Florida Citrus Mutual Executive Vice President and Chief Executive Officer Matt Joyner’s optimism about the industry’s future comes on the heels of a major citrus grower stepping out of production. Alico’s departure from the citrus industry earlier this year was a body blow to the industry, according to one industry expert. Joyner feels similarly but also believes there are extenuating …
By Steven Hall The Citrus Research and Field Trial (CRAFT) Foundation received applications in Cycle Six for almost 10,000 acres of New Tree Planting (NTP) proposals and applications for nearly 47,000 acres for inclusion in Cycle Three of the Existing Tree Therapies (ETT) program. WAITLIST ESTABLISHED This demand exceeded the funding available for both programs. The selected applicants have received …
The future of Florida’s citrus industry rests on short-term survival while building a future that does not include citrus greening disease. Rick Dantzler, Citrus Research and Development Foundation chief operating officer, spoke at this year’s Georgia Citrus Association annual meeting in Tifton. He emphasized that while tools like oxytetracycline (OTC) provide growers relief, its long-term effectiveness is not guaranteed. Therefore, …
It can be hard to have hope if you are a farmer in today’s agricultural climate. It can be even harder to have optimism if you are a Florida citrus grower. Yet, Matt Joyner, Florida Citrus Mutual executive vice president and chief executive officer, has hope that the industry is trending upward even amid HLB and multiple hurricanes in previous …
Rick Dantzler, Citrus Research and Development Foundation (CRDF) chief operating officer, believes there is a future for Florida’s citrus industry. His optimistic outlook is based on approaches that researchers have implemented to help growers survive in the short term, such as oxytetracycline (OTC) trunk injection, and work toward the development of an HLB-resistant tree. Dantzler shared that hope during the …
The Highlands County Citrus Growers Association hosted its annual banquet on March 6 in Sebring. The event drew a good crowd to catch up on the association’s activities. Two of the featured speakers during the event discussed alternative trunk-injection therapies to the current standard of oxytetracycline (OTC). Tanishka Aglave, a sophomore at Strawberry Crest High School, received the H. Robert …
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 …
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 …
Different formulations of zinc applied by foliar spray increase fruit yield by reducing fruit drop in Hamlin and Valencia oranges, according to horticulturist Fernando Alferez. In some cases, he said, potassium enhances the beneficial effects of zinc. Alferez is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Southwest Florida Research and Education Center …
The Florida Citrus Show is a day full of learning, fellowship and fun. The educational seminars includes presentations for all specialty crop growers. The general session tackles some of the big issues facing growers today, including ag labor, what to expect from the new Trump administration and a grower panel discussing the challenge of citrus greening. After lunch, breakout sessions …
By Tripti Vashisth and Mary Sutton HLB-affected trees have small and weak root systems. These trees often experience water and nutrient deficit. However, not all HLB-affected trees experience the same impact. Trees with severe HLB symptoms will have higher root loss and water deficit than trees with mild HLB symptoms. The water deficit exacerbates during spring, which is often the …
In the February episode of the All In For Citrus podcast, Michael Rogers provides an update on activities at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred. He said the beginning of the year is the time when current and future projects are evaluated. “The months of February and …
By Megan Dewdney Spring is the time to start thinking about foliar disease management in Florida. Depending on the type of citrus being produced and the market destination, different diseases will be important. POSTBLOOM FRUIT DROP The disease that affects all citrus, particularly oranges, is postbloom fruit drop (PFD). This disease is highly dependent on the weather during bloom. Currently, …
By Fernando Alferez and Divya Aryal Like the work being done with Hamlin sweet orange, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are studying the effect of brassinosteroids (BRs) on the internal maturation of Valencia sweet orange fruits. The conditions of the treatments are the same as in Hamlin: A treatment of 186 milliliters of BR …
The Florida Citrus State of the Industry Survey seeks input from growers on key issues affecting their groves. The survey has been conducted for many years, has tracked the trajectory of HLB and reported on production practices. While not a scientific survey, it has reflected general trends over the years. Last month, we published results on trunk-injection therapy and the …
Rick Dantzler, Citrus Research and Development Foundation (CRDF) chief operating officer, reported that the foundation’s January board of directors meeting was a productive one that resulted in the approval of several key citrus research projects. “We had a great meeting. The board approved funding to use a strain of Bacillus thuringiensis (Bt) to kill the progeny of psyllids,” Dantzler said. …
By Ramdas Kanissery Tackling herbicide tolerance in weeds is a critical aspect of effective weed control in citrus groves. It helps prevent both current and future weed management challenges. Herbicide tolerance occurs when certain weed species naturally survive and reproduce after herbicide treatment. Unlike herbicide resistance, where genetic changes allow weeds to survive and spread, herbicide tolerance doesn’t involve any …
The citrus section in the February issue of Specialty Crop Grower is coming soon. It’s full of features for growers to dive into. First up is part two of results from the Florida Citrus State of the Industry Survey. (See part one here.) Learn out what percent of growers say they are replanting and how many are participating in the …
By Meryam Manzoor, Jamie D. Burrow, Taylor Livingston and Tripti Vashisth Effective nutrient management and accurate nutritional analysis are critical for tree growth and maximum yield. Historically, nutrient management for healthy citrus trees involved annual leaf sampling from July to August, with subsequent fertilization plans based on a single nutrient analysis. Almost all commercial citrus groves in Florida are affected …
With 2024 in the rear view mirror, we asked leaders of key citrus organizations what their priorities are for this year. Here’s what they had to say. TREE OF THE FUTURE “For the last 2.5 years, our research strategy at the Citrus Research and Development Foundation has been to kill the bacteria that causes HLB — Candidatus Liberibacter asiaticus (CLas) …
