For …
As high temperatures become more common in citrus-growing regions, researchers are searching for ways to help trees better tolerate heat. A new study suggests that two naturally occurring plant hormones — abscisic acid (ABA) and brassinosteroids (BR) — may strengthen citrus trees’ defenses against heat stress. The research was published in the journal Horticulturae by Longfei Jin, Yueting Sun, Yanmei …

Freeze protection is a vital part of university research in the cold-hardy citrus region. Growers in South Georgia, South Alabama and North Florida only have to look back to last season to see temperatures that dropped to dangerously low levels for citrus production. Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist, discussed freeze-protection measures at the …
When citrus growers think about viruses and viroids, symptoms above ground — such as tree decline, leaf issues and poor fruit production — often receive the most attention. A new study shows that what happens below the soil surface may also provide important clues about how citrus rootstocks respond to these pathogens. The study, “Root Traits Responses of Citrus Rootstocks …
By Jamie D. Burrow and Tripti Vashisth Florida citrus production continues to change, and staying up to date is vital. The Citrus & Specialty Crop Expo seminars are an opportunity for growers to hear the latest updates from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus researchers. A mix of panel discussions and presentations is scheduled to …
For years, conversations surrounding Florida citrus have often centered on challenges: HLB, hurricanes, freezes and shrinking production. But today, there is a different feeling taking hold across the industry. That renewed sense of optimism will be on full display at the Citrus & Specialty Crop Expo Aug. 12–13 in Fort Myers, where the Florida Department of Citrus (FDOC) is returning …
Researchers are studying why some citrus species appear to handle huanglongbing (HLB) better than others. Understanding these differences could help breeders develop more resilient citrus varieties and rootstocks for future production. A new study compared nine citrus species infected with HLB and identified differences in how the plants respond to the disease, including changes in nutrient levels, stress responses and …
The U.S. Department of Agriculture (USDA) on July 23 announced its intent to purchase $32.5 million of fresh citrus from American growers. USDA’s Agricultural Marketing Service, under Section 32 of the Agriculture Act of 1935, will make the purchases. The fresh citrus will be distributed to food banks and nutrition assistance programs across the country. The fresh citrus purchases will …
Heavy March rain in Texas’ citrus-production region brought both a sigh of relief and concerns, according to Texas A&M University-Kingsville Citrus Center researchers Veronica Ancona, Joel Cabrera and Madhurababu Kunta. TEXAS FLOODING “Receiving from 12 to 24 inches of rain across the region sounds great, except that it was in a short period of time, leaving areas flooded, including citrus …
A part of Georgia’s citrus crop lies in the southeastern part of the state. Aubrey Shirley, University of Georgia (UGA) Tattnall County Extension coordinator, believes that portion is continuing to grow. The main threat to that growth is citrus greening disease. “If we get greening really bad and it starts to hinder production, I think the industry is so young, …
The Citrus Industry section of the August issue of Specialty Crop Grower magazine features practical production advice, a new variety resource, citrus marketing insights and more. The section opens with a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) article explaining crop load management and alternate bearing in citrus. Fernando Alferez and Muhammad A. Shahid discuss why citrus …
Many people throw away citrus peels because they are too bitter to eat raw, but this outer layer of the fruit’s skin is a rich source of many sought-after beneficial compounds. The peel is in demand for companies seeking to use those compounds for health and pharmaceutical products. Christina Dorado, lead scientist and chemist at the U.S. Department of Agriculture …
The U.S. Department of Agriculture Animal and Plant Health Inspection Service and the California Department of Food and Agriculture (CDFA) confirmed the positive identification of citrus yellow vein clearing virus (CYVCV) in a residential citrus tree in the Lodi area of San Joaquin County. The plant sample was confirmed positive for CYVCV on July 7 following a routine multi-pest survey …
Shannon Shepp, Florida Department of Citrus executive director, recently discussed the renewed sense of optimism being felt in the Florida citrus industry due to recent positive developments. INCREASED CITRUS PRODUCTION One of the reasons for optimism is the U.S. Department of Agriculture’s final citrus forecast for the 2025–26 season.

In Florida, the soilborne phytophthora pathogens — primarily Phytophthora nicotianae and Phytophthora palmivora — are the leading causes of root rot, crown rot and foot rot. Two University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers recently wrote about phytophthora management in cold-hardy citrus. The authors are Assistant Professor and Extension Specialist Muhammad Shahid and postdoc Carlos Aucique-Perez, …
For the past several years, John Chater, University of Florida Institute of Food and Agricultural Sciences assistant professor of horticultural sciences, has been charged with acting as a conduit between citrus breeders and growers seeking information on new varieties and rootstocks to plant.
