    All In For Citrus, Episode 90 February 2026

    Florida experienced one of the most damaging freezes in more than a decade this winter. The February episode of the All In For Citrus podcast addresses the impacts the freeze had on citrus. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, notes that it will take some time for the full scale of damage to be sorted out. He adds the intensity of damage varied from location to location, but early reports are that some groves took on significant damage. Matt Smith, UF/IFAS Extension commercial crop production and food systems agent for Lake and Orange counties, shares what he is observing in terms of damage. He noted there is significant damage in the counties he serves. Smith also talks about the potential disaster relief programs that might be forthcoming and how growers can prepare to be in a good position to receive funds. A key element of this is documenting all damage that has occurred on the farm. That damage could include lost fruit, injured or dead trees, or broken equipment like irrigation pipes. Take many photos to document the damage, Smith advises. While not directly related to the freeze, Smith also discusses the recently announced Assistance for Specialty Crop Farmers Program. This U.S. Department of Agriculture bridge payment program is making a total of $1 billion available to specialty crop growers. The deadline to apply is March 13. Muhammad Shahid, UF/IFAS assistant professor at the North Florida Research and Education Center, details agronomic measures growers can take to rehabilitate freeze-damaged trees. He says a key is patience to give trees time to adjust before taking actions like fertilization and pruning. The podcast is a partnership between UF/IFAS and AgNet Media.

    All In For Citrus, Episode 89 January 2026

    In the latest 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 Center, discussed a statewide citrus workshop hosted at the Southwest Florida Research and Education Center in January. The event provided a day full of educational presentations covering a wide range of topics. Rogers noted several of the talks explained how HLB impacts citrus trees internally and how certain therapies help counteract those effects. Ute Albrecht, UF/IFAS associate professor of plant physiology, also joined the podcast to discuss her research on the use of oxytetracycline (OTC). Albrecht reported the yield results from a fairly large trial in a commercial Hamlin grove that has had three applications of OTC. The trial results reinforce the thinking that OTC has a cumulative effect over the course of several years as root systems get reestablished and tree health returns. The third-year yield data show significant yield increases in OTC-treated trees compared to controls. Davie Kadyampakeni, UF/IFAS associate professor of citrus water and nutrient management, summarized the take-home messages from his presentation at the workshop, which focused on optimizing citrus nutrition. A key point was to ensure nutrition is always available to citrus trees and in amounts that the trees can actually take up due to reduced root systems from HLB. This is even true with slow-release fertilizers. He recommended split applications throughout the year to ensure there is some overlap as one dose of slow-release fertilizer plays out. Kadyampakeni also gave a brief update on the status of new recommendations from UF/IFAS for citrus nutrition. He said there has been a slight delay in releasing the update but expects it will be coming soon.

    All In For Citrus, Episode 88 December 2025

    As 2025 winds down, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), took time to recognize Chris Oswalt during the December All In For Citrus podcast. Oswalt is retiring from his post as a citrus Extension agent, which he’s held for nearly 30 years. He served Polk and Hillsborough counties. “I quickly got connected with Chris when I first came to CREC in 2004,” Rogers said. “He was a big help to me, especially earlier in my career. He has helped get many new faculty pointed in the right direction when they come on board. He is down to earth and grounded in reality, and growers trust him because of that. We wish him well in retirement.” Rogers also took the occasion to remind growers to engage with the citrus agents in Florida because they can be a valuable resource. Find your citrus agent here. “If you’ve not had an agent out to your operation, invite them to come out,” Rogers said. “Get them involved and visiting you in the field. It will help the agents develop their programs and serve you better.” One of the citrus agents, Edwin Gutierrez, also joins the podcast to discuss ways to prepare groves for winter and potential freeze events. He covers DeSoto, Hardee and Manatee counties. Some of his key points include making sure trees are as healthy as possible going into winter because a healthy tree will withstand a freeze better. He also advises growers to check their irrigation systems regularly to ensure they are operating properly. Irrigation is the main line of defense to protect trees during a freeze. Muhammad Shahid, UF/IFAS assistant professor at the North Florida Research and Education Center, addresses winter preparations for the cold-hardy region. Freezes are far more regular occurrences in that area. Shahid discusses his research with silicon, which appears to boost citrus trees’ resistance to freezes. He also tells how a new mandarin variety, nicknamed Greenie, may have found a home in the cold-hardy region.   The podcast is partnership between UF/IFAS and AgNet Media.

    All In For Citrus, Episode 87 November 2025

    The November All In For Citrus podcast takes a trip around the globe. Faculty from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) join the show to describe citrus production in regions outside of the United States. Michael Rogers, director of the UF/IFAS Citrus Research and Education Center, gives an update on citrus in the Caribbean and how UF/IFAS scientists collaborate with colleagues in those countries to advance citrus production knowledge. The podcast also provides updates on citrus production in South America, Brazil, the Indian subcontinent, Israel, Africa and the Mediterranean. One of the key takeaway messages from the episode is that sharing knowledge with other production regions benefits all citrus growers globally. UF/IFAS scientists say that, in most cases, U.S. citrus producers can gain beneficial knowledge by following what is happening in other parts of the world. Flavia Zambon, UF/IFAS assistant professor, gives an update on citrus in her home country of Brazil. The world’s largest citrus producer has begun to feel the bite of HLB more acutely in recent years. In addition, an ongoing drought in Brazil is challenging citrus production. Tripti Vashisth, UF/IFAS associate professor, discusses citrus production on the Indian subcontinent. Interestingly, growers in that part of the world have been dealing with HLB for more than 100 years but have remained relatively productive. Vashisth said that is due in part to the region’s better soils and production practices. The podcast is a partnership between UF/IFAS and AgNet Media.

    All In For Citrus, Episode 86 October 2025

    The October All In For Citrus podcast features citrus under protective screen (CUPS). Over the past decade, the practice has grown in popularity due to its ability to exclude the Asian citrus psyllid and huanglongbing (HLB) disease. Roughly 1,500 acres of citrus are grown under screen in Florida with more acreage under development.   Lauren Diepenbrock, associate professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), addresses pest management in CUPS. While CUPS successfully keeps out the psyllid, other pests are small enough to breach the mesh netting. Those pests include chilli thrips, lebbeck mealybug and mites. Diepenbrock discusses her research on how these pests enter, survive and multiply in CUPS and the latest knowledge on managing the pests. She also provides information on strategies like introducing beneficial insects in the structures to manage the pests. Megan Dewdney, UF/IFAS associate professor of plant pathology at the CREC, joins the discussion to talk about disease management in CUPS. She says greasy spot and citrus canker have been the most problematic diseases in the system. Jerry Mixon, a CUPS grower in Central Florida, shares why he tried the CUPS approach and what his experience has been like so far. Mixon says he was impressed with the yields and very high-quality fruit CUPS can produce. He also had experience building similar structures (to exclude birds) when he and his family grew blueberries. Mixon mostly grows grapefruit in his CUPS but is evaluating other varieties in collaboration with UF/IFAS. He has also worked with Diepenbrock and Dewdney on pest and disease trials in his structures.

    All In For Citrus, Episode 85 September 2025

    Varieties and rootstocks are the topics of the September episode of the All In For Citrus podcast. Earlier this month, a field day was held in Jason Griffin’s grove near Lake Alfred, Florida. He is collaborating with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to evaluate several rootstock/scion combinations developed by UF/IFAS citrus breeders. Griffin has focused much of the trial work on the OLL variety line, which was developed by Jude Grosser, UF/IFAS professor of plant cell genetics. Both Griffin and Grosser are podcast guests this month. Grosser discusses his research developing the OLL varieties and why he believes they are a good fit for Florida growers. The OLL line grew out of his relationship with Orie Lee. Lee was a legend in citrus breeding circles and discovered an interesting tree in his research groves near Saint Cloud, Florida, where the original OLL cuttings were taken. Grosser has developed several OLL varieties that are now commercially available. Combinations like OLL-8 on UFR-4 rootstock have performed well. Grosser also recommended growers consider the Orange 14 rootstock, which has shown some tolerance to both diaprepes and HLB.   Griffin discusses his grove trials and why he selected the OLL line. Tolerance to HLB, good yield and quality are among the reasons he likes the varieties. There are several rootstock/scion combinations he highlights as favorites during the podcast. One of those is OLL-20 on a mutant X639 rootstock.  Griffin also talks about the importance of a solid production program to promote tree health and productivity. In addition to a solid fertilizer program, he is a big believer in compost and mulch to increase soil organic matter. More frequent and controlled irrigation is also an important part of his program.

    All In For Citrus, Episode 84 August 2025

    The August All In For Citrus podcast features seminar recaps from the Citrus & Specialty Crop Expo, which was held this month at the Florida State Fairgrounds in Tampa. The event included an extensive citrus educational program with more than 20 presentations. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, shares highlights from the event in this month’s podcast. Rogers discusses the citrus under protective screen (CUPS) presentation by Arnold Schumann, UF/IFAS professor of soil, water and ecosystem sciences. The presentation included details on the significant increase in acres dedicated to CUPS in Florida and the high value of CUPS-grown crops. Schumann also introduced a new AI chatbot called "CUPS Chat" to assist growers with questions about CUPS production. Rogers also talks about the Citrus Research and Field Trial (CRAFT) programs and the new cycle of funding for new plantings and therapies in existing groves. Many of the new varieties and therapies that are part of the CRAFT programs have been developed and/or evaluated through UF/IFAS research. In the podcast, John Chater, UF/IFAS assistant professor of horticultural sciences, provides descriptions of new varieties that have been added to CRAFT and are eligible for the program’s planting incentive. Sarah Strauss, UF/IFAS associate professor of soil microbiology, also joins the August episode of All In For Citrus to discuss her presentation at the Citrus & Specialty Crop Expo. Her talk focused on ways to measure the impact that cover crops and/or compost have on soil health. She said with Florida’s sandy soils, the practices take time to increase organic matter and soil health, but they do offer potential benefits.

    All In For Citrus, Episode 83 July 2025

    The July All In For Citrus podcast episode focuses on the Citrus & Specialty Crop Expo. The event is scheduled for Aug. 20–21 at the Florida State Fairgrounds in Tampa. Micheal Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, previews a new, special educational session on alternative crops. Rogers said the session will focus on bamboo, macadamia, avocado and mango production. The bulk of alternative crop presentations will focus on bamboo, which has been gaining more attention in recent years. Rogers said there are more than 1,000 acres of the crop planted in Florida, and some processing infrastructure is falling into place. Bamboo has food, wood and other use functions and is in high demand. He said the goal of the bamboo presentations is to set realistic expectations about the cost of establishing the crop, growing it and its market potential. Tripti Vashisth, UF/IFAS associate professor of citrus horticulture, joins the podcast to provide details on the citrus seminars, which include 21 presentations on HLB management and other current topics. She said the primary focus of the presentations will be to provide information that growers can use in their groves right now. Jamie Burrow, UF/IFAS Extension program manager, talks about the UF/IFAS citrus research booth that will be on the trade show floor. The booth is one of the largest exhibits and is always a highlight for attendees. Burrow said several key research scientists will be available throughout the event at the booth so growers can have one-on-one interactions with the experts. Attendees can also pick up educational materials in the booth like the new edition of the Florida Citrus Production Guide. And there’s plenty of swag like pens, notepads and other freebies for the taking in the booth. Don’t miss the latest All In For Citrus episode.
