Growers received welcomed news in June when trunk-injection therapy of oxytetracycline (OTC) was cleared for continued applications next season. Some growers have said the treatment has helped save groves from loss due to HLB. Ute Albrecht, University of Florida Institute of Food and Agricultural Sciences associate professor, has been one of the lead researchers on OTC applications and its effectiveness. …
By Jamie D. Burrow, Tripti Vashisth and Michael E. Rogers In the early days of huanglongbing (HLB), the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Team realized it needed to bring its HLB content together on a single website to make it more accessible. The website has become outdated, and much more is available today for …
Compost-amended plots (left) had more weeds than those with no compost. A new study published in Scientific Reports examines whether repeated compost applications could improve the health and productivity of young citrus trees growing under endemic huanglongbing (HLB) conditions in Florida. Gabriel Pugina, Caroline Tardivo, Brittney Monus, Emma Dawson, Sarah Strauss and Ute Albrecht of the University of Florida Institute …
The next harvest season may still be months away for Florida citrus growers, but management remains a weekly duty. That involves a plethora of chores for grove owners this summer, says Matt Smith, University of Florida Institute of Food and Agricultural Sciences Extension agent for Lake and Orange counties. “Growers definitely need to keep irrigation in mind. And of course, …
The citrus research team at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) generates a lot of information from the trials and experiments they conduct each year. That information can be a valuable resource to growers who are seeking production guidance for their groves. In the June episode of the All In For Citrus podcast, Michael Rogers, …
By Ute Albrecht, Larissa Nunes and Igor Silva Trunk injection of oxytetracycline (OTC) requires drilling a hole into the trunk and injecting a foreign substance into the tree. Not only does the physical damage from drilling cause injury, but the application of chemicals can exacerbate both the external and internal damage. BARK CRACKING Externally, aside from the drill hole, bark …
By Jamie Burrow and Tripti Vashisth If you haven’t had a chance yet, take a few minutes to explore the new 2026 University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Variety Guide. You’ll find it beginning on page 21 of the April 2026 issue of the UF/IFAS Citrus Magazine. WHAT IT INCLUDES This guide is designed to …
By Ute Albrecht, Gabriel Pugina and Larissa Nunes According to a recent industry survey, 64% of Florida citrus growers have injected their trees for three consecutive years with oxytetracycline (OTC). This article reports the results from three research trials conducted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Plant Physiology Team at the Southwest Florida Research …
Southeastern residents increasingly support stronger protections against agricultural disease threats as concerns grow over food-system disruptions, say researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Findings from an August 2025 public interest survey distributed to 1,035 Southeast residents reflect growing public concern about how agricultural threats can affect food systems, public health and disaster preparedness. …
By Tripti Vashisth, Taylor Livingston, Meryam Manzoor and Johann Hiller Citrus fruit quality and yield remain major concerns for sweet orange growers in the huanglongbing (HLB) era. These outcomes largely depend on the tree’s ability to support developing fruit throughout the growing season. Leaf area and canopy density are positively correlated with carbohydrate production and allocation to fruit, directly influencing …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Steven Hall is the right guy to run a single state-supported citrus research organization. He is an agriculturalist as well as an administrator and attorney. He is a sixth-generation Florida farmer who leads his family farming operation in Jackson County. Since Hall was appointed executive director of the Citrus Research and Field Trial (CRAFT) …
Florida’s soils present unique challenges for growers. The soils vary widely from nutrient-poor sandy to highly organic soils, depending on location. These conditions make it difficult to sustainably manage agriculture in a way that supports food production, environmental health and a strong economy. To address these challenges, University of Florida (UF) researchers are leading a four-year study supported by a $749,999 …
By Lauren Fessler Mathews, Ana Redondo and Ozgur Batuman Citrus canker continues to impact Florida citrus, increasing premature fruit drop and decreasing yield and fruit quality. While copper sprays have long been relied upon to control this disease, concerns about environmental impact and possible resistance development have led to efforts to find sustainable alternatives. Previous studies have shown that plant …
After significant drought in many parts of Florida, some much-needed rainfall began in May as the rainy season approaches. That seasonal transition, from a grove management perspective, is the focus of the May episode of the All In For Citrus podcast. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education …
By Lukasz Stelinski For many Florida citrus growers, pest management has become closely tied to Asian citrus psyllid control. That is understandable. The psyllid vectors the bacterium associated with citrus greening, and long-term disease pressure has pushed many operations toward frequent insecticide use. But frequent spraying comes at a cost. The more often the same chemistry is used, the faster …
By Ramdas Kanissery When the summer heat rolls in and the rain gets spotty, growers tend to shift their focus to irrigation, nutrition and HLB management. Weed control often gets pushed to the back burner. But here’s the thing: Heat and dry spells do not stop weeds. They change them, and those changes can make your weed management program a …
Have you heard of the term PULA yet? If not and you apply pesticides on your farm, now is the time to get up to speed on pesticide use limitation areas (PULAs). This topic was covered during the Florida Citrus Growers’ Institute, held at South Florida College in Avon Park in April. Matt Smith, University of Florida Institute of Food …
Florida Citrus Mutual hosted its spring informational meeting for growers at Golden Ridge Groves in Alturas on May 13. Golden Ridge Groves is growing fresh fruit in citrus under protective screen and recently added you-pick and agritourism options for the public. Steven Hall, executive director of the Citrus Research and Field Trial (CRAFT) Foundation, gave an update and recounted the …
By Tripti Vashisth and Taylor Livingston Florida is currently experiencing one of the most severe droughts in the past 25 years, putting HLB-affected trees under intense water stress. With Florida’s well-draining sandy soils and increased water demand in HLB-affected trees, growers are in a difficult position trying to maintain adequate tree hydration. Soil amendments, such as biochar and compost, can …
By Megan Dewdney Algal spot is rarely a top concern for growers until it seems to be suddenly everywhere. Is the disease a major concern or a nuisance? It depends. If the disease is only in a few locations, then the management goal is making sure that the disease is not spreading too widely. If many trees are affected, the …
