Irrigation Problem Prevention
By Ajia Paolillo To keep your irrigation system running efficiently, it is important to perform routine maintenance throughout the year. There are many types of issues that can affect your irrigation system, causing it to run poorly. Poly tubing and emitters can become clogged. Emitters can be blocked by weeds or broken through normal wear and tear. When these issues …
Sequencing Brings HLB Resistance Closer
University of Florida (UF) scientists achieved a major milestone in their quest to develop an HLB-resistant tree by sequencing the genome of a fruit plant that’s a close cousin to citrus trees. HLB is also known as greening disease. UF Institute of Food and Agricultural Sciences researchers sequenced the genome from trifoliate orange, in collaboration with scientists from the University …
Understanding the Fate and Persistence of Herbicides in Soils
By Ramdas Kanissery, Rachel Fenn, Biwek Gairhe and Davie Kadyampakeni Chemical weed control, using herbicides to manage weeds, is an important production practice in citrus groves. Herbicides applied in groves can end up in the soils from direct spray hits, indirect or non-target spray movement (also known as drifts) or release from the dead weeds and vegetation. In soil, the …
Indian River Variety Trial Attracts Visitors
Forty-nine growers and others participated in a self-guided, drive-through tour of the Millennium Block variety performance trial at the Indian River Research and Education Center (IRREC) on Oct. 9. “Several growers highlighted trees are off to a good start, and despite the fact they’re young, they could see clear differences,” said host and IRREC researcher Rhuanito “Johnny” Ferrarezi. Ferrarezi works …
Prospects for the 2020–21 Growing Season
Marisa Zansler, Florida Department of Citrus director of economic and market research, gave an update on fresh citrus prospects for the 2020–21 growing season during the recent virtual citrus Packinghouse Day meeting. Florida fresh citrus movement increased during the 2019–20 season, which was largely attributed to increased production, Zansler said. In addition to increased production, COVID-19 concerns served to move …
Maintaining Orange Juice Momentum
The Florida Department of Citrus (FDOC) normally launches minimal programs during the first quarter of the fiscal year and instead focuses on strategic planning. This year, though, in order to continue to build upon the momentum of 2019-20, the FDOC and its advertising agency, Edible, launched a robust campaign to drive sales of 100 percent orange juice (OJ) at retail. …
Is Parson Brown the Better Early Orange?
The old Parson Brown sweet orange variety is showing some characteristics that could make it more attractive than Hamlin, which has long been Florida’s leading early-season orange. “Observations made in commercial blocks in Polk and neighboring counties illustrate an improved canopy density, improved mature fruit retention and higher yields in the early-maturing Parson Brown sweet orange when compared to adjacent …
Commissioner Fried on Citrus Forecast
Florida Agriculture Commissioner Nikki Fried offered the following statement on the initial citrus crop forecast for the 2020-21 season released today by the U.S. Department of Agriculture (USDA): “When Americans think of wellness and health, their thoughts turn to Florida orange juice and fresh citrus, especially during these unprecedented times. Despite the challenges that Florida’s citrus growers have faced as a …

Soilless Substrate Science Seeks Citrus Industry Input
Citrus growers are beginning to explore the potential of soilless culture. Ample opportunities exist for ever-evolving systems offering improved yield while overcoming a diminishing availability of soil fumigants and increased pest pressure. There is a need for flexibility in a constantly changing world of new production methods and regulations. Soilless culture provides an unprecedented opportunity to rethink how tree fruit …
Get the Science on Climate Change
“Our climate is changing and, with that, comes more extreme events,” said Ashley Smyth, an assistant professor of soil and water science at the Tropical Research and Education Center in Homestead. The center is part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). “Just look at the most recent hurricanes. As they cross the Gulf, they …
First Crop Forecast of the Season Is Oct. 9
Industry members will have several ways to hear the first official U.S. citrus crop forecast of the 2020–21 season. Agricultural Statistics Administrator Bill Curtis of the Florida Department of Agriculture and Consumer Services will deliver the forecast at 12:00 noon Eastern Daylight Time on Friday, Oct. 9.

HLB Research Featured on Website
By Madison Sankovitz, Barbara Alonso, Monique Rivera, Lukasz Stelinski, Sara García-Figuera, Peggy G. Lemaux and Beth Grafton-Cardwell The bacterial disease huanglongbing (HLB) is a devastating disease and has caused massive losses to the U.S. citrus industry. The disease vector, the Asian citrus psyllid, is currently in all U.S. citrus-producing states, and the disease continues to exert a severe impact on …
Progress Toward HLB-Tolerant Citrus
Largely due to the advent of huanglongbing (HLB) disease, Florida orange production has declined by over 70 percent in the last 10 years. According to experts, if the trend is not reversed, processing plants will not have enough fruit to maintain production and profitability, ultimately causing shutdowns. Currently, Florida law requires that orange juice be comprised of at least 90 …
Black Spot and Production Guide Updates
Megan Dewdney recently provided information about positive results from fungicide trials for citrus black spot, as well changes to the new Citrus Production Guide. Dewdney is a plant pathologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), working at the Citrus Research and Education Center. Dewdney conducted the fungicide trials for black spot in a 20-year-old …
Florida Crop Workers at Risk
As laborers return to the fields this fall in Florida, both unauthorized crop workers and H-2A workers are vulnerable to the coronavirus. According to a new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study, an estimated 75 percent of Florida crop workers have at least one underlying health issue that puts them at risk of developing COVID-19 …
Orange Juice Import Impacts
Economist Tom Spreen discussed the impact of imports in the United States orange juice (OJ) market at the Sept. 16 Florida Citrus Commission meeting. Spreen is retired from the University of Florida Institute of Food and Agricultural Sciences. Spreen’s analysis began with increased imports in 2017 after Hurricane Irma struck Florida.
