Texas A&M University citrus scientists who developed a successful planting method to combat diaprepes root weevil found that the method also offers numerous other benefits. In 2013, researchers Mamoudou Setamou and Olufemi Alabi were looking for an effective non-chemical method to physically block the circular foliage-to-underground lifecycle of diaprepes. The pest was attacking citrus roots and killing trees. Their solution …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is the new home for Breeding Insight, a federally funded program supporting public plant breeding efforts.

Control of HLB-spreading Asian citrus psyllids (ACP) can be enhanced with dormant winter sprays and a focus on spraying grove perimeters, according to Citrus & Specialty Crop Expo presenter Jawwad Qureshi. Qureshi is an associate professor of entomology at the University of Florida Institute of Food and Agricultural Sciences Southwest Florida Research and Education Center. DORMANT SPRAYS In making the …
By Lauren Diepenbrock Unlike northern regions, fall in Florida is not generally a time when insect, mite and other invertebrate pest populations decline rapidly. In Florida citrus, we generally see the opposite of this trend. In the hot, dry end of summer and early fall, mite populations often soar, requiring management to prevent excessive damage to fruit. (See The Florida …
Blood oranges may be an enticing fruit to grow for cold-hardy citrus producers in North Florida, South Georgia and South Alabama. Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), highlighted his blood orange research during the Cold-Hardy Citrus Field Day and Workshop at the North Florida Research and Education Center …
By Manjul Dutt Editor’s Note: This is the first in a series of two articles on plant improvement. Next month will feature the timeline for CRISPR-developed trees. Traditional methods for improving citrus, such as crossbreeding different varieties, can be time-consuming due to the creation of a random mix of genes from both parents through a process called genetic introgression, leading …
Not far from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) in Lake Alfred, Jason Griffin owns and operates a commercial citrus grove. While commercial in nature, the grove also has become a working experiment for the CREC citrus breeders. Griffin has worked closely with UF/IFAS citrus breeder Jude Grosser to …

At the recent Citrus & Specialty Crop Expo, Ozgur Batuman reminded seminar attendees there is no silver bullet for HLB management. Instead, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher proposes that growers integrate several tools for the management of HLB. These tools include a variety of ways to control HLB-spreading psyllids; oxytetracycline (OTC) trunk injection; …
The 2025–26 California forecast for Tango and W. Murcott Afourer mandarin varieties, released Sept. 12, is 33 million 40-pound cartons. The forecast came from the California Department of Food and Agriculture (CDFA), cooperating with the U.S. Department of Agriculture National Agricultural Statistics Service (USDA NASS). The forecast is based on the results of the 2025–26 Mandarin Objective Measurement Survey, which …
Spain’s Ministry of Agriculture, Fisheries and Food has forecast national citrus production of 5.44 million tons for the 2025–26 season, which began Sept. 1. That’s 10.7% lower than last season’s production and the lowest production level in the last 16 years. The decline is mainly due to: Oranges, small citrus fruit and lemons are expected to see significant declines, while …
A recent study reveals that consuming 100% fruit juice is a marker for healthier diet choices and does not displace whole fruit consumption. The study, published in Nutrients on Aug. 21, explored the consumption patterns of 100% fruit juice and diluted juice with the goal of better understanding its relationship to diet quality. Population groups in the study included consideration …
Breeding efforts to develop citrus trees resistant to HLB are well underway. But how long does the process take before trees are available to growers? Manjul Dutt, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, addresses this question and more in the Citrus Industry section of the October issue of Specialty Crop Grower magazine. His article …
The University of Georgia (UGA) has disease labs and clinics to help citrus producers determine what diseases are impacting their trees. Jonathan Oliver, UGA assistant professor and small fruits pathologist, highlights the diagnostic facilities that growers can take advantage of. “We have a lab in Tifton, the Plant Disease Clinic, that can accept samples from commercial citrus,” Oliver said. “We …
