Many of the citrus presentations featured on the first day of Citrus Expo, Aug. 18, will focus on “what growers can do now” to keep groves productive, Michael Rogers reports. Rogers, director of the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center, offers what he calls “a 30,000-foot view” of the citrus seminar …
New research affirms a unique stable antimicrobial peptide (SAMP) found in an Australian plant can destroy HLB and help prevent infection. Hailing Jin, University of California Riverisde geneticist who led the research, shared the exciting discovery during the 2021 Florida Citrus Show. The naturally occurring peptide is found in HLB-tolerant citrus relatives, such as the Australian finger lime. The peptide …
Florida citrus growers may have a new tool to help them slow the presence of HLB in already diseased trees, courtesy of researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The researchers found that injecting a benign Xylella fastidiosa EB92-1 bacteria biocontrol into infected citrus trees over a period of six years reduced the incidence …
The Citrus Research and Development Foundation (CRDF) received 59 proposals for funding of projects in response to the organization’s recent request for proposals (RFP). “This is the best RFP we’ve ever done since I’ve been here,” said CRDF Chief Operating Officer Rick Dantzler. The deadline for submitting proposals was April 26, a day before the CRDF’s board of directors …
New citrus technology and tried-and-true techniques are among the article topics in the May issue of Citrus Industry magazine. Yiannis Ampatzidis, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, discusses several ways artificial intelligence is being used to improve citrus production and reduce negative environmental impacts. Among the topics he covers in his article are automated …
Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are using RNA interference (RNAi) to alter field populations of the Asian citrus psyllid (ACP). Nabil Killiny, UF/IFAS associate professor, shared the latest findings from his team’s RNAi research in a recent All In For Citrus podcast episode. He says the team is using RNAi to attack …
Citrus Research and Development Foundation (CRDF) directors on March 23 voted to request research proposals from scientists in nine topic areas for the coming year. The nine areas, mostly focusing on HLB, are: Understanding the mechanisms for increasing fruit retention in HLB trees by manipulating hormonal balance in the fruit and the tree or by altering the relationship between vegetative …
Ask any Florida citrus grower what the top priority is, and you’ll likely get the same answer: Keeping HLB-affected trees productive and profitable. The April issue of Citrus Industry magazine provides research on production practices aimed to meet this goal. Adjusting the amount of sunlight plants receive has proven to increase citrus tree health and yield. University of Florida Institute …
By Sylvia Willis, Amy Vu and Jamie Ellis When people think of Florida, the first thing that comes to mind is Fresh From Florida oranges. Florida accounts for 44 percent of total U.S. citrus production. Citrus, like many other fruits, vegetables and specialty crops, requires certain inputs to grow and produce fruit. But how are pollinators and the production of …
Encouraging news stories have appeared in recent months on the possible benefits of using peptides in the fight against HLB. Peptides, small groups of linked amino acids, have many functions, including acting on pathogens. As researchers continue to investigate the role of peptides in the fight against HLB, they are also looking for the most effective delivery method of these …
In 2016, federal authorities began allowing Florida citrus growers to spray oxytetracycline solutions on their trees to combat citrus greening disease. Since then, researchers have been investigating oxytetracycline delivery methods. In a Citrus Expo presentation, Christopher Vincent, assistant professor of horticultural sciences at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, shared …
By Davie Kadyampakeni Proper irrigation scheduling applies an appropriate volume of water to a citrus grove at the appropriate time based on tree need, soil properties and weather conditions. Applying water in the right amount, right quantity and at the right time is very important for getting the best out of citrus trees. Several tools are available for determining when …
By Larry Duncan, Johan Desaeger and Sheng-Yen Wu The citrus row middle habitat changed profoundly beginning in the 1970s as mowing replaced disking for weed management. This change ended the costly cycle of cutting and regrowing citrus roots near the soil surface and reduced soil erosion, among other benefits. Mowing also allowed a seasonal succession of native plants to flourish, …
Citrus growers can get continuing education units (CEUs) from the 2020 Florida Citrus Growers’ Institute, even though the in-person version of the annual event was cancelled due to COVID-19. Multi-county citrus Extension agent Chris Oswalt discusses how growers and others can get their restricted-use pesticide license or Certified Crop Advisor CEUs. “We have started to receive those presentations from those …
According to a news article released by the University of California Riverside (UCR), scientists there have found a substance which may be capable of controlling citrus greening disease. The disease, also known as huanglongbing (HLB), has devastated citrus in Florida and in other regions worldwide. It also threatens California crops. The article says the new treatment effectively kills the bacterium …
When the annual 2020 Florida Citrus Growers’ Institute was canceled due to the stay-at-home guidelines recommended by the state, growers were shut out of learning the latest research updates from University of Florida citrus scientists. In addition, they were denied access to earning valuable continuing education units (CEUs) needed to renew pesticide licenses. University of Florida/Institute of Food and Agricultural …
A new University of Florida Institute of Food and Agricultural Sciences Extension document, Antibiotics in Crop Production, was published in May by Leigh Archer, Ute Albrecht and Pamela Roberts. The authors found that the use of antibiotics has resulted in the successful control of bacterial diseases in some crops but not in others. The publication includes research information on antibiotics …
Citrus, olives and bananas are under threat in many areas due to diseases that affect plants’ circulatory systems and that cannot be treated by applying pesticides. Huanglongbing (HLB) is the disease inflicting heavy damage on citrus in Florida and many other parts of the world. These diseases are difficult to detect early and to treat, given the lack of precision …
By Davie Kadyampakeni and Arnold Schumann Irrigation system maintenance is critical for proper and efficient delivery of water in citrus and other irrigated crops. A well maintained and functional irrigation system will deliver the required amounts of water to the root zone when needed and help growers optimize crop production. If an irrigation system is not working optimally, crops can …
By Aaron Himrod Good nursery growers are constantly monitoring their nutrition levels to produce well-nourished plants. While a grove owner cannot employ the same intensity of nutritional control as in an enclosed structure with consistent plant media, the principles apply in the field just as much in the nursery. A steady supply of comprehensive nutrition in the appropriate balance is needed …
