While many citrus growers use similar strategies to cope with HLB, no two approaches are exactly the same. One grower who uses a very different method to manage citrus greening is Chip Henry. In the May cover story of Citrus Industry magazine, he tells how growing organically has helped him successfully fight the disease. Sometimes, production practices aimed at protecting …
Weed scientist Ramdas Kanissery’s research has not shown evidence that herbicides, including glyphosate, increase citrus fruit drop or decrease yields. But in studies using different glyphosate rates, he did find that there is a relatively strong negative correlation with the fruit detachment force and the glyphosate amount applied. “That means there may be something happening with the higher glyphosate rate” …
By Bill Castle Today, at least three things seem to be true about Florida citrus rootstock field trials: There is an unprecedented number of them underway or soon to be planted. The sponsors are many, including the University of Florida, U.S. Department of Agriculture, Citrus Research and Development Foundation, Citrus Research and Field Trial Foundation and the Multi-Agency Coordination Group. …
Florida citrus growers need help in the fight against HLB. And they need that help quickly. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, addresses those concerns during the April All In For Citrus podcast. He says UF/IFAS scientists understand the urgency of the HLB fight and that …
By Davie Kadyampakeni and Evan Johnson In the era of citrus greening disease (huanglongbing, HLB), maintaining optimal nutrition and disease/pest management strategies is critical for avoiding adverse effects on tree performance. Use of the right fertilization rate, timing and placement are important for optimal citrus production. In a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research study, …
By Thomas H. Spreen Citrus under protective screen (CUPS) is a relatively new technology being adopted to help spur expansion of fresh citrus production in Florida. Large screen houses (approximately 10 acres) are constructed. In the current arrangement, several screen houses are located together to facilitate caretaking and harvest. Trees are planted at high densities (more than 300 trees per …
Florida citrus growers can learn more about the use of plant growth regulators (PGRs) in the fight against fruit drop at an upcoming online seminar. The webinar will be at 10 a.m., April 27 and will be presented by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Speakers at the webinar, titled “Gibberellic Acid Research Update and …
By Ariel Singerman and Stephen H. Futch Chemical input prices have increased significantly over the last year. In particular, the price of fertilizer has roughly doubled during the last 12 months, as denoted by Figure 1. Figure 1. Producer Price Index of Nitrogenous Fertilizer Manufacturing Source: Federal Reserve Bank of St. Louis Supply and demand factors help explain such an …
By Tripti Vashisth and Faisal Shahzad Mandarin production has been increasing in Florida since some mandarin varieties can potentially withstand HLB better than sweet orange varieties. Mandarin varieties such as Tango are popular among growers. However, Florida weather poses challenges for the external fruit quality; the peel color is often not satisfactory. Warm night temperatures in fall inhibit chlorophyll breakdown, …
By Hailing Jin Research on the effectiveness of a novel stable antimicrobial peptide (SAMP) identified from the Australian finger lime (Microcitrus australasica) to fight huanglongbing (HLB) continues in a multistate initiative involving 1,500 citrus trees. Although the pandemic has impacted the progress of the research, work has steadily continued and expanded. Researchers at the University of California, Riverside and University …
Matt Joyner, Florida Citrus Mutual’s (FCM) new chief executive officer and executive vice president, recently reported that FCM helped achieve substantial citrus industry support in the recent Florida legislative session. Following are citrus-related items that Joyner highlighted in the recently passed state budget: $8 million for the Citrus Research and Development Foundation (CRDF) to continue basic research into HLB ($3 …
By Kelly T. Morgan and Davie Kadyampakeni Most information provided in the 2020 3rd edition of Nutrition of Florida Citrus Trees is still sound for healthy citrus trees under Florida production conditions. Past information on nutrients, application methods, leaf and soil sampling, and irrigation scheduling are also effective for management of huanglongbing (HLB)-affected trees. However, research conducted since HLB was …
Growers gathered in Avon Park at South Florida State College for the Florida Citrus Growers’ Institute on April 5. The event, organized by regional citrus Extension agents with the University of Florida Institute of Food and Agricultural Sciences, aims to provide timely research that can be applied in groves today. It also was an opportunity for growers to get updates …
John Chater joined the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) in January as an assistant professor of horticultural sciences. His mission is to act as a conduit between citrus plant breeders and growers to find fits for new rootstock and scion selections. Chater’s love of plants was inspired by his grandfather who was a plant breeder …
Total U.S. orange juice (OJ) production in the current 2021–22 season is forecast at 286 million single-strength equivalent (SSE) gallons, the U.S. Department of Agriculture’s Economic Research Service reported recently. If realized, this volume will be the lowest in more than 50 years. To compensate for lower production, U.S. OJ imports are expected to increase over last year, reaching more …
After being presented virtually for the past two years as a result of COVID-19, the 2022 Florida Citrus Growers’ Institute will once again be an in-person event on April 5. The event will be held from 8:30 a.m. to 3 p.m. at South Florida State College’s Alan Jay Wildstein Center for the Performing Arts in Avon Park. The institute is …
Increased attention on nutrition has become part of the overall strategy for managing HLB. The April issue of Citrus Industry magazine includes several articles on nutrient management designed to help growers keep trees productive in the HLB era. Mandarin growers will want to take note of new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research on how …
By Christopher Vincent, Megan Dewdney and Liliana Cano Bingo mandarin hybrid is a variety with many promising characteristics, but it brings specific challenges to profitable production. One challenge identified early in the push to plant Bingo was stem dieback that led to tree loss. After looking into this problem for the past four years, University of Florida Institute of Food …
The Citrus Research and Development Foundation (CRDF) had a busy board of directors meeting in March. Rick Dantzler, CRDF chief operating officer, says the board utilized a new approach in seeking and approving research projects during the meeting. “The board advanced a number of research topics through the vehicle of ‘directed research’ where we negotiate with specific scientists who we …
The Australian finger lime has created a buzz among chefs and mixologists for its caviar-like texture and flavorful pulp. The fruit also has captured interest among growers for its seemingly high tolerance to HLB. On March 23, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a half-day online symposium on finger limes to provide growers with …
