When Nian Wang pieces together sequences of genes, he hopes to make citrus varieties that are more tolerant to the deadly disease known as citrus greening, which has devastated a multibillion-dollar-a-year industry in Florida. Wang, a professor of microbiology and cell science with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), will help an investigation in which …
The U.S. Department of Agriculture released the January and February citrus crop forecasts on Feb. 8. January’s forecast had been delayed due to the government shutdown. JANUARYJanuary’s forecast showed a decrease in Florida grapefruit, tangelo and tangerine production compared to December. Grapefruit fell from 6.4 million boxes to 6.2 million boxes. Tangerines and tangelos dropped from 1.2 million boxes to …
Commercial citrus growers will soon see a new seedless mandarin variety that stays on the tree longer, two traits farmers seek, say University of Florida scientists. Marathon, an early season mandarin, is also easy to peel and tastes good, said Fred Gmitter, a professor of breeding and genetics at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). …
Florida is starting to distribute federal disaster-relief money that was approved last year to help the citrus industry after Hurricane Irma caused massive damage to groves. Jared Moskowitz, director of the Florida Division of Emergency Management, said Wednesday that the state recently awarded $14 million from a $343 million federal block grant for the industry and continues to process and …
Results show promise for organic groves, but more research is needed. Since it was first discovered in the United States in 2005, the bacterial disease known as citrus greening, or Huanglongbing, has devastated millions of acres of citrus crops throughout this country and abroad, ravaging citrus groves in Asia, Africa and South America. Citrus greening has impacted conventional and organic …
U.S. Sen. Marco Rubio implored Florida’s new governor Tuesday to start spreading disaster-relief money approved nearly a year ago to address massive citrus-industry damage from Hurricane Irma in 2017. Rubio said in a letter to Gov. Ron DeSantis that money in a $343 million block grant needs to be disbursed to citrus growers. Rubio said the federal government shutdown has …
When the next frost threatens Florida’s crops, growers will do their best to make sure your favorite foods are protected from the potentially crippling chill, say University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) experts. For example, citrus growers use wind machines and microsprinklers to ensure freezing temperatures don’t ruin the fruit, said Chris Oswalt, a multi-county citrus …
A new report from economists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Economic Impact Analysis Program (EIAP) showed higher prices offset production declines during Florida’s 2016-17 citrus growing season, and the industry’s overall economic contributions changed little from 2015-16. Titled, “Economic Contributions of the Florida Citrus Industry in 2016-17,” the report was formally presented to …
An agricultural engineer whose current research projects include the simulation of agricultural management impacts on water quantity and quality in the upper Floridan aquifer has joined the University of Florida’s Indian River Research and Education Center (IRREC). Sandra Guzmán will lead the center’s irrigation and hydrology program. Guzmán started her position as an assistant professor of agricultural and biological engineering …
Citrus growers can learn more about managing Asian citrus psyllids and other pests in a workshop Jan. 8 at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC). The psyllid can transmit the bacteria associated with greening disease to citrus trees and has already caused severe damage to Florida’s multi-billion-dollar-a-year citrus industry. …
New research data are coming from trials of citrus rootstocks, scions and combinations of the two that University of Florida scientists hope will broaden the options of greening-tolerant citrus varieties available to commercial growers. Michael Rogers, director of the Citrus Research and Education Center (CREC), part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), said scientists …
The U.S. Department of Agriculture has released three new citrus rootstocks that are available for unrestricted public use. The rootstocks are US SuperSour 1, US SuperSour 2 and US SuperSour 3. A new publication provides summary information about the new releases.

The U.S. Department of Agriculture’s 2018-2019 Florida all-orange forecast for December is 77 million boxes, unchanged from the November forecast. If realized, this forecast will be 71 percent more than last season’s final production. The forecast consists of 32 million boxes of the non-Valencia oranges (early, midseason and Navel varieties) and 45 million boxes of Valencia oranges. Current fruit size …
Three distinguished leaders will be inducted into the Florida Citrus Hall of Fame at the 57th Citrus Celebration Luncheon at 11:30 a.m. on March 8 at Florida Southern College in Lakeland. Tim Hurner of Sebring, Richard J. Kinney (deceased), formerly of Lakeland, and Peter McClure of Port Saint Lucie will be honored at the luncheon. Hurner Tim Hurner is a fourth-generation Florida …
This year’s Citrus Nutrition Day — at which growers will learn the latest data about growing the fruit, from the soil up through the plants — is expanding to include tours of field trials. After a morning of updates from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, participants may tour field sites at the Peace River …
Florida citrus growers have begun taking notice of kaolin clay, a powdery white compound, because it can cause Asian citrus psyllids (ACP) to “not take notice” of their groves. Long used to protect other fruit and vegetable crops, kaolin can also conceal citrus trees from hungry psyllids by confusing their visual sensory system, said Michael Rogers, director of the Citrus …
Florida citrus growers who plan to establish new groves might want to consider high-density planting, according to experts with the Citrus Research and Education Center (CREC) in Lake Alfred, part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Wider spacing between trees and rows was common decades ago but, with yields down and input costs up, …
On Dec. 4 at the Citrus Research and Education Center (CREC), citrus growers can see if they want to grow the latest varieties from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) breeders and then learn more about commercializing crops. In the morning, industry members can sample the latest citrus varieties from UF/IFAS breeders. “These are new varieties …
The U.S. Department of Agriculture (USDA) released its second citrus crop forecast for the 2018–19 season, projecting 77 million boxes of oranges and 84.6 million boxes of citrus in total. Compared to the October 2018 USDA forecast, this estimate represents a 3 percent decrease in orange production and a 4 percent decrease in grapefruit production. However, the overall production remains …
A new University of Florida-developed forecasting system could help citrus growers control postbloom fruit drop this winter, despite the predicted El Niño weather pattern that’s expected to bring more rain and moderate temperatures. With an El Niño, forecasters expect above-average rain this winter and early spring. Increased rain improves the chances of fungal spores splashing from flower to flower in …
