Hesperidin and Good Health Linked
A new systematic review links hesperidin, a flavonoid found in oranges and 100% orange juice (OJ), to health benefits. However, more research is needed to further strengthen results. The Florida Department of Citrus (FDOC)-funded review examined published studies relating to hesperidin in 100% OJ and its impact on several chronic conditions and other measurements. Those measurements included blood levels …
Morocco Developing New Citrus Varieties
The National Institute for Agricultural Research (INRA) in Morocco is developing new early- and late-season harvest varieties to support a prolonged production season, the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reported. This will allow producers to supply markets for longer periods of time and help Morocco remain competitive in international markets. In May, INRA launched a call …
EU Citrus Production on the Rise
Citrus production in the European Union (EU) is expected to rise 10.4% in the 2020-21 season to 11.7 million metric tons, according to the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS). The FAS June report attributed the production increase to favorable weather conditions and rebound production mainly in Spain and Italy following a significant drop in 2019-20. “EU citrus …
PIECES OF THE PAST: Orange Guards
By Brenda Eubanks Burnette We received a request for information several months ago from researcher/historian Jono Miller regarding an old production practice of leaving cabbage palms in citrus groves as “orange guards.” The trees helped protect groves from freezing due to the creation of a canopy to keep the heat from the land rising during cold weather. In his new …
Making Sense of Biologicals: Improve Fruit Size and Quality
Citrus growers need as many tools in their toolbox as possible. With the Florida citrus industry decimated in recent years, mainly due to citrus greening disease, growers are exploring all options to help them succeed. CYAN 365®, a biostimulant from C Green Ag Biotechnology, is one tool that has proven to help enhance the quality and size of citrus crops, …
Fruit Drop Is Biggest Grower Concern
Fruit drop “is probably the No. 1 concern” of the citrus growers he knows, says Ray Royce, executive director of Highlands County Citrus Growers Association (HCCGA). “Fruit drop and profitability are going hand in hand,” he adds. “There’s a tremendous struggle now to be profitable, given the relatively low harvest numbers,” Royce says. “I think growers believe that if they …
Root Depth Isn’t What It Used To Be
By Evan Johnson, Tanyaradzwa Chinyukwi, Lorenzo Rossi and Davie Kadyampakeni Huanglongbing’s (HLB) detrimental effect on roots has changed how we think about root health and horticultural management of citrus in Florida. As part of the work studying nutritional responses described in Effect of Nutrients on Canopy Response and Yield, we are studying the effects of macronutrient and micronutrient fertilization on …
Study: Beverage Labels Confuse Parents
Beverage labeling regulations appear to fall short of helping parents identify the ingredients of drinks they purchase for their children, a recent study published in Pediatric Obesity suggests. This has researchers calling for changes to labeling regulations to increase transparency and help consumers choose healthier beverages. The online study included more than 1,600 parents who had healthy 1- to 5-year-old …
Understanding Physiological Fruit Drop of Citrus
By Tripti Vashisth, Megan Dewdney and Lauren Diepenbrock Citrus flowers profusely, but less than 2% of the flowers become harvestable fruit. In other words, 98% of the flowers seen during bloom will end up on the grove floor at some point during fruit development, whether as a flower, fruitlet, young fruit or mature fruit. Profuse flowering allows trees to produce …

Effect of Nutrients on Canopy Response and Yield
By Davie Kadyampakeni, Tanyaradzwa Chinyukwi, Alan Wright and Rhuanito Ferrarezi The development of an efficient nutrition program for citrus trees provides the essential elements for optimum tree growth and yield. Tree performance is reduced when an essential element is deficient, while an excessive amount leads to plant toxicity and hinders overall tree performance. In citrus production, adequate fertilization rates help …
