New UF/IFAS Plant Breeding Website
Fred Gmitter, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor of breeding and genetics, has released several mandarin citrus varieties. Most recently, he released the Marathon variety in 2018. The citrus fruit’s ability to hang onto the tree for an extended period led researchers to give it the Marathon moniker. Gmitter is one of numerous scientists …
Psyllid Study to Determine Degree of HLB Risk
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 …
Mutual Testifies on OJ From Mexico
Florida Citrus Mutual Executive Vice President and CEO Mike Sparks recently testified to federal officials regarding the effects of orange juice (OJ) imports from Mexico. His testimony to the United States Trade Representative (USTR), the U.S. Department of Commerce (USDOC) and the U.S. Department of Agriculture (USDA) was part of a larger hearing on trade with Mexico and the U.S. …
Infected ACP Found in California Commercial Grove Is No Surprise
For the first time, an Asian citrus psyllid (ACP) carrying the bacteria which causes huanglongbing (HLB) was found in a commercial grove in Riverside County. While the discovery has prompted concern, University of California Riverside Extension Specialist Monique Rivera said that the find has been expected and is not all that surprising. “We’ve had positive trees removed here in Riverside, …
Weird Trunk Disorders in Groves
Florida growers, Extension agents and others have been baffled by unusual trunk symptoms during what Evan Johnson termed “the year of the weird trunk disorder.” Growers spotted the disorders, which were similar to phytophthora, in groves over the past one and half to two years. Johnson addressed three of the disorders, which have been found in multiple counties. Johnson, a …
Survey to Help USDA Improve
A new U.S. Department of Agriculture (USDA) annual survey of farmers, ranchers and private forestland owners will help USDA understand what it is doing well and where improvements are needed. The survey will specifically help the Farm Service Agency (FSA), Natural Resources Conservation Service (NRCS) and Risk Management Agency (RMA). A selection of 28,000 producers will receive the survey over …
Cover Crops and Nematicides for Sting Nematode Management
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, …
Industry Split on OJ Marketing Order
A Florida citrus Industry Review Committee has divergent opinions about a possible federal marketing order for orange juice (OJ), Florida Citrus Mutual CEO Mike Sparks reported after the group met last week. “There were some that wanted to roll up their sleeves and continue work. There were a couple of committee members that had heard enough” and didn’t want to …
FDOC Efforts Successful in Moving More Juice
According to the Florida Department of Citrus (FDOC), sales of 100 percent orange juice (OJ) continue to show promising results. In the 4-week period ending Aug. 1, average year-over-year sales of total OJ increased 21 percent with 32.64 million equivalent gallons sold, per the latest Nielsen retail sales report. Sales of not-from-concentrate (NFC) OJ increased 27 percent for the period. …
Hurricane Season Forecast Updated to ‘Extremely Active’
Atmospheric and oceanic conditions are primed to fuel storm development in the Atlantic, leading to what could be an “extremely active” season. So say forecasters with the National Oceanic and Atmospheric Administration (NOAA) in its August update to the Atlantic Hurricane Season Outlook, initially issued in May. The 2020 Atlantic hurricane season is off to a rapid pace with a …
Alico: Orange Price Down but Outlook Positive
The average blended price per pound solid (PPS) for juice oranges grown by Alico, Inc. fell from $2.42 in the prior fiscal year to $1.86 in the current fiscal year. That was largely due to the Florida citrus crop being greater than expected in the 2018-19 harvest season, leading to excess inventory levels at Florida citrus juice processors, the company …
New Targets Found for HLB Treatments
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 …
CRDF Looking at Peptide for HLB
When news broke in July that University of California Riverside (UCR) scientists had found a peptide that might control HLB, Rick Dantzler quickly contacted lead UCR scientist Hailing Jin. Dantzler is chief operating officer of the Citrus Research and Development Foundation (CRDF), which was organized in Florida primarily to find ways to solve or cope with HLB. Jin had found …
