When news broke in July that University of California Riverside (UCR) scientists had found a peptide that might control HLB, Rick Dantzler quickly contacted lead UCR scientist Hailing Jin. Dantzler is chief operating officer of the Citrus Research and Development Foundation (CRDF), which was organized in Florida primarily to find ways to solve or cope with HLB. Jin had found …
Feral citrus growing in natural hammocks reveals insights about production and HLB. By Christopher Vincent and Anirban Guha Would you rather go outside in August and stand for a few hours in the sun or in the shade? It turns out citrus prefers the shade, too. In the past two years, we have been researching the health of citrus growing …
University of Florida Institute of Food and Agricultural Sciences citrus horticulturist Fernando Alferez and multi-county citrus Extension agent Mongi Zekri co-authored a new document on the U.S. Department of Agriculture’s Hurricane Preparation and Recovery Commodity Guides website. The Citrus Producers Guide includes long- and short-term recommendations for building resilience to hurricanes in citrus groves, nurseries and citrus under protective screens …
The July issue of Citrus Industry magazine focuses on what’s new in rootstock research. When choosing a rootstock in the Sunshine State, the best place for a grower to start is with the Florida Citrus Rootstock Selection Guide. This newly updated University of Florida (UF) resource now includes an interactive web version to help simplify the process of picking a …
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 …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus scientists Tripti Vashisth and Fernando Alferez are trying to reduce the amount of fruit drop from Hamlin and Valencia trees prior to harvest. If fruit drops, growers can’t harvest it, and that leads to losses for farmers and less fruit at the market for consumers. Normally, about 10 to …
Brazil released its first orange crop forecast for the 2020-21 season on May 11. According to a report published by Fundecitrus and its cooperators, 287.76 million boxes are expected for the season for the São Paulo and West-Southwest Minas Gerais citrus belt. The projected figure is 25.6 percent smaller than the previous crop of 386.79 million boxes, and 12.5 percent …
Brazil reported it will produce 386.79 million boxes of oranges in the 2019–20 season. This is the final forecast for the season and includes production from the São Paulo, Triângulo Mineiro and West-Southwest Minas Gerais Citrus Belt. Fundecitrus, in cooperation with Markestrat, FEA-RP/USP and FCAV/Unesp2, published the forecast on April 9. It represents a decrease of 0.54 percent compared to …
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 Kim D. Bowman and Ute Albrecht The US-1283 rootstock was released by the U.S. Department of Agriculture (USDA) in 2014, based on field performance with Hamlin 1-4-1 sweet orange in trials at two different locations in Florida severely affected by huanglongbing disease. One of these trials was in St. Lucie County and of 14 years duration, while the second …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) geneticist and plant breeder Jude Grosser discusses the need for new juice oranges and some new cultivar choices. Grosser says one reason for new varieties is the decline in orange juice sales. “In my opinion, the best way to combat that is to have a higher quality orange juice that’s …
By Megan Dewdney and Evan Johnson In 2019, the trend of fewer problems with foliar fungal diseases for Florida citrus continued, which was good news for the industry. Despite the El Niño conditions during the spring, little postbloom fruit drop (PFD) was observed because the temperatures were low (< 75 F) when it rained during bloom. The southern parts of …
New sweet orange cultivars for processing can be harvested throughout the Florida citrus season. By Jude Grosser, Fred Gmitter and Bill Castle Florida orange juice has always been the gold standard among the growing portfolio of fruit juices and blends available to consumers. However, the now endemic citrus greening disease or huanglongbing (HLB) threatens this status by causing reduced fruit …
By Nabil Killiny A dynamic research collaboration between several labs at Washington State University (Gang, Beyenal and Omsland labs), University of Arizona (Brown lab) and University of Florida (Killiny lab) recently reported an important step in the long-sought culture of the bacterium [Candidatus Liberibacter asiaticus (CLas)] associated with huanglongbing (HLB). The work, published in the journal Biofilm, describes a new …
Growers recently sampled and graded new fruit varieties, as well as some juice blends, at University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) fruit display events. UF/IFAS plant breeder Jude Grosser commented on the fruit varieties and juice following a sampling event at the Citrus Research and Education Center. “It’s kind of neat because when we first started …
Polk County grower Ed Dickinson has good things to say about some orange-mandarin juice and fresh mandarins he sampled at the Citrus Research and Education Center (CREC) in November. Dickinson was one of dozens who tried new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) samples. He and others who scored the juice and fruit will help researchers …
By Stephen H. Futch and Rhuanito S. Ferrarezi Many changes have taken place in the Brazilian citrus industry over the past 20 years as growers battle pests, diseases and market challenges. Throughout this process, the industry has encountered difficulties but has continued to maintain production through innovative practices that are founded in science, economics and sustainability. This article provides an …
By Bill Castle If timing is everything, then let me suggest that the timing is right to consider the following proposals about making scion and rootstock choices in the Florida citrus industry: What to plant? That is a huge question that could be initially addressed by a one-day program carefully planned as to objectives, format and participants. I was reminded …
A citrus soil health field day recently attracted about 40 people to the Howey-in-the-Hills area to see growers’ success using cover crops and compost on Florida groves once stunted by HLB. Event organizer Juanita Popenoe, commercial fruit production Extension agent for Lake, Marion and Orange counties, comments on the groves’ success. Popenoe is with the University of Florida Institute of …
