By Ute Albrecht, Sameer Pokhrel and Kim D. Bowman The rootstock has received increased attention as a management strategy to alleviate the devastating effects of HLB. In commercial citrus nursery production, rootstocks are typically propagated by seed. This is possible because citrus produces polyembryonic seeds with nucellar embryos, which develop into plants that are genetically identical to the mother plant. …
University of California Riverside Extension Specialist Monique Rivera said that funding for a new research project to study the Asian citrus psyllid (ACP) has been approved. The project will take a closer look at the phenology of huanglongbing (the citrus disease ACP spreads) and its prevalence in psyllid populations. The scientists will be looking for patterns that will help them …
August brings a special episode of the All In For Citrus podcast as listeners hear from the new leader of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and get an update on digital offerings. Citrus Research and Education Center Director Michael Rogers starts the episode by announcing a redesign to the UF/IFAS Citrus Research website. The …
Global production of non-orange citrus — tangerines/mandarins, grapefruit, lemons and limes — in 2019-20 is estimated to be lower than the previous year, according to the U.S. Department of Agriculture’s Foreign Agricultural Service. TANGERINES/MANDARINSGlobal production is estimated down 400,000 tons for 2019-20 to 31.6 million with declines in the European Union (EU), Morocco, Turkey and the United States more than …
By Larry Duncan, Johan Desaeger and Sheng-Yen Wu The citrus row middle habitat changed profoundly beginning in the 1970s as mowing replaced disking for weed management. This change ended the costly cycle of cutting and regrowing citrus roots near the soil surface and reduced soil erosion, among other benefits. Mowing also allowed a seasonal succession of native plants to flourish, …
According to the Florida Department of Citrus (FDOC), sales of 100 percent orange juice (OJ) continue to show promising results.

Citrus growers can get continuing education units (CEUs) from the 2020 Florida Citrus Growers’ Institute, even though the in-person version of the annual event was cancelled due to COVID-19. Multi-county citrus Extension agent Chris Oswalt discusses how growers and others can get their restricted-use pesticide license or Certified Crop Advisor CEUs. “We have started to receive those presentations from those …
Thanks to recent advances in metabolic modeling, scientists are closer to gaining the upper hand on citrus greening (also known as huanglongbing or HLB), a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable. Metabolic models of organisms are like road maps of …
Feral citrus growing in natural hammocks reveals insights about production and HLB. By Christopher Vincent and Anirban Guha Would you rather go outside in August and stand for a few hours in the sun or in the shade? It turns out citrus prefers the shade, too. In the past two years, we have been researching the health of citrus growing …
Global orange production for 2019-20 is estimated to fall 7.8 million metric tons (MMT) from the previous year to 46.1 MMT, according to a July report by the U.S. Department of Agriculture’s Foreign Agricultural Service. Consumption is forecast to be flat, though not down. Global trade is expected to be lower with an anticipated drop in exports from Brazil and …
California citrus growers and other farmers in the Bakersfield area may feel vindicated with the result of a new study by researchers at Duke University and RTI International. As reported in the California Department of Food and Agriculture Planting Seeds blog, the study finds that reusing oilfield water that’s been mixed with surface water to irrigate farms in the Cawelo …
The European Union (EU) tangerine crop forecast for 2019-20 shows a 14 percent decrease from the previous year, to 2.7 million metric tons (MMT), the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) recently reported. The expected production is 13 percent lower than the nine-year average production of 3.1 MMT. The FAS reported that the EU has reduced its tangerine …
Global orange juice production for 2019-20 is estimated to slip 23 percent from last season, to 1.6 million tons, according to the U.S. Department of Agriculture’s Foreign Agricultural Service. Much of the blame falls on Brazil and Mexico, where fewer oranges are expected to be available for processing. Worldwide orange juice consumption is projected to be flat, though not down. …
A projected decline in Spain’s grapefruit crop in 2019-20 will lead to an 11 percent decline in the all-European Union (EU) grapefruit forecast compared to last season. EU total production is pegged at 96,720 metric tons (MT). Other EU grapefruit-producing countries will increase or maintain production. That’s according to a recent report from the U.S. Department of Agriculture’s Foreign Agricultural …
Grower meetings have been curtailed due to COVID-19, but Extension agents and specialists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are available to assist growers needing in-person help. “We do have the ability to get out and travel and come see folks,” says Citrus Research and Education Center (CREC) Director Michael Rogers. “If there are …
By Manjul Dutt and Jude Grosser Finger lime, a distant relative of sweet orange and grapefruit, is a relatively new crop species for Florida. It is an Australian native species that has been gaining in popularity and importance in the last few years because of its unique fruit characteristics and disease tolerance, which sets it apart from conventional sweet orange …
A snail causing problems in Highlands County and South Florida groves “appears to be popping up all over the state,” said entomologist Lauren Diepenbrock. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher identified the snails as Bulimulus sporadicus. “It was first documented in Florida in 2009,” Diepenbrock said. “Citrus is not the only crop to be …
July’s All in For Citrus podcast episode focuses on online educational opportunities for growers as in-person events continue to get canceled due to COVID-19 restrictions.

Rogers says more researchers are …
As demand increases for a cure to huanglongbing (HLB), experts are studying the most effective ways to control the damaging citrus disease. A research project funded by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is focusing on the effects of oak leaf extracts on CLas-infected citrus trees. CLas (Candidatus Liberibacter asiaticus) is the bacteria the causes …
