By Megan Dewdney The Florida rains have finally come this summer, just in time for early-season fruit to start the maturation process. This means there is some risk of brown rot in early sweet oranges and grapefruit. Much of Florida has been getting summer storms, wetting the soil. While this is excellent in general, the downside is that it allows …
Three University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers recently issued the document Suggested Use Pattern of Injectable Antimicrobials for Huanglongbing (HLB) Management. The authors are Ute Albrecht, associate professor of horticulture; Ozgur Batuman, associate professor of plant pathology; and Megan Dewdney, associate professor of plant pathology. 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 …
By Tripti Vashisth, Maricielo Postillos and Taylor Livingston In recent years, many citrus growers in Florida have begun using gibberellic acid (GA) to enhance tree growth and productivity. Initially, the recommendation was to apply GA monthly from September to January for Valencia oranges to maintain canopy health, reduce fruit drop and improve yields. However, some growers are hesitant about applying …
The May All In For Citrus podcast features highlights from a recent OJ Break hosted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) in Lake Alfred. Podcast host Frank Giles caught up with Michael Rogers, CREC director, during the event. Rogers summarized some of the information presented at the OJ …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center hosted an OJ Break seminar on May 14. The speakers provided updates on developing a gene-edited citrus tree with resistance to HLB and how growers can use existing tools to mitigate the disease. Nian Wang, UF/IFAS professor, provided an update on the status of …
By Jawwad A. Qureshi Several insect pests and mites colonize citrus crops in traditional open orchards. Most pests are localized and are suppressed by predators, parasitoids and entomopathogens to levels that are not economically damaging to the crops. The Asian citrus psyllid (ACP) is the primary vector of huanglongbing (HLB) disease. Despite biological and chemical control of ACP, growing a …
Growers in the cold-hardy citrus region are applying too much nitrogen to their groves. Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), discovered that unfortunate reality while conducting a research project in North Florida. Most citrus growers were following recommendations in the UF/IFAS Florida Citrus Production Guide, which are mostly …
By Maegan Beatty During a recent citrus insect management workshop at the Citrus Research and Education Center, Larry Duncan, University of Florida Institute of Food and Agricultural Sciences professor, addressed diaprepes root weevil management. This Caribbean pest was introduced to Florida in the 1960s. The adult pests feed and lay eggs in citrus tree canopies. The larvae feed on roots …
By Davie Kadyampakeni, Kondwani Kamsikiri and Alisheikh Atta Water scarcity is one of the major constraints in Florida citrus production systems, primarily due to erratic rainfall patterns and the low water- and nutrient-holding capacity of the predominantly sandy soils. The state’s soils contain more than 95% sand and have low organic matter (<1%) and very low water-holding capacity. These challenges …
Citrus trees used to be a common site around Florida homes, but diseases like canker and greening have diminished residents’ ability to enjoy these iconic trees. Despite the challenges, people from Florida and across the country contact citrus nurseries this time of year, seeking to purchase trees for their yards and/or homes. It’s a passion, say nursery owners and University …
By Tripti Vashisth and Prudhvi Vulchi To mitigate the effects of huanglongbing (HLB) on tree health and productivity, growers are encouraged to adopt proven horticultural practices. Based on recent field trials at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), one effective approach combines frequent irrigation (FI), plant growth regulators (PGRs) …
By Brenda Eubanks Burnette I was honored this year to be part of the Vero Heritage Center and Indian River Citrus Museum’s “Deeply Rooted” event, which was the kick-off for Indian River County’s Centennial Celebration. It made me think of this year’s Florida Citrus Hall of Fame inductees. They all have something in common with deep roots — Polk County! …
By Maegan Beatty During the recent citrus insect management workshop at the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center, Larry Duncan, a nematology professor, discussed the sting nematode. First recognized in the 1980s as a pest of young citrus trees, the sting nematode has adapted to coarse, sandy soils. The pest feeds at …
By Maegan Beatty Last month, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a citrus insect workshop that covered almost 10 different pests that pose a threat for Florida citrus. Lance Osborne, professor and researcher at the Mid-Florida Research and Education Center, presented research on chilli thrips. Chilli thrips (Scirtothrips dorsalis) can live in over 150 …
By Megan Dewdney Despite being in a transition from a La Niña to a neutral El Niño Southern Oscillation phase, Florida has not had warmer than average temperatures in the last two weeks from March 3. Looking at historical trends, temperatures for the last two weeks of February were in the normal range for this time of year. When looking …
By Megan Dewdney Spring is the time to start thinking about foliar disease management in Florida. Depending on the type of citrus being produced and the market destination, different diseases will be important. POSTBLOOM FRUIT DROP The disease that affects all citrus, particularly oranges, is postbloom fruit drop (PFD). This disease is highly dependent on the weather during bloom. Currently, …
By Ramdas Kanissery Tackling herbicide tolerance in weeds is a critical aspect of effective weed control in citrus groves. It helps prevent both current and future weed management challenges. Herbicide tolerance occurs when certain weed species naturally survive and reproduce after herbicide treatment. Unlike herbicide resistance, where genetic changes allow weeds to survive and spread, herbicide tolerance doesn’t involve any …
After being postponed this fall due to Hurricane Milton, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted its annual Citrus Nutrition Day on Jan. 22 at the Citrus Research and Education Center (CREC) in Lake Alfred. The event was well attended and featured several presentations aimed at optimizing citrus nutrition programs in the HLB era. UF/IFAS …
Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are testing a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse but is very promising as a potential solution to HLB. The approach involves inserting a …
