By Ute Albrecht and Leigh Archer Trunk injection is a targeted delivery of materials into the stem or trunk of trees as an alternative to spraying or soil drenching. It is practical for disease and pest management in high-value forest trees and ornamental plants where aerial applications are problematic because of environmental and human health-related concerns. Interest in using the …
Citrus researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are taking a more comprehensive look at how tools to manage HLB affect young trees. The goal is to develop integrated approaches and update management practices for growers. After one year of the research project, some interesting results are already emerging. The research project, “Establishing Healthy …
Florida citrus growers may have a new tool to help them slow the presence of HLB in already diseased trees, courtesy of researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The researchers found that injecting a benign Xylella fastidiosa EB92-1 bacteria biocontrol into infected citrus trees over a period of six years reduced the incidence …
Reductions in the projected Florida grapefruit and tangerine/tangelo crops were the only changes in the May 12 U.S. Department of Agriculture (USDA) citrus crop forecast. USDA’s National Agricultural Statistics Service (NASS) reduced Florida’s grapefruit crop projection by 2%, to 4.2 million boxes, down from 4.3 million boxes in April. The total 100,000-box reduction was in red grapefruit, which dipped to …
Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are taking a whole-systems approach to update current recommendations for new plantings. A research project, “Establishing Healthy Citrus Plantings in the Face of Persistent HLB Pressure,” is led by UF/IFAS entomologist Lauren Diepenbrock. According to Diepenbrock, current guidelines were created pre-HLB and therefore are out of date …
Thomas “Tom” James, citrus horticulture research operations manager at the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Indian River Research and Education Center (IRREC), recently received a UF/IFAS Superior Accomplishment Award. At the IRREC, James facilitates a team of 17 visiting scientists, agricultural assistants and interns who perform field activities in two citrus groves on university property …
A team of University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers is investigating how changes in soil health impact citrus and other subtropical tree crops. Specifically, they will examine how quickly soil health can change in Florida and how specific changes might impact yield. The U.S. Department of Agriculture National Institute of Food and Agriculture is funding …
Indian River area citrus grower Cody Estes provided the impetus for an upcoming research project into the use of sap analysis for monitoring citrus tree nutrient levels. The analysis method has been used in other crops. Advocates declare it to be a relatively inexpensive way to quickly determine nutrient status so growers can make corrections before nutrient excess or deficiency …
“We’ve come a long way in the time that we’ve had HLB here in Florida,” says Michael Rogers. The director of the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center says early HLB research “covered a wide range of topics.” Now, however, “We’re really narrowing down things that are of use to growers …
Scientists from the University of Granada (UGR) have made the first anatomical atlas of the Asian citrus psyllid (ACP), which spreads HLB. The research group, led by Professor Susan J. Brown from Kansas State University, conducted a multidisciplinary project to study the psyllid, the bacteria it transmits, its effects and means of control. The U.S. research team approached Javier Alba-Tercedor …
The Citrus Research and Development Foundation (CRDF) received 59 proposals for funding of projects in response to the organization’s recent request for proposals (RFP). “This is the best RFP we’ve ever done since I’ve been here,” said CRDF Chief Operating Officer Rick Dantzler. The deadline for submitting proposals was April 26, a day before the CRDF’s board of directors …
A whole-systems approach to one University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research project is the focus of the April All in For Citrus podcast. Citrus Research and Education Center Director Michael Rogers said the project is a good example of citrus researchers taking a more comprehensive look at problems in the industry. “We’re starting to put …
University of Maryland virologist Anne Simon and the company she founded, Silvec Biologics, have successfully vaccinated laboratory hosts against citrus tristeza virus (CTV). They are now focusing on HLB, also called citrus greening. The vaccination induces trees to produce their own therapeutic agents. Silvec’s vaccination concept is based on the discovery of a novel infectious RNA that the company calls …
Colorado State University (CSU) researchers are predicting an above-average Atlantic hurricane season in 2021, citing the likely absence of El Niño as a primary factor. Tropical Atlantic sea surface temperatures are near their long-term averages, while subtropical Atlantic sea surface temperatures are much warmer than their long-term average values. The warmer subtropical Atlantic also favors an active 2021 Atlantic hurricane …
Parasitic nematode damage in agriculture totals $125 billion around the world each year. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers hope to alleviate some of that destruction. The UF/IFAS scientists will use artificial intelligence (AI) to try to more rapidly identify nematodes. Some nematodes live in the ground and harm plants, while others are beneficial, so …
Proper irrigation and nutrient management are necessary to maximize root density and tree health, especially in trees infected with HLB. Davie Kadyampakeni, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, shared a few irrigation and nutrient research updates during the March episode of the All In For Citrus podcast. IRRIGATION RECOMMENDATIONS Young citrus trees require optimal …
Florida’s Valencia orange crop projection tumbled 12% in the April 9 U.S. Department of Agriculture (USDA) crop forecast, to 29 million boxes from 33 million boxes in March. The USDA added 200,000 boxes, or 1%, to Florida’s non-Valencia tally, bringing non-Valencias to 22.7 million boxes. In total, Florida oranges dipped to 51.7 million boxes, down 7% from March’s 55.5 million …
Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are using RNA interference (RNAi) to alter field populations of the Asian citrus psyllid (ACP). Nabil Killiny, UF/IFAS associate professor, shared the latest findings from his team’s RNAi research in a recent All In For Citrus podcast episode. He says the team is using RNAi to attack …
The response rate in Florida has been lower than expected in an effort to assess the impact of the COVID-19 pandemic on food and agricultural systems and to develop strategies for coping with future crises. Consequently, those involved in Florida agriculture are being asked to respond by April 11 to a survey about the pandemic’s impact. “We’re seeking food supply …
Agricultural best management practices (BMPs) are essential to protect Florida’s natural resources by mitigating agriculture’s potential negative impact on the environment. Public benefits of BMP implementation include sustained or improved water quality, reduced soil erosion and increased water conservation. Private benefits can include improved crop yield and reduced input costs from less labor, fuel and fertilizer. “Growers provide a public …
