Researchers at the University of California, Riverside (UCR) claim they have made an important step in understanding the molecular mechanism of huanglongbing (HLB). They believe they have found the mechanism by which the disease evades detection and destruction by the natural immune system of citrus trees. HLB, or citrus greening disease, has devastated groves in Asia, South America and the …
By Len Wilcox California’s consistent sunshine makes for long growing seasons and allows tremendous varieties of foods to be grown, but it isn’t a perfect environment. Chronic water shortages create challenges for everything except cactus grown for tequila or jelly — but not many growers specialize in that. The rest of them, including citrus growers, have to deal with water …

The judge decided in favor of a lawsuit filed by 11 environmental activist groups and the city of Berkeley. Private citizens will still be able to use chemical insecticides on their property, but the order requires …
The sixth International Research Conference on Huanglongbing (IRCHLB VI) will be held in California. The conference has been scheduled for March 12-16, 2019, at the Riverside Convention Center in Riverside. This is the first time the conference will be held in California. Sponsored by the California Citrus Research Board (CRB) with the support of California’s citrus industry partners, the gathering …
The California State Water Resources Control Board (SWRCB) recently adopted significant revisions to the Eastern San Joaquin River Watershed Agricultural Order. The order will impact all irrigated regulatory programs statewide, including those that do not currently operate with a coalition system as in the Central Valley. Two years ago, the SWRCB released the first draft of revisions to the order …
On Jan. 1, 2018, the California Department of Food and Agriculture (CDFA) implemented an emergency regional quarantine to more effectively protect California citrus from huanglongbing (HLB) disease. The quarantine created seven zones: 1) counties where HLB has not been detected and are not next to citrus-producing counties or the Mexican border; 2, 3 and 4) counties widely infested with ACP …
California Citrus Mutual (CCM) joined with several other associations to oppose major changes proposed by the State Water Resources Control Board set to be adopted for the East San Joaquin Water Quality Coalition. The affected agricultural community and water quality coalitions expect the board to adopt the proposed revisions without substantial modifications at its Jan. 23 meeting. CCM and other …
By Len Wilcox When Jim Shanley retired from his highly successful career in commodity trading, he knew what he wanted to do and where he wanted to do it: farm specialty crops in the hills overlooking Morro Bay, California. His choice of crops, however, was not so clear. He started with avocados, but it was a curious little fruit from …
In an interview at the Citrus Research Board’s (CRB) annual conference last month, Karen Ross, secretary of the California Department of Food and Agriculture (CDFA), said the present status of huanglongbing (HLB) disease is similar to another disease that challenged the California citrus industry years ago. Pierce’s disease was a potentially devastating threat long before HLB. “One of the things …
Freeze alerts by phone will be available this winter for California citrus growers. California Citrus Mutual (CCM) is implementing a new system to help Central Valley growers stay updated on freeze alerts. Growers can sign up for text notifications to be alerted when the CCM Central Valley Weather Watch forecast is updated. This will include updates during critical nights. To …
Chlorpyrifos is being targeted again by environmental agencies. According to a press release from California Citrus Mutual (CCM), the California Environmental Protection Agency announced in mid-August that both California Department of Pesticide Regulation (DPR) and the Office of Environmental Health Hazard Assessment are pursuing new restrictions on chlorpyrifos. CCM says that chlorpyrifos is one of the most important and widely …
By Len Wilcox Ventura County, California, is perhaps the prettiest place in the world to grow lemons. Nestled between the golden slopes of the coast range and the relaxing seaside and azure-blue ocean, it is just north of Los Angeles on the famous Pacific Coast Highway. In town, Ventura seems far too urban to be an agricultural center; it is …
In a press release dated September 14, California Citrus Mutual (CCM) announced that the state’s current navel orange crop is down about 7 million cartons. This is approximately 10 percent of total production and is the second year in a row crop production has fallen.

Last month, the U.S. Department of Justice asked for dismissal of the lawsuit by California lemon growers challenging a new import rule allowing Argentinian lemons into the United States. The U.S. Citrus Science Council (USCSC), representing approximately 750 family citrus farmers, filed the lawsuit against the U.S. Department of Agriculture (USDA) in federal district court in Fresno, California, earlier this …
A new effort is underway in California to further regulate chlorpyrifos. On August 18, the California Department of Pesticide Regulation (DPR) issued a directive for interim mitigation measures to address health risks from the pesticide. This action marks the start of a public and scientific review of DPR’s revised draft risk assessment that could lead to increased restrictions statewide. At …
University of California (UC) scientists at the Lindcove Research and Extension Center (LREC) will soon begin to test the effect of growing citrus under protective screen (CUPS). CUPS is a proposed new method of controlling huanglongbing (HLB), or citrus greening disease, by keeping psyllids, small insects known to spread the disease, away from the trees. The test will evaluate the …
Eat citrus to prevent dementia? A new study published in the British Journal of Nutrition suggests just that. It shows that older people who frequently eat citrus fruit were 23 percent less likely to get dementia. The study was also reported by the American Association of Retired Persons (AARP) on its Brain Health and Wellness website. The study was conducted on more than …
A citrus tree in the city of Riverside tested positive for huanglongbing (HLB) disease. The detection is the first case of HLB found in a major citrus-producing county and the most northern in California. The California Department of Food and Agriculture (CDFA) confirmed the detection of HLB disease in a sample taken from a grapefruit tree located in a Riverside …
California citrus farmers have their ears perked for all news related to Asian citrus psyllid (ACP), huanglongbing (HLB) disease and HLB research, but some of the very latest advances have been available only in highly technical research journals, often by subscription only. University of California (UC) Cooperative Extension scientists are now translating the research into readable summaries and posting them …
