By Tripti Vashisth Fruit drop has become one of the biggest challenges for Florida citrus growers, especially in groves hit hard by HLB. On top of the disease, recent hurricanes like Ian and Milton have made the problem worse, causing fruit to drop not just during the storm but often weeks later. Other stresses — such as drought, flooding or …
In 2012, Jennifer Doudna, Emmanuelle Charpentier and their research team published a paper in the journal Science describing the CRISPR-Cas9 system as a precise gene-editing tool. It was considered a major scientific breakthrough with huge possibilities in human medicine and in agriculture. Doudna and Charpentier were awarded the Noble Peace Prize in chemistry in 2020 for their pioneering work with …

By Davie Kadyampakeni, Noor Basar, Alisheikh Atta, Muhammad Shahid, Shahid Iqbal and Alan Wright Citrus trees in Florida impacted by HLB have limited nutrient uptake largely due to limited root mass, compromised physiology and extremely sandy soil. The state’s current nutrient management guidelines were developed based on data prior to the spread of HLB, when trees had dense canopies and …
By Fernando Alferez and Osbaldo Vasquez During the last seven years, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SWFREC) in Immokalee has been performing comprehensive studies on the use of individual protective covers (IPCs). This tool is now adopted by most growers planting new citrus trees in Florida both in …
By John M. Chater Citrus tree trunk injection of antibiotics has been recently and widely used in Florida. The success of oxytetracycline (OTC) in sweet orange to mitigate huanglongbing (HLB or citrus greening) disease has been documented by the laboratory of Ute Albrecht, associate professor at the University of Florida. Some results suggest that OTC injection can improve Brix, ratio, …
The U.S. Department of Agriculture National Agricultural Statistics Service (USDA/NASS) released its last citrus crop forecast update of the 2024-25 season on July 11.

The antimicrobials for Florida citrus are ReMedium TI and Rectify; …
By Lamiaa Mahmoud and Manjul Dutt Utilizing tolerant rootstocks to combat HLB is a long-term management strategy that can help sustain productivity and enhance tree survival, especially when implemented alongside other HLB management approaches. Australian limes are tolerant to HLB, and their DNA can be incorporated into HLB-susceptible citrus using conventional breeding methods to enhance tolerance to HLB. Over the …
Brazil’s Fundecitrus recently released its 2025–26 Tree Inventory of the São Paulo and West-Southwest Minas Gerais Citrus Belt.
