Penn State and U.S. Department of Agriculture (USDA) scientists have used cutting-edge CRISPR/Cas technology to develop a diagnostic test that could enable early diagnosis of huanglongbing (HLB). In a study newly published in the journal Phytopathology, the researchers demonstrated that the new test can detect the presence of the HLB causal agent — the bacterium Candidatus Liberibacter asiaticus (CLas) — …
An extract from orange juice production is offering an eco-friendly way for developing transparent wood, an innovative structural material for building construction. Since it was first introduced in 2016, transparent wood has been developed by researchers at KTH Royal Institute of Technology in Sweden. The wood lets natural light through and can store thermal energy. The key to making …
It may not officially be summer yet, but with temperatures heating up, Steve Johnson, chairman of the Florida Citrus Commission, has a reminder about the value of drinking orange juice (OJ) for hydration. “A glass of orange juice is a great hydration option in addition to water since it naturally contains a high percentage of water — almost 90%, says …
Hardee County, Florida, orange grower Kenny Sanders saw his orange production dip in the 2020-21 season compared to the prior year. However, he still made a good profit, thanks to strong fruit prices. “I went down from 400 boxes an acre to 308 boxes, which I can live with, but it’s not as nice,” Sanders said. “We had a good …
A group of scientists working in California, New York and Washington has found that Lisbon lemon trees had less of a molecular response than Washington navel orange trees to the pathogen that causes HLB. That pathogen is Candidatus Liberibacter asiaticus (CLas). In part, this might be because leaves of infected lemons tended to accumulate micronutrients, which led to less of …
Beneficial insects could be a citrus grower’s best friend. In a time when producers are applying insecticides to control the Asian citrus psyllid, the vector of citrus greening disease, it’s important to preserve the psyllids’ natural enemies, like lady beetles and lacewings. Jawwad Qureshi, University of Florida entomologist, implores growers to scout their groves periodically to see what insects are …
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 …
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 …
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 …
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,” …
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 …
Alico, Inc. reported net income of approximately $8.7 million and earnings of $1.16 per share for the six-month period ending March 31, 2021. That’s about double the net income of approximately $4.4 million and earnings of 58 cents per share in the same period of the prior year. The increase in net income is primarily due to greater revenue generated from the Alico Citrus segment. The greater …
An experimental grapefruit grove that graduate student Martin Zapien planted in Florida’s Indian River region is expected to help local growers with future planting decisions. The 20-acre grove with more than 5,000 trees is at the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Indian River Research and Education Center (IRREC). The 1- to 2-year-old trees are new …
