By Ariel Singerman Four reports summarizing Florida citrus industry survey-collected data during the 2019–2020 season are available at https://crec.ifas.ufl.edu/economics/. The reports include the average cost of production for processed oranges, harvesting charges, custom rate (or caretaking) charges and packing charges. The estimates presented in those reports, as well as those available for previous seasons, document the changes in the industry …
By Manjul Dutt and Jude Grosser Finger lime, a distant relative of sweet orange and grapefruit, is a relatively new crop species for Florida. It is an Australian native species that has been gaining in popularity and importance in the last few years because of its unique fruit characteristics and disease tolerance, which sets it apart from conventional sweet orange …
By Yu Wang, Fred Gmitter and Jude Grosser A major concern for the citrus industry is a significant decline in production due to huanglongbing (HLB). In addition to the production shortfalls are losses due to fruit rejection by packinghouses and juice processing plants as a result of inadequate size and low sugar content. Bitterness and metallic off flavors in the …
By Rhuanito S. Ferrarezi, William S. Castle, Kim D. Bowman, Jude W. Grosser, Stephen H. Futch, Steve Rogers and Andres Gonzalez First published in 1989 as Rootstocks for Florida Citrus, the work of William Castle and his colleagues remains relevant 30 years later. The purpose of the fourth edition of the Florida Citrus Rootstock Selection Guide is to provide timely …
By Fernando Alferez and Tripti Vashisth As summer approaches and citrus trees bear developing fruit, growers can engage in several practices to improve fruit quality and yield. As temperatures rise and daylength increases, conditions are conducive for enhanced photosynthesis and accumulation of soluble sugars in the fruit. It is important to note that, in general, the temperature is negatively correlated …
By Sean Stokes, Thomas Borch and Pankaj Trivedi The benefits of soil organic matter (SOM) in agriculture have been well documented and include both improved water and nutrient retention. SOM is also essential for a properly functioning rhizosphere microbiome. However, the natural level of SOM in the sandy, acidic soil of Florida’s citrus grove regions is often around 1 percent, …
In his quest to find the right drone and other artificial intelligence to help ensure citrus growers get an accurate count of their crop, Yiannis Ampatzidis and his research team have developed a system known as Agroview. The technology saves farmers time and money and helps them accurately count their trees, which is important for insurance purposes. The latest results …
Sweet oranges. Ruby red grapefruit. Sugar Belle mandarins. When one thinks of Florida citrus, these fruits immediately come to mind. But finger limes? A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher believes that finger limes may be the next food trend that will continue to fortify Florida’s role as a citrus producer for the world. Manjul …
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 …
Florida citrus growers hit hard by citrus greening can benefit from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) expertise in an updated book — the third edition of the Nutrition of Florida Citrus Trees. Greening, known scientifically as huanglongbing (HLB), has caused significant damage to Florida’s citrus industry. UF/IFAS scientists and Extension faculty have updated the guide …
By Ramdas Kanissery, Justin George and Lukasz Stelinski Weed management is a crucial component in Florida’s citrus production. Recent University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows that weed management may have additional pest management benefits for citrus growers. Maintaining a weed-free grove and perimeter areas may help improve management of the Asian citrus psyllid (ACP), …
By Davie Kadyampakeni, Arnold Schumann, Mongi Zekri and Chris Oswalt Irrigation management is important for achieving optimal citrus tree growth and promoting high water- and nutrient-use efficiencies in young trees. In the era of HLB, poor water-management practices, such as infrequent irrigation, lead to water stress in trees resulting in limited growth and impaired root development. On the other hand, …
By Rhuanito Soranz Ferrarezi, Dinesh Phuyal, Davie Kadyampakeni and Kelly Morgan The Indian River District is the world’s premier grapefruit production region due to a warm, ocean-facing humid climate and Flatwoods soils. The geographical location leads to the production of fruit with thin rinds and exceptional juice and color that has been a high-value export delicacy in Europe and Asia. …
By Tripti Vashisth Constant supply and soil application of macronutrients and micronutrients can improve the health and productivity of HLB-affected citrus. A 20 to 50 percent higher than University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recommended rate of micronutrients is beneficial for HLB-affected trees. However, the nutrition program should be customized for each grove, as no one …
The March issue of Citrus Industry magazine focuses on fertilization and other production practices to keep citrus trees healthy. Tripti Vashisth’s article summarizes a three-year University of Florida (UF) study that looked at 10 different controlled-release fertilizer treatments in two different locations. The research results revealed that when it comes to citrus nutrition, one size does not fit all. Surprisingly, …
A sheet of “Nutrient Management Concept Questions” was passed out at the January Citrus Research and Development Foundation (CRDF) board meeting in Fort Pierce. It included questions that growers and researchers have agreed need to be answered in future nutrition-related research funded by CRDF. Rick Dantzler, CRDF chief operating officer, explains how the questions were developed. “We had a Nutrition …
Scouting: The tip of the IPM spear By Matt Smith Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. Why would you scout? Despite what we were all promised by Tomorrowland and …
By Clint Thompson Georgia growers interested in adding citrus to their farming operation are invited to the fourth annual Georgia Citrus Association Conference on Monday, Feb. 24, at the University of Georgia (UGA) Tifton Campus Conference Center. Scientists from UGA and the University of Florida, as well as producers who are already growing citrus trees, will be in attendance to …
By Jude Grosser, Manjul Dutt and Fred Gmitter The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus improvement team at the Citrus Research and Education Center (CREC) has developed a broad citrus germplasm base. This provides opportunities to generate diverse, interesting and possibly lucrative selections with niche market and dooryard potential. Several such selections are showing reasonable …
