Citrus trees used to be a common site around Florida homes, but diseases like canker and greening have diminished residents’ ability to enjoy these iconic trees. Despite the challenges, people from Florida and across the country contact citrus nurseries this time of year, seeking to purchase trees for their yards and/or homes. It’s a passion, say nursery owners and University …
By Tripti Vashisth and Prudhvi Vulchi To mitigate the effects of huanglongbing (HLB) on tree health and productivity, growers are encouraged to adopt proven horticultural practices. Based on recent field trials at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), one effective approach combines frequent irrigation (FI), plant growth regulators (PGRs) …
Scientists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and the U.S. Department of Agriculture Agricultural Research Service (USDA/ARS) recently wrote about efforts to identify HLB-affected versus healthy citrus fruit. UF/IFAS scientists are Mark Ritenour, Ketan Shende and Thomas Burks. Michelle Heck is with the USDA/ARS. A slightly edited version of their article follows: Most citrus …
It is much better for Florida citrus growers to be proactive than reactive when managing pest populations. Scouting and monitoring citrus groves is crucial for growers who hope to thwart off impacts from insects like the Asian citrus psyllid (ACP). If growers are not successful, they will be behind the eight ball in minimizing the impact of these annual pests. …
By Sarah Strauss, Emma Dawson, Gabriel Pugina, Ute Albrecht, Jonas Pereira de Souza Junior and Davie Kadyampakeni While soil health has always been considered critical for Florida citrus production, it has increased in importance with the endemic presence of citrus greening (HLB). Soil health is similar to the concepts of soil quality or soil fertility but with an additional focus …
By Maegan Beatty Earlier this month, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) hosted the 2025 Citrus Health Forum. Growers gathered to learn about citrus production and hear regional citrus updates. Muhammad Shahid, UF/IFAS assistant professor, presented information on optimizing nitrogen fertilization to enhance the quality of satsuma mandarins. …
By Fernando Alferez and Saoussen Ben Abdallah Individual protective covers (IPCs) are now being increasingly adopted in Florida to protect newly planted citrus trees from psyllid colonization. The risk of new citrus plantings becoming infected with HLB is especially high, as young trees flush more frequently and attract more psyllids. However, the adoption of IPCs does not occur in all …
With spring comes a number of citrus events. One of those was the Florida Citrus Show held on March 13 in Fort Pierce. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, joins the March All In For Citrus podcast to discuss highlights of Florida Citrus Show. He also …
By Maegan Beatty During the recent citrus insect management workshop at the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center, Larry Duncan, a nematology professor, discussed the sting nematode. First recognized in the 1980s as a pest of young citrus trees, the sting nematode has adapted to coarse, sandy soils. The pest feeds at …
By Maegan Beatty Last month, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a citrus insect workshop that covered almost 10 different pests that pose a threat for Florida citrus. Lance Osborne, professor and researcher at the Mid-Florida Research and Education Center, presented research on chilli thrips. Chilli thrips (Scirtothrips dorsalis) can live in over 150 …
It is best for citrus growers to implement a proactive approach to weed management. Being reactive puts producers behind the eight ball with regards to controlling certain weeds in their groves. That’s why Ramdas Kanissery, weed scientist and associate professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), is preaching the importance of pre-emergent herbicides. They …
By Megan Dewdney Citrus canker can contribute significantly to the loss of fruit prior to harvest. As bloom begins in Florida, it is time to finalize management plans for foliar diseases. For many growers, very aggressive canker management programs are no longer a possibility, however, some management is important. Citrus canker susceptibility of young fruitlets usually starts at the end …
Now is the time for Florida citrus growers to implement management tactics to control the Asian citrus psyllid (ACP), the insect that vectors citrus greening, also known as huanglongbing (HLB). ACPs are currently in low populations across Florida’s citrus-producing region. That means growers should act now to protect their crop from the insect’s impact, says Chris Oswalt, University of Florida …
By Megan Dewdney Despite being in a transition from a La Niña to a neutral El Niño Southern Oscillation phase, Florida has not had warmer than average temperatures in the last two weeks from March 3. Looking at historical trends, temperatures for the last two weeks of February were in the normal range for this time of year. When looking …
By Megan Dewdney As I write this article in January 2025, the world is a chilly place, and it is hard to imagine warm and wet weather in Florida. The predicted weather pattern from now until flowering is moving from La Niña toward neutral. This is predicted to bring above-average spring temperatures with reduced rainfall. This is a hopeful sign …
A few weeks after Yiannis Ampatzidis started working at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) in 2017, Hurricane Irma wreaked havoc on Florida citrus groves. Growers needed to count their trees with precision to get crop insurance, but it was a laborious, time-intensive task. Ampatzidis, associate professor of agricultural and biological engineering at the Southwest …
Morgan McKenna Porter, who grew up in a Florida citrus family, remembers having orange fights as a youth with her cousin, Riley. When she started classes at the University of Florida in 2010, she knew she wanted to major in agriculture. Porter took classes in the UF/IFAS College of Agricultural and Life Sciences and graduated in 2014 with a bachelor’s degree …
Ute Albrecht, associate professor of plant physiology with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), joined the February All In For Citrus podcast to discuss the latest learnings in optimizing trunk injections of oxytetracycline (OTC) aimed at reducing HLB in trees. She shared what has been discovered over the past few years in terms of application …
By Ozgur Batuman and Amit Levy Citrus yellow vein clearing virus (CYVCV) was first reported on lemon and sour orange trees in Pakistan in 1988. Since then, the disease has been primarily restricted to Asian countries. However, CYVCV was more recently detected in dooryard citrus in California in 2022. While there is no indication that the virus is present in …
The Citrus Industry section in the March issue of Specialty Crop Grower magazine offers timely information citrus growers won’t want to miss. Now is the time for Florida citrus producers to begin thinking about their disease management programs for the season. Megan Dewdney, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist, offers a foliar disease outlook …
