Breaking News: New HLB Infected Tree in San Gabriel

Citrus Insider Reports New HLB Confirmed in San Gabriel

Today, two additional trees in have tested positive for Huanglongbing (HLB). The two trees, an orange and a kumquat, are on separate properties but are both within the core area in San Gabriel where 10 diseased trees were confirmed last summer. Given the close proximity, there will not be a quarantine expansion.

One of the HLB-positive trees has already been removed and California Department of Food and Agriculture (CDFA) officials are in the process of contacting the other homeowner to schedule tree removal. Agriculture officials are working quickly in the area.

Citrus trees in San Gabriel had already been treated for the Asian citrus psyllid (ACP) within the last few weeks as part of CDFA’s routine HLB response. ACP populations are closely monitored in areas where HLB has been detected and treatments occur if there is a noted increase in population size. Since trees have been recently protected, no additional treatments will take place at this time. Instead, CDFA will focus on sampling extensively in the area. Much of the area has already been sampled and CDFA’s lab has identified all samples from San Gabriel as high priority.

The Citrus Pest & Disease Prevention Program is working with the Los Angeles County Agricultural Commissioner’s office and CDFA to develop a multilingual informational flyer to notify residents of the significance of these finds and potential implications to other citrus trees in the area. CDFA staff will distribute this information as they go door-to-door sampling and surveying.

More information will be shared as it is available. In the meantime, the citrus industry is encouraged to keep a critical eye on all plant material moving into or out of your groves and recommends taking the following steps so collectively, as a team, we can all save our citrus trees.

-Remove all leaves and stems

-Shake out picking bags

-Inspect harvesting equipment

-Educate fieldworkers

-Get on board with area-wide treatments

Ventura County ACP Report Less Than Uplifting

Joanne O’Sullivan, a licensed PCA and QAL (Qualified Applicator), and a Citrus Pest & Disease Prevention Program Grower Liaison in Ventura County, reported TODAY that four new urban settings with 25 or more citrus trees on the property have been discovered in Asian citrus psyllid treatment areas in recent weeks. These four finds are within the same area as the commercial Camarillo find in March.

CDFA deems these orchards also as commercial; therefore, the homeowners are financially responsible for the treatment.

O’Sullivan said, “The first two homeowners I contacted were more than willing to cooperate and take on the financial costs of spraying. They understand it is necessary for the benefit of both their trees and the health of Ventura County’s citrus industry. The third homeowner opted to remove 15 of his trees and CDFA then sprayed the remaining ten. The last and remaining homeowner will take a bit more convincing, but I am confident they will come to see the great benefits of working with us.”

“On a less uplifting note,” O’Sullivan continued, “it has been an unlucky month for Fillmore and Piru producers. Piru has been hit again in the Bardsdale area with two ACP confirmations in the same week. These same growers had completed the ACP psyllid spray protocol in November of last year. It goes without saying that the producers are less than delighted to be repeating treatment again so soon.”

She reiterated a very important element in the ACP/HLB program,
”The goal of the [Ventura County ACP-HLB] Task Force has been to delay as long as possible the introduction of HLB into Ventura County. As a result of the progressive and aggressive work from producers, packers, pest advisors, operators and the CDFA and county trapping programs, Ventura remains one of the most successful ACP/HLB programs in the state.

A critical element of ACP treatment protocol for organic growers is the importance of scouting post-treatment. All blocks must be aggressively monitored following applications, using the sampling protocol that is included in the ACP CONFIRMATION IN YOUR AREA packet.

Current protocol requires organic producers to sample every two weeks after the third treatment. Sampling every two weeks allows the grower to document control. Early detection and swift eradication is our best defensive against the introduction of HLB and its devastating effects on Ventura citrus producers.

Every producer – commercial and organic – should be familiar with the signs of Asian citrus psyllid. Literature on identifying ACP is available at the CRB, UCIPM, UC Cooperative Extension as well as from CDFA. Share it with your workers. If you have any doubts about your ability to identify adults, nymphs, and eggs, please contact me, I am always glad to meet with you on your ranch and help you scout.

In closing, I was forwarded an interesting short news article outlining the economic hit Florida has taken as the result of HLB, with annual production dropping from 1,000,000 boxes of fruit to 750,000. This news story is a not- so-gentle reminder of why it is vitally important that everyone working together in a cooperative spirit can keep Florida’s scenario from happening in California.

And let’s all keep up the diligent efforts that help keep Ventura’s citrus industry strong.

The California Citrus Pest & Disease Prevention Program is a grower-funded program administered by the Citrus Pest & Disease Prevention Committee, which was established 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.

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 and disease detection, treatment and educational outreach programs.

Crop Safety: How You Can Prevent the Spread of the Asian Citrus Psyllid

A new video aims to educate California citrus industry workers on what they should be doing in the field to limit the spread of the Asian citrus psyllid.

The three-minute video produced by the Citrus Pest & Disease Prevention Program demonstrates the best management practices needed to limit the spread of the psyllid and protect crops.

As the video mentions, the Asian citrus psyllid feeds on  leaves and stems of citrus trees, and properly managing this plant material will help avoid accidentally transferring the psyllid from one work site to the next.
