Total U.S. orange juice (OJ) production in the current 2021–22 season is forecast at 286 million single-strength equivalent (SSE) gallons, the U.S. Department of Agriculture’s Economic Research Service reported recently. If realized, this volume will be the lowest in more than 50 years. To compensate for lower production, U.S. OJ imports are expected to increase over last year, reaching more …
Gibberellic Acid Not Recommended in Spring for HLB Trees
By Tripti Vashisth Recent research has shown benefits of gibberellic acid (GA) application (monthly from September to January) in improving yield and canopy density of HLB-affected trees. These findings have caught the attention of Florida citrus growers. Many have indicated that they are applying GA in their groves as per the University of Florida Institute of Food and Agricultural Sciences …
Nutritional Lessons Learned From the Field and in the Wild
By Brad Turner In the 1970s, the majority of my family’s groves in Hillsborough, Polk and Hardee counties remained on a 25-foot by 25-foot setting or wider. Most of these “old school” blocks received several light cultivations in both directions, two fertilizations and two foliar sprays per season. These groves contained some of the most grand and bountiful trees in …
Citrus Commission Learns About HLB-Tolerant Trees, Other Research
At the Florida Citrus Commission meeting earlier this month, a federal scientist outlined an eight-step action plan for research and development of heirloom orange trees that appear to be tolerant to HLB. Brian Scully, director of the U.S. Department of Agriculture’s (USDA) Horticultural Research Laboratory, discussed the Donaldson and Tobias trees at USDA’s Whitmore Foundation Farm. A third tree is …
Extension Agents Still Seeing Damage From Freeze
It often takes time for the damage associated with freeze events to manifest in citrus. That was the case for the late January freeze in Florida. While some growers escaped fairly unscathed, others suffered significant damage. The damage began to show in the U.S. Department of Agriculture’s March citrus crop forecast. The agency lowered expected production of Florida oranges this …
Sneak Peek: April 2022 Citrus Industry
Increased attention on nutrition has become part of the overall strategy for managing HLB. The April issue of Citrus Industry magazine includes several articles on nutrient management designed to help growers keep trees productive in the HLB era. Mandarin growers will want to take note of new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research on how …
How to Reduce Bingo Tree Loss to Stem Dieback
By Christopher Vincent, Megan Dewdney and Liliana Cano Bingo mandarin hybrid is a variety with many promising characteristics, but it brings specific challenges to profitable production. One challenge identified early in the push to plant Bingo was stem dieback that led to tree loss. After looking into this problem for the past four years, University of Florida Institute of Food …
Battling Black Spot
By Megan Dewdney Editor’s note: This article originally stated that citrus black spot was in Hardee County. It should have said Hendry County, and has now been corrected. Citrus growers in Florida continue to battle new pests and diseases. They have been learning to manage citrus black spot for the last 12 years. The disease is still localized mainly in …
Florida Research Order Referendum Slated for May
Florida citrus growers will be asked to vote in a May referendum whether to maintain the Florida Research Order. The order was established in 1992 to support efforts by the industry — through the creation of the Florida Citrus Production Research Advisory Council (FCPRAC) — to develop solutions to production challenges. The research order has a six-year cycle and is …
OJ Is Half of Household Juice Purchases
Orange juice (OJ) recently accounted for more than half of the fruit juice purchased by households, Florida Department of Citrus (FDOC) economist Marisa Zansler told the Florida Citrus Commission on March 16. Citing a report on the Household Purchase Dynamics in the Beverage Category, Zansler added that grapefruit juice represented only about 1.5% of fruit juice sales. All fruit juice …
Georgia Citrus Association Emphasizing Food Safety
One bad apple can spoil the bunch. The same can be said for Georgia citrus. That was the message shared by Beth Oleson, director of food safety and education for the Georgia Fruit and Vegetable Growers Association, during the Georgia Citrus Association’s (GCA) annual meeting on Feb. 28. She spoke with growers about food safety and applauded GCA’s leadership. “We …
IPCs Improve Fruit Yield and Quality
By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
Growers in Northern Regions Whetting Consumer Appetites
Citrus production in North Florida, South Georgia and South Alabama continues to expand rapidly. That increased production led to a successful marketing year for producers, says grower Kim Jones, who owns a citrus packing facility in Monticello, Florida, and is part-owner of a similar facility in Tifton, Georgia. “We’re selling every piece of fruit we pulled into both sheds this …
Early HLB Detection by Dogs
By Amir Rezazadeh Huanglongbing (HLB), or citrus greening disease, has caused more than 70% decline in the production of oranges for juice and the fresh market in Florida. Once a tree is infected, there is no cure. Early detection followed by a rapid response is important to avoid further spread of the exotic pathogen. Delayed detection of HLB can result in …
HLB Update in Georgia
A small amount of citrus greening disease (huanglongbing or HLB) can escalate quickly if growers are not careful. Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautioned producers about the disease during the recent Georgia Citrus Association meeting. “The issue is not widespread yet (in Georgia) for sure,” said Oliver. “We don’t think the vector is …
Donaldson Tree Is ‘Beacon of Hope’
A recently discovered HLB-infected tree that is producing high levels of fruit holds hope for Florida’s citrus industry, according to Florida Citrus Commission (FCC) Chairman Steve Johnson. “By now, many of you have heard about the Donaldson tree,” said Johnson. “Recently rediscovered at USDA’s (U.S. Department of Agriculture) Whitmore Farm, this decades-old tree is abundantly producing early-season oranges and despite …
Soil Is Key to Setting Up Trees for Success
By Brad Turner As I started my regenerative journey five years ago, it conjured up memories of walking the family groves in the 1970s with my freshly sharpened eye hoe. I would follow the tractor as it pulled the offset chopper, crisscrossing between the widely spaced trees in all directions. The native grasses and broadleaf plants — including legumes like …
Mandarin Crop Losing Ground in Europe
In 2021–22, European Union (EU) mandarin production is forecast to decline 7.5% from the previous year to 2.9 million metric tons (MMT), according to the U.S. Department of Agriculture’s Foreign Agricultural Service. EU mandarin production may also be almost 5.5% lower than the 10-year average production of 3.1 MMT. The shortage in EU mandarin production is mainly the result of …
Who Should Be the Next Citrus Achievement Award Winner?
It is that time of year again when we seek nominations for the next Florida Grower Citrus Achievement Award winner. Since 2000, the honor has grown into the gold standard of industry recognition for those who have made and continue to make a significant impact within and even beyond the Florida citrus community.

Pointers for Pre-emergent Herbicide Use
By Ramdas Kanissery Weeds emerging in citrus rows are problematic as they compete for resources with the trees, support pests and interfere with grove operations like irrigation (Figure 1). Hence, effective strategies to control weed emergence should be in place. Pre-emergence (or residual) herbicides are an excellent tool for the long-term suppression of weeds in tree rows. These herbicides …
