By Ramdas Kanissery and Robert Riefer Pre-emergent herbicides, also known as residual herbicides, are highly effective in the long-term suppression of weeds in citrus tree rows. These herbicides remain in the soil and prevent susceptible weeds from germinating. In order to achieve the best weed control results, pre-emergent herbicides need to stay within approximately the top 5 inches of soil, …
The effort to help huanglongbing (HLB)-impacted citrus trees has taken another step forward. A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study examined the relationship between fertilization, root health and fruit yield. Researchers focused on Valencia orange trees with HLB. Associate Professor Davie Kadyampakeni led the effort at the UF/IFAS Citrus Research and Education Center. The study, …
If you grow citrus in Florida, you’ve probably heard the term CRISPR used in discussions about gene editing to find HLB resistance. CRISPR is complicated science but holds great promise in fighting both human and plant diseases. At the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), Nian Wang, a professor of microbiology and cell science, has been …
The February issue of Citrus Industry magazine takes a look at efforts to combat HLB. Some strategies are already available for growers to implement in their groves, while others offer hope for long-term solutions. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently launched a new Crop Transformation Center. The goal of the center is to use …
The quest for long-term solutions to HLB is well underway. Technology like CRISPR is being developed to introduce tolerance or resistance to HLB. Conventional breeding also is seeking rootstocks and varieties that can resist the disease. In the meantime, growers are reminded to utilize available tools that help trees remain productive in an HLB environment. During the August Citrus & …
By Lauren Diepenbrock Insect and mite management is a year-round challenge in Florida citrus. With the warm climate, pests are at the ready as soon as plant resources are available to them. With knowledge of insect and mite biology in relation to tree phenology, plans can be developed to protect fruit and maintain productive citrus trees. Populations of some highly …

In between seminar sessions, the trade show will become a tailgate party that you won’t want to miss. The day will kick off with breakfast and coffee in the tailgate hub. Attendees will have the opportunity to walk the …
Florida Citrus Commission (FCC) members on Jan. 17 heard an update on one recent Florida Department of Citrus (FDOC) scientific research project and learned about some future research plans. Rosa Walsh, FDOC director of scientific research, presented the information. PROGRAM FOR EXPEDITED PROPAGATIONWalsh reported that the 2022–23 Program for Expedited Propagation of HLB Tolerant and Resistant Trees was successful. She …
Brassinosteroids for HLB-infected trees and the latest on year-round weed management were discussed at a Jan. 17 OJ Break at the Citrus Research and Education Center in Lake Alfred, Florida. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) multi-county citrus Extension agent Chris Oswalt hosted the event. UF/IFAS assistant professors Fernando Alferez and Ramdas Kanissery made the presentations …
By Tripti Vashisth Huanglongbing (HLB) severity is associated with small fruit sizes and lower fruit numbers at harvest. Moreover, small fruit are more likely to drop and drop earlier during preharvest fruit drop. Unfortunately, management practices suggested to increase fruit size or reduce drop have had mixed results. So, before looking for ways to increase fruit size and number, it …
The Florida Citrus Show returns on April 3! Registration is now open for the 2024 show. Join us for a trade show full of the top agricultural companies, informational seminar sessions and an exciting tailgate party. This isn’t your average trade show. In between seminar sessions, growers can mingle with exhibitors and sample their tailgate dishes. Be sure to visit …
Robert Gilbert, who has served the past six months as University of Florida (UF) interim senior vice president for agriculture and natural resources, will serve in a full leadership role for at least another 18 months. Gilbert has served as University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research dean and interim senior vice president while Scott Angle …
By Randall P. Niedz, Guilherme Locatelli, Nick Larson, Lorenzo Rossi, Ellen Cochrane and Michelle Heck Scientists at the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) developed an idea to bypass lab assays and test molecules directly in the field for their ability to solve HLB. As part of a USDA National Institute of Food and Agriculture (NIFA) grant (number 2020-70029-33176), …
By Davie Kadyampakeni Huanglongbing (HLB) is a citrus disease that affects the growth of the fibrous roots of citrus trees. This means that HLB-affected trees may have reduced root volume, which impacts water uptake. A greenhouse study was conducted from October 2019 to July 2021 at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP My job is to help you make money. By changing the way the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) does business in pursuing citrus solutions, I hope to change your business for the better. We’ve just launched a UF/IFAS Crop Transformation Center (CTC). It has the potential to speed delivery …
By Jawwad A. Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) disease. The frequent availability of viable shoots in young trees is attractive to psyllid colonization, feeding and oviposition events. UV-metalized reflective mulches reflect ultraviolet light, which is disturbing for some insects …
By Clara Diekman and Michelle Danyluk The Food Traceability Rule (FTR) is a federal regulation that establishes recordkeeping requirements for persons who manufacture, process, pack or hold foods on the Food Traceability List (FTL). The goal of this rule is to help the U.S. Food and Drug Administration (FDA) identify and remove potentially contaminated food from the market more rapidly, …
In the December episode of the All In For Citrus podcast, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), gave a tip of the hat and congratulations to Ruth Borger who retired this fall.

Attention to nutrition, irrigation and soil health …
By Tripti Vashisth, Taylor Livingston and Jamie Burrow Canopy density is one of the most effective measurements to assess tree health of HLB-affected trees. Canopy density accurately distinguished between high and low fruit-producing trees in field trials, whereas CLas Ct value has been found to not be correlated with fruit yield. Many new tools such as nutrient management guidelines, plant …
