By Ramdas Kanissery Spot application of post-emergent herbicides provides an effective solution for controlling weeds that are missed by standard maintenance herbicide programs in citrus groves (Figure 1, left). This method is also helpful for targeting weeds in areas that herbicide boom sprayers can’t reach, like those growing near the trees (Figure 1, right). Here are some key tips to …
By Ozgur Batuman, Sanju Kunwar and Ana Redondo In a promising effort to protect citrus from huanglongbing (HLB), University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are exploring the potential of Australian lime as an interstock graft for Valencia scions with Swingle rootstock. The interstock technique uses various limes, known for their natural HLB-tolerant peptides, between the …
Recently, Steven Hall joined the Citrus Research and Field Trial (CRAFT) Foundation as its new executive director. The CRAFT Foundation is a private 501(c)(3) direct support organization of the Florida Department of Agriculture and Consumer Services Division of Plant Industry. It was incorporated in June 2019 to act as mechanism to direct and manage a broad-scale field-trial program to determine …
Initial assessments indicate that Alico, Inc. sustained minimal tree damage and some fruit drop from Hurricane Milton. The company stated that its approximately 48,000 acres of citrus groves in Charlotte, Collier, DeSoto, Hardee, Hendry, Highlands and Polk counties, Florida, sustained hurricane or tropical storm force winds for varying durations of time. Initial observations include measurable drop of fruit from trees …
By Ute Albrecht, Caroline Tardivo, Larissa Nunes, Gabriel Pugina, Gerardo Moreno and Jasmine de Freitas As growers are well into the second year of oxytetracycline (OTC) injections since approval for commercial use, more and more data are accumulating. The good news is that in all University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) trials, trees have been responding …
Hurricane Milton is currently expected to be a major hurricane when it makes landfall on Florida’s west coast late Wednesday night or early Thursday morning. It will likely impact a large portion of the state. In anticipation of the hurricane and its aftermath, Florida Citrus Mutual has canceled its crop estimate luncheon that was scheduled for Oct. 11 in Zolfo …
Individual protective covers (IPCs), used primarily to protect young citrus trees from HLB-spreading Asian citrus psyllids, have become ubiquitous in Florida citrus groves in recent years. New University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows the trees grown under the IPCs also grow well for a few years after growers remove the bags. Growers typically remove …
By Amir Rezazadeh The giant swallowtail butterfly (Papilio cresphontes) is a beautiful insect, admired for its large wingspan and vibrant yellow and black coloration. However, for citrus growers, this butterfly is often viewed with less enthusiasm. The larvae of the giant swallowtail, commonly referred to as “orange dogs,” can cause significant damage to citrus trees. Understanding the nature of this …
By Brenda Eubanks Burnette During this year’s Florida Citrus Industry Annual Conference in Bonita Springs, I interviewed a number of citrus growers as part of the Oral History Program. One of them was Brad Turner, who later sent me an article by E.F. DeBusk from the 1930 Proceedings of the Florida State Horticultural Society. DeBusk was a Florida Citrus Hall …
By Ramdas Kanissery Managing weeds during the summer is crucial for Florida citrus. However, due to the high temperatures typical of Florida’s summer months, several factors must be considered when using herbicides in citrus groves during hot weather. INCREASE EFFECTIVENESS High heat and drought stress can slow plant growth and affect how herbicides move or translocate in weeds. When temperatures …
By Ramdas Kanissery Finding the right time to apply post-emergent herbicides for controlling weeds in citrus groves is challenging in the summer months due to frequent rain. Rainy conditions delay grove maintenance, including herbicide spraying, while also impacting the effectiveness of the herbicides. Monitoring weather forecasts and identifying optimal conditions for herbicide applications can help achieve the best results. Below …
By Tom Spreen When citrus greening was first discovered in Florida, it did not have a profound impact on production. The big news at that time was the multiple hurricanes that had crossed Florida in 2004 and 2005. The hurricanes served to spread citrus canker so sufficiently that the state of Florida was forced to abandon its efforts to eradicate …
Phytophthora incidences are increasing in Florida citrus groves, plant pathologist Ozgur Batuman reported during a May 21 presentation. Phytophthora diseases include foot rot of trunk and limbs, root rot and brown rot. Batuman, a University of Florida Institute of Food and Agricultural Sciences associate professor, said these diseases led to yield reductions of 3% to 6% per year even prior …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center hosted a May OJ Break educational seminar. Ute Albrecht, UF/IFAS associate professor of plant physiology, spoke during the event and gave an update on oxytetracycline (OTC) therapies being applied in citrus groves over the past two seasons. She gave a summary of research she …
Alico, Inc. President and Chief Executive Officer John Kiernan recently discussed several Alico citrus grove transitions and transactions. Here are some of his comments that were included in an announcement of the company’s financial results for the period ending March 31. “To be clear, Alico will continue to conduct our regular citrus operations at nearly all of our groves for …
It was a dry April in most of Florida’s citrus-production areas. That means irrigation is vital to keep HLB-infected trees adequately watered. The drier months of the year from February through May are when flowering and fruit set are occurring. If trees are stressed due to water deficit during this time, they are more likely to suffer fruit drop and …
By Sarah Strauss The recent rising temperatures are a reminder that summer is approaching, and the beginning of the rainy season is a great time to start planting cover crops. If you are looking for a method to invest in your soil health, cover crops are one option. By definition, cover crops are planted to improve soil health and are …
Bill Lennon is working with researchers to learn more about survivor trees that are standing up to HLB. Bill Lennon is a fifth-generation citrus grower who can recall the industry’s glory days when Central Florida had hundreds of thousands of citrus acres before the 1980s freezes pushed production southward in the state. But he’s remained dedicated to the area, managing …
Total U.S. citrus production levels are projected to continue their long-term decline before stabilizing through 2033, the U.S. Department of Agriculture’s (USDA) Office of the Chief Economist recently reported. The trend is attributed to declining orange and grapefruit production alongside increasing production of lemons and tangerines. In the report, USDA Agricultural Projections to 2033, total U.S. citrus production is projected …
Growers have largely adopted new trunk-injection therapies to fight the effects of HLB in citrus groves. In addition, plant growth regulators have helped improve tree health and fruit retention. One University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist reminds growers to maintain their fertilizer programs as the new therapies are deployed. Davie Kadyampakeni, UF/IFAS associate professor of …
