“The local market has improved since last season,” says citrus grower Chip Henry. “I’ve gained customers, and existing ones are buying more. When people know the fruit is being harvested, they seek out that local supply and want to support their local farmers.” Henry grows 12 acres of organic Valencias at McGuire Groves in Apopka, Florida, and sells his fruit …
An Alternative Approach to Citrus Greening
“Life as a citrus grower is a perilous journey,” says Chip Henry. Among the toughest perils the third-generation Florida grower has endured are the freezes of the 1980s, the threat of losing his land to highway construction, and the scourge of citrus greening. Henry’s story begins with the founding of O.E. McGuire Groves in Apopka by his maternal grandparents in …
Integration of Nutrition and Crop Protection Products
By Davie Kadyampakeni and Evan Johnson In the era of citrus greening disease (huanglongbing, HLB), maintaining optimal nutrition and disease/pest management strategies is critical for avoiding adverse effects on tree performance. Use of the right fertilization rate, timing and placement are important for optimal citrus production. In a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research study, …
Updates From Florida Citrus Mutual
The Florida Citrus Mutual (FCM) board of directors voted earlier this month to support the continuation of the Florida Research Order. It encouraged Florida citrus growers to vote for continuation in a May referendum. The board acted after hearing from Citrus Research and Development Foundation (CRDF) Chief Operating Officer Rick Dantzler and discussing the importance of a continued funding mechanism …
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 …
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 …
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 …
A Citrus Servant
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP It’s not unusual for the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to have a dozen contacts with Peter Chaires in a day, between the emails, calls and visits. Chaires serves as executive director of the New Varieties Development & Management Corp. (NVDMC), executive vice president of Florida Citrus Packers and …
Trial Confirms Benefits of IPCs
Individual protective covers (IPCs) on citrus trees have become a more common sight in Florida groves in recent years. The bags that cover young trees exclude the Asian citrus psyllid (ACP) from feeding on the plants, thus protecting them from HLB. Some estimates suggest that more than 1 million IPCs are now deployed in the state’s citrus groves. During the …
Lower Supply, Higher Demand and Processed Orange Prices
By Ariel Singerman According to the U.S. Department of Agriculture (USDA), production of processed oranges in Florida will decline again this season (Figure 1). If such a forecast materializes, production will have declined by approximately 80% since HLB was first found in the state. The Florida Department of Citrus reports that, as a consequence of COVID-19, orange juice demand has …
The State of the Citrus Industry in Japan
In a short summary about citrus in Japan, the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reports that the country’s mandarin production continues to decline amid labor shortages and reduced consumption. Shipping challenges and rising prices are projected to reduce the consumption of largely imported oranges and grapefruit. MANDARINSTangerine/mandarin production for 2021-22 is forecast at 924,000 metric tons (MT), …
Gibberellic Acid Application on Hamlin Appears Promising
By Tripti Vashisth In a multi-year field trial, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have seen beneficial effects of gibberellic acid (GA) on Valencia sweet oranges. Monthly application of GA (September to January) on Valencia improved yield on average by 30%, reduced fruit drop and elicited enhanced plant defense response. These benefits are possibly due …
Florida Growers Report Early-Season Obstacles
By Frank Giles The U.S. Department of Agriculture (USDA) reported a drop in estimated Florida orange production in its December crop update. That estimate lowered production by 1 million boxes from the initial forecast of 47 million boxes reported in October. In advance of USDA’s January estimate, Florida citrus growers discussed how their crops are progressing. Here’s what they had …
Pest Management: A New Approach to an Age-Old Challenge
By Brad Turner From a family with deep Florida roots, I have over 40 years of experience in commercial citrus production. I learned the industry from the ground up by working in the family groves while studying citrus production at Florida Southern College. I have owned a citrus nursery, my own groves and a citrus caretaking business. I have also …
Updated Brazilian OJ Projection
The total Brazilian frozen concentrated orange juice (FCOJ) 65 Brix equivalent production for 2021-22 is projected at 1.123 million metric tons (MMT). That projection, which is an increase of 16% compared to orange juice production for 2020-21, was made by the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS). The São Paulo industry is expected to process 265 million …
Covers Prevent Psyllids and HLB
About four years ago, Fernando Alferez started to test whether citrus trees grown inside protective mesh covers could be kept safe from the HLB-spreading Asian citrus psyllid. New research from Alferez shows that citrus trees grown under individual protective covers (IPCs) show no signs of HLB, also known as citrus greening. Specifically, scientists found that psyllids cannot penetrate the IPCs …
Pummelo Interstocks Could Improve Performance of HLB Trees
By Manjul Dutt, Ethan Nielsen, Lamiaa Mahmoud, Maria Quirico and Jude Grosser All commercially cultivated citrus scion varieties are grafted onto rootstocks before being planted in the field. The rootstocks are selected based on specific desirable qualities (abiotic/biotic stress resistance) and the ability to produce a good crop in a specific location. The ideal rootstock confers disease resistance, hardiness, tolerance …
Florida Citrus Packers: Fix Grapefruit Import Action Now
Florida Citrus Packers recently called for a fix to a so-called “patch” by the U.S. Department of Agriculture (USDA) that allegedly creates unfair advantages for Mexico and other countries over domestic grapefruit producers. Citrus Industry previously reported that the agriculture commissioners for Florida and Texas wrote letters protesting the USDA action. Florida Citrus Packers Executive Vice President Peter Chaires …
Sneak Peek: December 2021 Citrus Industry
Everyone seems to get busier during December as the holidays near. With the harvest season in full swing, this is especially true in the Florida citrus industry. Amidst the rush to complete holiday preparations and tend to never-ending grove tasks, it’s a good idea to pause for a moment to consider farm safety issues. The December issue of Citrus Industry …
