News for citrus growers around the globe
Frequent irrigation with good quality water can improve fruit growth and development and overall productivity. By Tripti Vashisth HLB-affected citrus trees have small and weak root systems. Though the roots are efficient in taking up water and nutrients, there are not sufficient roots to support the tree’s canopy requirement. Therefore, the trees often experience water and nutrient deficit. Not all …
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 …
New research affirms a unique stable antimicrobial peptide (SAMP) found in an Australian plant can destroy HLB and help prevent infection. Hailing Jin, University of California Riverisde geneticist who led the research, shared the exciting discovery during the 2021 Florida Citrus Show. The naturally occurring peptide is found in HLB-tolerant citrus relatives, such as the Australian finger lime. The peptide …
A researcher at the Agricultural University of Athens (AUA) in Greece is using unmanned aerial vehicles (UAVs) to estimate crop yield. “Crop yield is the most important piece of information for crop management in precision agriculture. Early crop yield estimations allow farmers to optimize farm operation scheduling, field management and product marketing decisions,” said AUA associate professor Spyros Fountas. Fountas …
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 …
Amid arguments about the troubled citrus industry and the health of farmworkers, a chemical company is challenging a state decision to block aldicarb, a pesticide that could help fight citrus greening disease. AgLogic Chemical, LLC filed an administrative challenge on May 11, about three weeks after the Florida Department of Agriculture and Consumer Services (FDACS) denied an application to use …
By Francisco Seva Rivadulla The Mexican lemon sector is betting on the diversification of international markets and has its sights set on the Asian market. Oliver Huesmann, director of Fruit Consulting and expert in the Asian market, says lemons have possibilities in all Asian countries. “What is needed is a promotion of this Mexican product so that the consumer knows …
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 …
Companies spend a lot of time developing product labels. “The companies that make the crop protection products work very hard to make them right,” Valent USA’s Senior Field R&D Scientist Craig Campbell said. “I work on labels. They are there as the most important guide for a grower, an applicator or anyone using a pesticide.” In the latest episode of …
Monitoring tree nutrient content via sap analysis is a fairly new concept in Florida citrus, but has at least a decades-long history in other crops. That history and other background information about the technique were addressed in a recent University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) virtual seminar. The workshop’s purpose was to introduce Florida’s citrus growers …
“When a tree gets infected, there is generally no way to cure it,” University of Maryland virologist Anne Simon wrote in a recent white paper about invasive tree diseases. She explained that trees lack adaptive immune systems, so once infected they typically must tolerate the pathogen for the remainder of their lifespan. “In some cases, immunity can be provided by …
By Lauren Diepenbrock Lebbeck mealybugs (Nipaecoccus viridis) have quickly made an impact on citrus groves in Central and South Florida since the pest was first found in 2019. While management techniques are still being studied, this article describes actions growers can take to find this pest before it becomes a problem. SOOTY MOLDLebbeck mealybugs excrete sugary honeydew, much like many …
Citrus acreage is expanding across South Georgia and North Florida. But those interested in planting more acres may have to wait years to receive trees from nurseries, says Jake Price, University of Georgia Lowndes County Extension coordinator. “If you’re wanting a tree now, it’s probably going to be 2023. If you had ordered it six months ago, it might have …
Fruit drop, drought, fruit quality, production costs, deer and Diaprepes root weevil were among problems that bothered Peace River Valley Citrus Growers Association (PRVCGA) members in the 2020-21 season. Those were the issues raised by panelists at a PRVCGA grower roundtable luncheon on May 4 in Hardee County, Florida. “The fruit drop has been the biggest problem this year,” …
Interest in citrus continues to spike in North Florida and South Georgia. Georgia acreage has doubled over the past year. North Florida acreage has increased by another 300 to 400 this spring, says grower Kim Jones. He owns a citrus packing facility in Monticello, Florida, and is president of the Cold Hardy Citrus Association. “We’re seeing a whole lot of …
By Yiannis Ampatzidis Artificial intelligence (AI) is a promising area in computer science, automation, robotics and agriculture. AI describes the capability of a machine to imitate intelligent human behavior and mimic cognitive functions such as learning and problem-solving. Machine learning, which is an application of AI, is based on the idea that a machine, such as a computer or microcontroller, …
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 …
California Citrus Mutual (CCM) is offering agricultural scholarships to high school and college students looking to pursue careers in the industry. Over the last 25 years, the CCM Scholarship Foundation has awarded a total of $80,000 to 59 students. Casey Creamer, CCM president and CEO, said that supporting the next generation of agriculturalists is crucial for overall industry longevity. Having …
