With an investment of $200 million (in Brazilian reals), three citrus research organizations in Brazil have partnered to create a research center in São Paulo to seek solutions to citrus greening. The São Paulo Research Foundation (FAPESP), Fundecitrus and Luiz de Queiroz College of Agriculture at University of São Paulo (ESALQ-USP) agreed on Jan. 12 to establish the Applied Research Center …
Fruit harvested at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Millennium Block from 2022 to 2026 will help determine the effectiveness of potential solutions to HLB. This season’s fruit will be harvested through early February, and research results are expected later this year. The Millennium Block was planted in 2019 at the UF/IFAS Indian River Research …
Sponsored Content Question: Now that we have ReMedium TI® as a therapy to treat HLB, what else can a grower do to speed recovery? Answer: Feed the trees. I know that answer is an oversimplification, but it is the correct answer. Your groves have been struggling for years because of the root damage from HLB. While growers can’t make up …
Despite declaring there will be no silver bullet for HLB, Ozgur Batuman in a Jan. 21 virtual seminar said growers using integrated pest management (IPM) tools “can stay productive.” However, the University of Florida Institute of Food and Agricultural Sciences associate professor also warned that producing citrus juice in Florida “will not be easy or cheap.” Oranges are by far …
In the latest All In For Citrus podcast, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, discussed a statewide citrus workshop hosted at the Southwest Florida Research and Education Center in January. The event provided a day full of educational presentations covering a wide range of topics. Rogers …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a statewide citrus grower workshop in mid-January at the Southwest Florida Research and Education Center in Immokalee. The event offered a full day of education covering a wide range of topics, including management of pests, diseases, weeds and nutrients. Ute Albrecht, UF/IFAS associate professor of plant physiology, provided …
Sponsored Content Question: Are there any updates on the performance of ReMedium TI® and citrus yield improvements? Answer: We are hearing from growers about groves in central and southern Florida where they are observing HLB recovery. I am getting reports from growers that have been steadfast users of ReMedium TI® that seem to be in agreement with much of the …
By Lauren Fessler Mathews, Ana Redondo and Ozgur Batuman Trunk injections of oxytetracycline (OTC) have been proven to give huanglongbing (HLB)-affected citrus in Florida a boost in productivity and quality. However, previous studies have shown that even just six hours of exposure to heat and humidity in the grove can lead to OTC injections that no longer adequately suppress CLas …
By Fernando Alferez, Divya Aryal and Saoussen Ben Abdallah University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research in the last three years has found that the combined use of individual protective covers (IPCs) and brassinosteroids (BRs) enhances protection of citrus trees against HLB and other diseases that limit citrus production in Florida. The research has been conducted …
The U.S. Department of Agriculture (USDA) recently issued a directive about its research and development priorities. The priorities, which cite citrus greening in item 3, are: 1. INCREASING PROFITABILITY OF FARMERS AND RANCHERS While research to increase productivity has allowed American farmers and ranchers to provide the safest, most abundant and most affordable food and fiber supply, the volatility in …
Brazil’s Fundecitrus recently published a scientific article explaining why HLB is so difficult to control. “Why is it so difficult to control huanglongbing (HLB)? Point of view” was published by the journal Scientia Agricola (Agricultural Science). It was authored by Fundecitrus researcher Renato Bassanezi and post-doctoral researcher Isabela Vescove Primiano, in collaboration with the late professor Armando Bergamin Filho of …
By Michael Rogers It has now been two decades since huanglongbing (HLB), or citrus greening, was first detected in Florida. That announcement in August 2005 changed everything for the Florida citrus industry. At the time, Florida citrus was still a global powerhouse. Less than a year earlier, HLB had been confirmed in Brazil, and we were aware of its devastating …
By Jawwad A. Qureshi In winter, citrus trees enter a state of quiescence due to lower light and cooler temperatures, which slows their metabolic activity. Therefore, most citrus trees do not produce new shoots during this period. These young shoots are essential for the growth of the Asian citrus psyllid (ACP), Diaphorina citri. The ACP is a small sap-feeding insect …
Mountain Valley MD Holdings Inc. (MVMD) recently reported positive results from ongoing citrus field trials in Brazil for its Agrarius™ signaling technology. Agrarius™ is designed to organically increase crop yields, reduce fertilizer and pesticide usage and enhance plant health. MVMD has been working with a client-directed third-party agricultural partner, FARM ATAC, in Brazil to assess the impact of the application …
Fundecitrus recently held an international seminar dedicated to citrus greening. The event had approximately 150 participants and featured experts from China and Brazil. GENOME EDITING Xuefeng Wang, from China’s Southwest University’s Citrus Research Institute, highlighted his interest in building a solid partnership in the area of genome editing. He said his group has already identified promising genes that can contribute …
As the end of the year approaches, now is a good time to look back at what has been learned about huanglongbing (HLB) disease over the last 20 years. In the Citrus Industry section of the December issue of Specialty Crop Grower, Michael Rogers, Citrus Research and Education Center director, provides a comprehensive review of the progress made in fighting …
Sponsored Content Question: Are third-party research trials showing good improvement in HLB symptoms with the use of ReMedium TI®? Answer: There have been a number of research trials performed by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) over the past couple of years. ReMedium TI® results have been …
The first half of November saw the most sprouting ever observed in Brazilian citrus by the Psyllid Alert, reaching 37.4%. This scenario raises an alarm for citrus growers, since the increase in sprouting is directly linked to the growth of the psyllid population, the insect vector of huanglongbing (HLB) disease. HLB is also known as citrus greening. According to the …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) citrus breeding team hosted a field day on Nov. 19 at the UF/IFAS Eagle Lake Block. The Eagle Lake Block is a 30-acre property that was gifted to CREC as part of the Jim Hughes estate. The grove tour featured several selections being …
A University of Connecticut researcher recently made advancements in citrus gene editing techniques to reduce the drawbacks of traditional methods. The researcher is Yi Li, professor of horticultural plant breeding biotechnology in the College of Agriculture, Health and Natural Resources. BACKGROUND Scientists employ genome-editing technologies to precisely modify a plant’s own genes, either by inactivating or activating specific target genes …
