Task Force ACP-HLB update
To date, 232 residential citrus trees in Southern California have tested positive for the HLB bacterium. All have been, or are being, removed. Most were in neighborhoods in LA and Orange counties. Three of the trees were in Riverside, and although they were residential trees, the resulting 5-mile radius quarantine for HLB is affecting a few growers in Riverside and San Bernardino counties.
The latest HLB quarantine map with the running tally of HLB detections in the state can be found at the Citrus Insider website: https://citrusinsider.org/maps/. The maps are updated every week.
As HLB detections increase and spread closer to commercial citrus, it is a good time to consider removing any citrus trees that are unloved, uncared for, or not worth the time and resources required to protect them from ACP and HLB. Untreated citrus can serve as a reservoir for ACP and possibly the disease HLB, increasing the risk to other citrus in the area. The Citrus Matters ACT NOW program may be able to assist with tree removal at little or no charge to you. Find more information at: https://citrusmatters.cropscience.bayer.us/commercial-grower/act-program. Or if you need referrals for tree removal services, contact Sandra or Cressida.
ACP-HLB program meetings
The California Citrus Pest & Disease Prevention Committee (CPDPC) is made up of growers and other representatives of the citrus industry, working with the California Department of Agriculture (CDFA) and others. The CPDPC is funded in large part by grower assessments and steers the statewide effort to protect our citrus from ACP and HLB. The full committee meets every other month, with subcommittees meeting in between. All committee and subcommittee meetings are public and open to anyone to attend or listen remotely via computer or phone. Agendas for upcoming meetings and minutes from previous meetings are posted on the CDFA website: https://www.cdfa.ca.gov/citruscommittee/.
Coastal citrus representative needed for CPDPC
There is an opening for a grower representative from the coast to serve on the CPDPC. Be a part of deciding how grower funds are spent to protect our industry. Details can be found here: https://www.cdfa.ca.gov/egov/Press_Releases/Press_Release.asp?PRnum=17-069.
Santa Paula crew boss workshop

This Spanish-only workshop for crew bosses, ranch managers, etc., focuses on preventing human-aided spread of ACP and HLB. It has been approved by the Department of Pesticide Regulation for 2 hours of continuing education in the "other" category. For details see:

'Hass' avocados are now being imported from Colombia. The US consumption of avocados has increased from about a pound per person per year in 1980 (mostly consumed in California, Florida, Arizona, Texas and Hawaii) to over 7 pounds today and eaten in most states in the country. Avocado sales in the US amounted to 350 million pounds 20 years ago, and California was the major grower and supplier of that fruit. But now consumption surpasses 1.5 Billion pounds. California production now is dwarfed by imports. The US has become a source of green gold for exporters. We are importing them from many countries: Mexico, Chile, Peru, Dominican Republic and New Zealand. Colombia is just the latest to start exporting here. Other countries are angling to ship here, as well. And not only has the US discovered avocado, but consumption is increasing world-wide and China is a major player, too.
Many countries are seeing the opportunity and plantings are also increasing many in environments that really aren't appropriate for the 'Hass' where it may be too hot, too cold, too humid or too dry. 'Hass' is a picky fruit that likes it just right. But not only is China becoming a major consumer of the fruit, it is now becoming a new producer of this fruit.
