Contact Russ Bulluck)
Phytophthora ramorum
CPHST provides on-going scientific support, including participating in science panel meetings and recommending modifications to eradication protocols made necessary as new scientific information becomes available. Rapid incorporation of new scientific developments continues to be a major driver of our response and recovery efforts. (Contact Russ Bulluck or Charla Hollingsworth)
