California Citrus Pest and Disease Prevention Program Continued for Another Four Years (Jul 30, 2013)
California Department of Food and Agriculture.
The California Department of Food and Agriculture has extended the California Citrus Pest and Disease Prevention Program for an additional four years. The extension came after several public hearings and a comment period that indicated overwhelming support for continuing the program among stakeholders. The program was created by legislation in 2009, establishing a mechanism for citrus producers to assess themselves to provide support for ongoing efforts to protect against citrus threats such as the Asian citrus psyllid. The psyllid is a pest that spreads the bacteria causing huanglongbing (HLB), or citrus greening, a fatal disease of citrus trees for which there is no cure.
UC Davis Scientists Assemble 5 Acres of Mats for Tahoe Asian Clam Project (Oct 16, 2012)
University of California - Davis.
Rubber barriers bound for the lakebed of Lake Tahoe's Emerald Bay are being assembled at the University of California, Davis, as part of the biggest Asian clam control project in the lake's history. The Asian clam control project is scheduled to begin on October 15 (weather permitting) and deployment of the bottom barriers will take from four to six weeks to complete. The barriers will be left in place for approximately one year in order to achieve clam mortality. Crews will return for three weeks in September-October of 2013 (after Labor Day) to remove the barriers. Work will primarily occur in early mornings to minimize interference with recreational boating; however, boaters entering Emerald Bay may be asked by on-site coordinators to delay their entrance into the bay for a short while to ensure diver safety. Work will only occur during the week, with no work occurring on the weekends or holidays, and has been scheduled not to interfere with the summer boating season. Boaters planning to visit Emerald Bay during these periods are asked to take extra precautions to avoid disrupting the control project or endangering the divers.
Disease Huanglongbing Detected in Hacienda
Heights Area of Los Angeles County (Mar
Citrus Research Board. Citrus Pest & Disease
confirmed the presence of citrus
greening, also referred to as Huanglongbing,
in an Asian
citrus psyllid (ACP) sample and plant
tissue samples collected from a lemon/pummelo
tree in a residential neighborhood in Hacienda
Heights, Los Angeles County, California.
This is the first confirmation of the disease
in California. APHIS is
working closely with the California Department
of Food and Agriculture (CDFA), County Agricultural
Commissioners, and the California citrus
industry to plan and implement communication,
response, and regulatory activities in the
affected area. CDFA collected the samples
during ongoing citrus surveys conducted as
part of the cooperative Citrus Health Response
CDFA has set up a hot line for
residents who suspect they may have infected
trees - (800) 491-1899.
California Invasive Plant Council.
CalWeedMapper is a new Web site for
mapping invasive plant spread and planning
regional management. Users generate a report
for their region that synthesizes information
into three types of strategic opportunities:
surveillance, eradication and containment.
Land managers can use these reports to prioritize
their invasive plant management, to coordinate
at the landscape level (county or larger) and
to justify funding requests. For some species,
CalWeedMapper also provides maps of suitable
range that show where a plant might be able
to grow in the future. The system was developed
by the California
Invasive Plant Council and is designed
to stay current by allowing users to edit data.
Additional Funding to Combat European Grapevine
Moth in California (PDF | 39 KB) (Feb 24, 2012)
Animal and Plant Health Inspection Service.
Animal and Plant Health Inspection Service
has announced the availability of $8 million
in emergency funding
to prevent the spread of European
Grapevine Moth (EGVM) in California.
The destructive moth was found in the Napa
Valley of California in Oct 2009, which was
the first occurrence of this moth in the
U.S. and North America. EGVM is a serious
pest of grape, feeding on the flowers and
bunches. See European
Grapevine Moth information from the California
Department of Food and Agriculture for more
