The Auburn University Plant Diagnostic Clinic provided the initial diagnosis of SOS, and USDA Animal …
University of California Riverside (UCR) is committed to a major offensive against huanglongbing (HLB, or citrus greening disease), as the threat is marching ever closer to commercial citrus orchards in California. The only confirmed cases in Southern California have been in residential trees in Los Angeles and Orange counties, including near the UCR campus. But some experts believe it is …
By: Brad Buck, 352-294-3303, bradbuck@ufl.edu GAINESVILLE, Fla. — Grapefruit grows better under screen houses than in unprotected groves because the indoor facilities keep out the insect that causes citrus greening, new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows. Protecting citrus from greening is essential, UF/IFAS researchers say. The disease, first detected in Florida in 2004, …
An approximately 35-acre research plot that fell victim to citrus canker years ago will soon become a new research site helping growers pick trees that fare best with HLB. The plot at the Indian River Research and Education Center (IRREC) in Fort Pierce will keep its former name, the Millennium Block. University of Florida Institute of Food and Agricultural Sciences …
By Arnold Schumann, Laura Waldo, Alan Wright and Rhuanito Ferrarezi Authors’ note: This article was written before Hurricane Irma passed through Florida. We are still assessing the full impact and implications of storm damage to both University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus undercover production systems (CUPS) facilities and will provide updates in future articles.

In a wide-ranging talk at Citrus Expo in August, University of Florida Institute of Food and Agricultural Sciences researcher Fred Gmitter discussed many topics important to growers. Subjects included making variety decisions when planting, surviving HLB, and the potential for lemons in Florida. He summarizes his discussion: “We can give information (about citrus varieties), but we don’t want to give …
By Beverly James, Alec Richman, Brad Buck, Samantha Grenrock and Tom Nordlie The year was 1917. In April, the United States entered World War I. Florida’s population was fast approaching 1 million, and agriculture was the state’s most important economic driver. Citrus cultivation, introduced to Florida 400 years earlier by Spanish explorers, had spawned an industry following the Civil War. …
By Stephen H. Futch and Ariel Singerman In May of 2017, we visited the northwestern citrus production region of Argentina in the provinces of Jujuy, Salta and Tucumán. The purpose of the trip was to learn more about Argentina’s citrus industry and programs being developed to deal with both the Asian citrus psyllid (ACP) and huanglongbing (HLB). Argentina has a …
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 …
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 …
By Jude W. Grosser and Frederick G. Gmitter It’s no secret that citrus greening disease, or HLB, continues to take a heavy toll on the beloved Florida citrus industry. It has been estimated that the industry will need to replant over 3 million trees per year for the next 10 years just to get back to normal. So the million-dollar …
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 …
By Richard F. Lee The old-timers called citrus leprosis “nailhead rust.” Prevalent in Florida in the early 1900s, the disease was first called leprosis in the 1920s by H.S. Fawcett. Although the disease was widespread in Florida at one time, it mysteriously disappeared in the mid-1960s. L.C. Knorr [University of Florida/Institute of Food and Agricultural Sciences Citrus Research and Education …
By Hassan Farouk Ahmed Morocco’s citrus production reached 2.3 million metric tons (MT) in 2016–17, an increase of 15 percent over the previous marketing year. Orange production increased by 4 percent, to 962,250 MT, while tangerine and mandarin production increased 24 percent to 1,325,246 MT. Much of the increase in production was due to increases in the area harvested, as …
By Arnold Schumann and Laura Waldo Florida citrus trees may require irrigation throughout the year due to the extremely sandy soils with low water-holding capacities and the warm subtropical climate with distinct drought periods in spring. Citrus trees are evergreen and may be actively growing at any time, with no true dormant phase. HLB-affected trees are particularly prone to multiple …
By Tacy Callies With the recent birth of the Georgia Citrus Association (GCA), many small commercial citrus groves are getting started in the state. Georgia’s newest citrus planting, however, is not a commercial grove. It’s a 100-tree installation that was planted this spring at the Mitchell County Correctional Institute. Dubbed MitCo Grow by a 4-H student, the project is the …
Professor Patrick Brown, of the University of California, Davis Department of Plant Sciences, needs the help of some citrus growers with high-producing citrus orchards for a special project. He is looking for growers who have both navels and mandarins that are productive. “It’s a non-destructive study. We just want to collect leaf samples and analyze them for nutrient levels,” said …

By Jim Graham and Kelly Morgan Huanglongbing (HLB), greening and yellow shoot are names for the most devastating citrus disease in the world. Symptoms of HLB include a distinctive chlorotic mottle on fully expanded leaves. Infected shoots are stunted, and branches gradually die back as the symptoms appear in other sectors of the tree canopy. HLB reduces fruit size, weight …
