Growers gathered in Avon Park for the annual Florida Citrus Growers’ Institute at South Florida Community College in early April. Scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) presented updates on their work and the latest efforts to help in the fight against HLB. New this year, the scientists also hosted learning stations to further …
IPCs: To Tie or Not to Tie?
By Fernando Alferez and Osbaldo Vasquez As individual protective covers (IPCs) are being adopted as a standard management practice to protect newly planted citrus trees from psyllid infestation, it has become apparent that one of the main effects of this tool is improved tree growth. Trees under IPCs grow larger with thicker canopies. This is probably the result of healthier …
Optimizing Weed Management in Citrus
Weeds can be a menace in Florida citrus. The state is home to diverse weed species and is the perfect environment for weeds to grow. Ramdas Kanissery, a weed scientist at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center, discusses weed management challenges in the March All In For Citrus podcast. …
Consumer Perceptions of Citrus Biotechnology Are Critical
Scientists see genetic editing — and in particular CRISPR technology — as a potential way to rescue Florida citrus from HLB disease, but consumer perceptions of the technology are key. The University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Bachir Kassas is working to assess consumer acceptance of biotechnology. Kassas is an assistant professor in the UF/IFAS Department …
Options for Dooryard Citrus Trees
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 …
Combine Proven Horticultural Practices to Combat HLB
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) …
Separating HLB-Affected and Healthy Fruit
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 …
Scout to Stay Ahead of Pest Populations
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. …
Digging Into Methods to Boost Citrus Soil Health
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 …
Citrus Health Forum Brings Together Growers and Researchers
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. …
Recovering Unprotected HLB-Infected Young Trees
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 …
All In for Citrus Podcast, March 2025
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 …
Integrated Pest Management Needed for Sting Nematode
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 …
Chilli Thrips Management in Florida
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 …
Pre-emergent Herbicides Preferred for Weed Management
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 …
Reduce Fruit Drop From Citrus Canker
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 to Knock Back Psyllid Populations
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 …
Will Weather Set Florida Free From the Threat of PFD?
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 …
Florida Foliar Disease Outlook for 2025
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 …
The Growth of AI-Based Agroview
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 …
