Not surprisingly, the focus of the Citrus Research and Development Foundation (CRDF) centers on providing growers with help to overcome huanglongbing (HLB) disease. CRDF President Morgan McKenna Porter believes that help will best come with the development of the “tree of the future.” She says that tree does not have to be completely resistant to citrus greening. As long as …
A recent issue of the Annual Review of Phytopathology contains the article, “Management of huanglongbing of citrus: Lessons from São Paulo and Florida.” It discusses the lessons in HLB management, comparing what was done in orchards in Brazil’s state of São Paulo and in Florida. It also highlights the measures that worked and failed from the perspective of controlling the …
Last week, growers convened in Avon Park for the annual Florida Citrus Growers’ Institute. The daylong seminar program provides updates on the latest research in the fight against HLB and other production issues facing growers. Rick Dantzler, chief operating officer of the Citrus Research and Development Foundation (CRDF), presented an update on the organization’s research priorities. He noted that CRDF …
Citrus greening or huanglongbing (HLB) continues to impact all citrus production areas of Florida. The 2024 Florida Citrus Growers’ Institute is an opportunity for Florida citrus growers to come together to learn about effective management of HLB and other challenging pests and diseases affecting the industry. Topics this year include horticultural management of HLB, citrus nutrient management and management of …
The February board meeting of the Citrus Research and Development Foundation (CRDF) covered a lot of ground according to Rick Dantzler, the foundation’s chief operating officer. “We had a big day on the day of the board meeting. There were three meetings: 1) our monthly board meeting; 2) a research summit with citrus organization leaders, the CRDF board and CRDF …
The Citrus Research and Development Foundation (CRDF) kicked off the new year with a full agenda for its monthly board meeting. New members were welcomed to the board. Growers Matt Machata, Sarah Spinosa and Trevor Murphy joined the group. On the research front, the board funded continued work by Ping Duan, a plant pathologist with the U.S. Department of Agriculture. …
By Jawwad A. Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) disease. The frequent availability of viable shoots in young trees is attractive to psyllid colonization, feeding and oviposition events. UV-metalized reflective mulches reflect ultraviolet light, which is disturbing for some insects …
By Davie Kadyampakeni, Lorenzo Rossi and Alan Wright Huanglongbing (HLB) disease lowers tree performance by reducing water and nutrient uptake as a result of root loss. HLB-affected trees have a fibrous root loss of about 30% to 80%, which increases as disease symptoms develop in the canopy. Investigating optimal nutrient concentrations in citrus roots thus improves the understanding of HLB …
It’s no secret that Florida’s citrus industry has seen significant shrinkage since the advent of citrus greening in the state. In the December issue of Citrus Industry magazine, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) economist Ariel Singerman takes an in-depth look at the acreage attrition. He examines the figures by county over the past 20 years. …
The Florida Department of Agriculture and Consumer Services (FDACS) announced that the state’s citrus growers reauthorized the Florida citrus research order in a statutorily required referendum conducted by the department. The results of the ballots returned yielded 76% “yes” votes representing 69% of total citrus acres. The Florida Citrus Research Order has a six-year cycle and is subject to renewal …
By Kim D. Bowman The breeding of new citrus rootstocks is not an endeavor for the impatient. Two of the most popular rootstocks in Florida, US-942 and US-812, each were included in field evaluation for more than 20 years before the U.S. Department of Agriculture (USDA) released them for commercial use. In these cases, the time invested in thorough testing …
As the voting period for the Florida Citrus Research Order winds down, it is important that growers have a clear understanding what the vote is for and the role the Citrus Research and Development Foundation (CRDF) plays in the process. Rick Dantzler, chief operating officer of CRDF, says this clarification is important to be sure growers have the correct information, …
The Citrus Research and Development Foundation (CRDF) Research Management Committee and board of directors recently approved projects for funding. The first CRDF research project has approval for funding of a final year of research by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to study the lebbeck mealybug and its management. “The Research Management Committee debated this …
The Citrus Research and Development Foundation (CRDF) is seeking Florida citrus growers on the Ridge and in the flatwoods of Southwest Florida to potentially be grower-cooperators in large rootstock trials. The goal of the new trials is to identify plant material with the traits needed by growers to realize the highest possible pound solids per acre and increase tree viability …
The Citrus Research and Development Foundation (CRDF) held its April board of directors meeting to hear reports on projects involving 2,4-D, gibberellic acid, brassinosteroids and zinc. According to Rick Dantzler, chief operating officer of CRDF, the foundation is conducting a full-court press to study how these materials can combat fruit drop and improve quality. CRDF staff also presented a proposal …
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. …
Due to the initiative of the Indian River Citrus League (IRCL), the Citrus Research and Development Foundation (CRDF) has approved research funding for the greasy green defect on citrus fruit. At a 2021 IRCL board meeting, the issue of greasy green spot was brought up by Tim Sallin of IMG Citrus. Other growers at that meeting also shared their experience …
The urgency is high to find any solution to help citrus growers more effectively mitigate HLB. During the Florida Citrus Growers’ Institute this month, Citrus Research and Education Center director Michael Rogers gave a presentation that outlined the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research projects aimed at finding short-term HLB solutions. “We understand where the …
The Florida Citrus Mutual (FCM) board of directors voted earlier this month to support the continuation of the Florida Research Order. It encouraged Florida citrus growers to vote for continuation in a May referendum. The board acted after hearing from Citrus Research and Development Foundation (CRDF) Chief Operating Officer Rick Dantzler and discussing the importance of a continued funding mechanism …
