By Jamie D. Burrow and Tripti Vashisth The UF/IFAS Citrus Team conducts ongoing research to improve citrus production management strategies. The Citrus & Specialty Crop Expo is one of the main annual events where the team comes together to showcase the latest research and tools available to citrus growers. For more than 20 years, the citrus team has had a …
By Jamie D. Burrow, Tripti Vashisth and Michael E. Rogers In the early days of huanglongbing (HLB), the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Team realized it needed to bring its HLB content together on a single website to make it more accessible. The website has become outdated, and much more is available today for …
Compost-amended plots (left) had more weeds than those with no compost. A new study published in Scientific Reports examines whether repeated compost applications could improve the health and productivity of young citrus trees growing under endemic huanglongbing (HLB) conditions in Florida. Gabriel Pugina, Caroline Tardivo, Brittney Monus, Emma Dawson, Sarah Strauss and Ute Albrecht of the University of Florida Institute …
By Ramdas Kanissery When the summer heat rolls in and the rain gets spotty, growers tend to shift their focus to irrigation, nutrition and HLB management. Weed control often gets pushed to the back burner. But here’s the thing: Heat and dry spells do not stop weeds. They change them, and those changes can make your weed management program a …
By Ramdas Kanissery Spring is here and so are the weeds in citrus groves. Warmer temperatures and increasing soil moisture create ideal conditions for weeds. Growers often notice a rapid spring flush of weeds emerging in the tree rows and in the row middles during this time (Figure 1). If not managed early, these weeds can compete with citrus trees …
By Lauren Diepenbrock Citrus under protective screen (CUPS) has provided growers with a profitable method for producing fresh fruit in Florida. Growers who have implemented this system have noted quality fruit production and reduced inputs. However, when changes are imposed to the production environment, they are also imposed to the invertebrate pest complex, which can be either beneficial or detrimental …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a statewide citrus grower workshop in mid-January at the Southwest Florida Research and Education Center in Immokalee. The event offered a full day of education covering a wide range of topics, including management of pests, diseases, weeds and nutrients. Ute Albrecht, UF/IFAS associate professor of plant physiology, provided …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have long extolled the virtues of individual protective covers (IPCs). Multi-county citrus Extension agent Edwin Gutierrez-Rodriguez does the same but also warns of potential risks. Following is information from a recent UF/IFAS blog article he authored. In the ongoing battle against huanglongbing (HLB), also known as citrus greening disease, …
By Muhammad A. Shahid, KeAndre Leaks and Davie M. Kadyampakeni Right after a freeze, you may notice new growth turning black and leaves hardening, yellowing or looking water-soaked. About a week after a severe freeze, leaves may start to curl and turn brown. Leaves and fruits may begin to drop. Do not attempt any recovery treatments immediately after a freeze. …
The Florida Fruit & Vegetable Association (FFVA) recently filed comments with federal agencies supporting continued access to the triazine herbicides simazine and atrazine for citrus and other specialty crops. The comments were submitted to the U.S. Fish and Wildlife Service (FWS) and Environmental Protection Agency regarding FWS’ draft Biological Opinion (BiOp) for Atrazine and Simazine Herbicides. FFVA submitted the comments …
By Ramdas Kanissery Young citrus trees are highly sensitive to herbicides. Even small amounts of drift onto green bark or foliage can significantly impact tree growth (Figure 1). Taking a few practical precautions during herbicide applications can help protect young trees and keep them growing strong during their early establishment years. AVOID HERBICIDE CONTACT WITH GREEN BARK The greatest risk …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers recently explained the benefits of raised bed planting and mulching to improve citrus tree establishment, productivity and resilience against environmental stress. Assistant Professor Muhmmad Shahid and Postdoc Scholar Shahid Iqbal, both of the North Florida Research and Education Center, and Associate Professor Davie Kadyampakeni of the Citrus Research and …

A bed system used in citrus groves is still under research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) in Quincy. But one researcher is already convinced that the system, which includes fabric mulch, is beneficial for growers. “This system is better for them. It’s already being used in …
Citrus under protective screen (CUPS) continues to spread across the Florida landscape. The practice is allowing growers to produce high-yielding and high-quality fruit. Roughly 1,500 acres are now planted under screen in Florida. MEET CUPSchat Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor of soil, water and ecosystems sciences, pioneered CUPS research in Florida. His …
By Sarah Strauss One of the keys to good cover crop germination, and thus the potential benefits to soil health, is timing planting with summer rains. As cover crops are planted to improve soil health and are not harvested for profit, you want them to require as little effort on your part as possible. Relying on rain for irrigation can …
By Ramdas Kanissery As the summer season of weed control kicks off in citrus groves, now is the perfect time to make sure your spray rigs are set up for success. Effective weed control depends on: In many cases, poor herbicide performance is caused by two main issues: spraying at the wrong time and using incorrect application techniques. We’ve already …
