(NSF) — The Department of Agriculture and Consumer Services wants the Florida Supreme Court to put on hold a legal battle about payments to Lee County homeowners whose healthy citrus trees were cut down amid an effort to halt the spread of citrus-canker disease. The department on Wednesday filed a motion for a stay, after taking the long-running case to the Supreme Court last …
The Senate passed an appropriations minibus package that included critical funds for Florida secured by Senator Rubio (H.R 3055, Commerce, Justice, Science, Agriculture, Rural Development, Food and Drug Administration, Interior, Environment, Transportation, and Housing and Urban Development Appropriations Act of 2020). In his role on the Senate Appropriations Committee, Senator Rubio secured major funds for Florida’s citrus industry: $8.5 million …
Laurie Hurner grew up in a fifth-generation Florida citrus-growing family, and she and her sisters worked their farm in Highlands County. “My parents had three daughters,” said Hurner, the director of University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension Highlands County and the county’s citrus agent. “We were all well-rounded.” From their mom, the girls learned what …
Since 2016, federal authorities have allowed Florida citrus growers to spray oxytetracycline solutions on their trees to combat citrus greening disease. A newly published University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study suggests that the bactericide would be more effective if it were injected into citrus tree trunks, a practice not currently approved under U.S. law. Citrus …
While citrus growers continue to look for best management approaches to deal with the deadly greening disease, scientists will take an integrated look at how to protect young trees by using existing tools growers can use. Five scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will compare insect management tools, including insect-proof netting. Researchers also …
After serving nearly 10 years as the senior vice president for agriculture and natural resources with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), Jack Payne announced he will retire next year. His last day with UF/IFAS will be July 1, 2020. Payne has overseen Extension offices across Florida and its 12 research and education centers since …
Precision agriculture engineer Yiannis Ampatzidis sees a day when citrus farmers use artificial intelligence (AI) to detect the pin-sized insects that can infect the fruit’s trees with the deadly greening disease. That day could come in the near future, because Ampatzidis and his research team are starting to perfect a system to detect the potentially deadly Asian citrus psyllid. Citrus …
Growers of one of Florida’s signature citrus crops may see more production and possibly less of the deadly citrus greening disease. Researchers have worked for four years growing grapefruit under protective screens on a 1-acre experimental plot at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), and they’re seeing encouraging results. UF/IFAS scientists and a few commercial …
The California Department of Food and Agriculture (CDFA), working in cooperation with the Sacramento County agricultural commissioner, has placed Sacramento County under a plant pest quarantine for the Asian citrus psyllid (ACP) following the detection of one ACP in Sacramento’s Lemon Hill area. The quarantine prohibits the movement of citrus and curry leaf tree nursery stock and all plant parts, …
Citrus research continues to be a topic in state and federal funding circles as the industry’s battle with HLB, or citrus greening, continues. One idea in the incubator of industry discussion is the Citrus Research and Field Trial (CRAFT) program. It would involve large-scale grower field trials throughout Florida. Rick Dantzler, chief operating officer of the Citrus Research and Development …
Senate Appropriations Chairman Sen. Ron Bradley supports maintaining the current level of funding for the state’s citrus industry, as a decade of research about combating deadly citrus greening disease is applied more in groves. After hearing presentations Wednesday from citrus-industry leaders, Bradley, R-Fleming Island, said there “certainly” won’t be a drop from this year’s $23.2 million in funding. At the …
Imagine using a robotic arm to grip and puncture the trunk of a citrus tree to deliver chemicals into the vascular parts of the plant, reducing its susceptibility to the citrus greening disease. Ozgur Batuman, an assistant professor of plant pathology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), leads a team of researchers trying to …
When Nian Wang pieces together sequences of genes, he hopes to make citrus varieties that are more tolerant to the deadly disease known as citrus greening, which has devastated a multibillion-dollar-a-year industry in Florida. Wang, a professor of microbiology and cell science with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), will help an investigation in which …
Results show promise for organic groves, but more research is needed. Since it was first discovered in the United States in 2005, the bacterial disease known as citrus greening, or Huanglongbing, has devastated millions of acres of citrus crops throughout this country and abroad, ravaging citrus groves in Asia, Africa and South America. Citrus greening has impacted conventional and organic …
Citrus growers can learn more about managing Asian citrus psyllids and other pests in a workshop Jan. 8 at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC). The psyllid can transmit the bacteria associated with greening disease to citrus trees and has already caused severe damage to Florida’s multi-billion-dollar-a-year citrus industry. …
Florida citrus growers have begun taking notice of kaolin clay, a powdery white compound, because it can cause Asian citrus psyllids (ACP) to “not take notice” of their groves. Long used to protect other fruit and vegetable crops, kaolin can also conceal citrus trees from hungry psyllids by confusing their visual sensory system, said Michael Rogers, director of the Citrus …
Florida’s grapefruit industry, devastated by citrus greening, may find hope in four ½-acre white-mesh screenhouses in a research field in Fort Pierce. The project will be funded by a $3.5 million grant from the U.S. Department of Agriculture (USDA) awarded to the University of Florida. Studies for the grant will take place inside and outside these structures, where 512 young …
A University of Florida (UF) scientist hopes to improve on laser technology to enhance the efficiency of spray solutions aimed at restoring vitality to greening-affected citrus trees and reducing amounts of chemicals applied. With the updated technology, a laser shoots infra-red energy pulses at citrus tree leaves, said Ed Etxeberria, a professor of horticultural sciences at the UF Institute of …
By Brian German A series of strategic planning sessions have helped to craft a more detail-oriented approach to address the spread of Asian citrus psyllid (ACP) and management of huanglongbing (HLB) detections. As of Oct. 9, there have been 906 positive HLB detections in California. “The real hot spot for us right now is Orange County. We’re finding a lot of HLB-positive …
Mature citrus trees affected by the bacterial disease huanglongbing (HLB) typically need about 25 percent less irrigation than their healthy counterparts However, that doesn’t necessarily mean young trees with the disease will benefit from water deficits, according to a preliminary greenhouse study by researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Experiments on 1-year-old orange …
