From the Director 

Dear Friends,

I hope that you did not suffer serious crop damage over the recent high winds and cold temperatures Florida experienced recently. The UF/IFAS Extension citrus agents are always available to provide information to help you during these times.  I also encourage you to use the FAWN weather service as you plan for any weather-related grove management plan.

FAWN stands for Florida Automated Weather Network and provides accurate and timely rural weather information from a number of locations throughout the state at 15-minute intervals. FAWN provides data on air and soil temperatures, rainfall, dewpoint, relative humidity, windspeed, wind direction, and radiation.

This month is also a critical time for UF/IFAS funding and the state budget. IFAS has a number of budget requests that, if supported, will help citrus growers. In addition to the annual support of IFAS research, teaching, and Extension operations, this year IFAS is requesting financial support for nutrient application rate research (BMPs). IFAS citrus programs will be at the state capital on Gator Day, February 15, sharing fresh fruit and juice along with updates on our research projects and the impacts that they have for Florida growers.

Thank you for your continued support of our state funding which we need to serve you better,


Michael E. Rogers

Citrus Irrigation and Nutrient Management Workshop Planned for February 8


Register now! 

Recent research has shown Integrated nutrient management and crop protection strategies appear to improve root health, canopy size, juice quality and fruit yield in bearing orange trees. In young orange and mandarin trees, elevated micronutrients improve biomass and nutrient accumulation. Other research has shown the optimal times for applying nutrients based on tree demand. Join us for this informative workshop to learn about optimal irrigation scheduling and fertilization timing strategies and irrigation/fertilizer application amounts for both young and mature trees. This program is designed for commercial citrus growers and irrigation/fertilizer companies/vendors.

It’s tough to be a citrus grower in Florida right now. In the January All In For Citrus podcast episode, Michael Rogers discusses the challenging environment for growers. Below-average prices and low yields are among the major obstacles.

However, the UF/IFAS citrus researchers and Extension agents continue to work hard on behalf of growers, looking for tools they can use now to stay afloat. Rogers, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center director, notes several events in February to get important information out to growers. He also discusses the search for two new positions on the team to further help producers.

UF/IFAS citrus horticulturist Fernando Alferez joins the podcast from the Southwest Florida Research and Education Center (SWFREC) to provide an update on individual protective covers, which researchers are testing on young citrus. He and his team just concluded a multi-year trial on the system and saw both an increase in quality and yield. In addition, Alferez details results of some in-season treatments of relatively inexpensive products that are showing less fruit drop in Hamlin groves.

Reducing fruit drop is also something Ute Albrecht, a UF/IFAS plant physiologist at the SWFREC, is seeing in her trunk-injection research. Albrecht joins the podcast episode to share findings from a multi-year study in which a single injection reduced fruit drop dramatically. She talks about the challenges of the delivery system and new technology that may make it a practical option for growers. Albrecht reminds growers that trunk injection is still being studied and not a recommendation from advisors.

The All In For Citrus podcast is a joint project of UF/IFAS and AgNet Media. Listen to the January episode here.
