News for citrus growers around the globe
By Brenda Eubanks Burnette In January, the Florida Department of Agriculture and Consumer Services (FDACS) hosted virtual “Florida Citrus Squeeze” events at elementary schools throughout Florida with Chef Paula Kendrick and Miss Florida Citrus Leila Sabet. The program was announced in December to Florida food service personnel and teachers that participate in the division’s Harvest of the Month Program. Participating …
The citrus industry is expanding in Georgia. With that growth comes the need to slow the spread of the Asian citrus psyllid (ACP), the vector of HLB disease. Although not yet found in Georgia’s commercial citrus production, there have been confirmed HLB-positive residential citrus trees. The disease has the potential to greatly hinder the state’s citrus industry. Therefore, University of …

Citrus fruit drop before harvest has been a perennial problem for Florida growers but has been particularly challenging this season. Tripti Vashisth and Fernando Alferez of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will present their latest research on fruit drop and answer questions from growers in a Zoom seminar on Feb. 16. The seminar is …
Citrus Extension agent Chris Oswalt reports the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is determining the acclimation of Florida citrus trees to cold weather by measuring citrus leaf freezing temperatures. “Certain environmental conditions will initiate this acclimation process,” says Oswalt. “These environmental cues will cause physiological changes to occur within the plant that will depress the …
By Megan Dewdney, Tripti Vashisth and Lauren Diepenbrock Dead wood has long been challenging for fresh citrus fruit production. Spores in twigs can form which cause blemishing diseases that downgrade fruit for lower profits. More recently, it has come to light that there are horticultural and entomological reasons to remove this wood as well. Many growers are familiar with melanose, …
By Clint Thompson Increased interest in biologicals stems from their long-term sustainability and the belief that synthetic materials have reached their ceiling of productivity. Tate McPherson, vice president of marketing and business development at Douglas Plant Health (DPH), shares those sentiments about biologicals, which represent a group of products derived from living organisms. Farmers utilize these environmentally friendly products in …
By Ajia Paolillo Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. Integrated pest management (IPM) uses a combination of methods to keep pest populations at an acceptable level, which are economical …
Mike Sparks, Florida Citrus Mutual executive vice president/CEO, reported that the U.S. Department of Agriculture (USDA) announced another round of citrus purchases totaling almost $48 million. The breakdown includes $10 million worth of orange juice, $7.5 million worth of grapefruit juice, $25 million in fresh oranges and $5 million in fresh grapefruit. The USDA purchases will be for distribution to …
Visual identification of nutrient deficiencies and leaf damage is an important diagnostic tool for fine-tuning management of citrus. Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, shared how UF/IFAS researchers have used artificial intelligence (AI) to diagnose citrus nutritional deficiencies, diseases and pest damage. According to Schumann, disease and pest symptoms on leaves may cause …
By Brenda Eubanks Burnette I grew up in Winter Haven and have driven by Waverly Growers Cooperative countless times when traveling around Polk County. But I never knew that at one time there was a formal garden and picnic grounds adjacent to the Waverly Welcome House. Founded in 1914 by a group of local growers led by Charles Hillery Walker …
European Union (EU) mandarin production for 2020-21 is forecast to rise 10 percent from the previous year, to 3.1 million metric tons (MMT). The U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reported this figure. The higher production is mainly the result of expected increases in major mandarin-producing nations Spain and Italy. Spain’s production is forecast to rise strongly to …
The Citrus Research and Development Foundation (CRDF) directors recently ratified the rootstock selections for the planned rootstock field trials and discussed the organization’s involvement in future research, CRDF Chief Operating Officer Rick Dantzler reported. The board ratified 10 rootstock selections for the new field trials, overseen by CRDF’s Select Committee on Plant Improvement. According to Dantzler, the field trials will evaluate …
Last year, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientists offered Florida citrus growers soil and leaf testing along with tailored quarterly nutrition counseling in an effort to improve tree health. The Citrus Nutrient Management Program, more commonly known as the nutrition box program, has successfully supported 75 growers from 17 counties across the state. Michael Rogers, …
By Lauren M. Diepenbrock While there are many species of ants in Florida, the invasive fire ant (Solenopsis invicta) is the one most people are familiar with. These ants can be pests in agriculture, landscapes and structures. The pest’s ability to use a variety of habitats and resources makes it challenging to manage. In citrus groves, fire ants can be …
While everyone strives to protect themselves from coronavirus disease, growers have an additional concern: protecting their trees from citrus disease. While HLB is of course the most damaging disease of citrus, there are other diseases that should not be overlooked. Disease management is the theme of the February 2021 issue of Citrus Industry magazine. University of Florida Institute of Food …
By Jeb Fields (Editor’s Note: A previous Citrus Industry article described a Soilless Substrate Science project led by Jeb Fields, assistant professor and Extension specialist at the Louisiana State University Agricultural Center. The article noted that citrus growers are beginning to explore the potential of soilless culture. This is an update to that article.) Initially we had envisioned a physical …
Proper irrigation management is key to optimize water use and increase crop yield. Water is a limiting factor in Florida citrus production during most of the year due to extremely sandy soils with low water-holding capacity and non-uniform distribution of rainfall. Soil moisture sensor systems may provide the most reliable data for effective citrus irrigation scheduling under these conditions. Rad …
European Union (EU) orange juice (OJ) production is forecast to climb almost 8 percent in 2020-21 compared to the previous year, to 87,987 metric tons, the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reported. The forecast is in line with the expected growth in the volume of European oranges destined for processing this season, especially from Spain and Italy. …
