GAINESVILLE, Fla. – The citrus industry has just gotten its own state-of-the-art greenhouse, dedicated solely to citrus nursery research as the state continues its fight against citrus greening – and industry and research officials are set to celebrate the gift March 25.
The $200,000 facility is located at the University of Florida’s Mid-Florida Research and Education Center in Apopka. Officials say it was built there to shield the young plants from greening in the state’s main citrus-crowing areas of Central and South Florida, as federal guidelines suggest. (more …)
Shown is coleus cultivar UF12-86-91, recently approved by a UF/IFAS committee. The panel recently approved 13 other cultivars — in coleus and citrus — for release.
GAINESVILLE, Fla. – Fourteen new cultivars, including eight coleus varieties and six citrus, have been approved for release by the University of Florida’s Institute of Food and Agricultural Sciences.
Coleus are used as decorative bedding plants for landscaping, in mixed containers and as indoor potted plants in homes and gardens in North America and throughout the world. They are versatile, consumer-friendly plants because they are easy to grow in sun and shade and require less maintenance than many other garden plants, said David Clark, professor in floriculture and biotechnology, who developed the new cultivars.
GAINESVILLE, Fla. — Researchers from the Institute of Food and Agricultural Sciences at the University of Florida are closer to finding a possible cure for citrus canker after identifying a gene that makes citrus trees susceptible to the bacterial pathogen.
Citrus canker, which causes pustules on fruit, leaves and twigs, is a highly contagious plant disease and spreads rapidly over short distances. Wind-driven rain, overhead irrigation, flooding and human movement can spread citrus canker. Human transport of infected plants or fruit spreads the canker pathogen over longer distances. (more …)
GAINESVILLE, Fla. — Citrus crop-yield estimates may be more accurate, thus ensuring higher productivity and more revenue, if an algorithm proves as successful as it did in a recent University of Florida study.
Wonsuk “Daniel” Lee’s study, published in the January issue of the journal Biosystems Engineering, could eventually help Florida’s $9 billion-a-year citrus industry.
Lee, a UF agricultural and biological engineering professor, used an algorithm to find immature citrus in photos taken under different light conditions and fruit that was hidden by leaves and branches. He and his colleagues found 80 percent of the immature fruit.
GAINESVILLE, Fla. – A University of Florida researcher who helped develop a mathematical model to show how citrus greening spreads within infected trees has received a $300,000 grant from the Esther B. O’Keeffe Foundation to expand the model.
Ariena van Bruggen, a UF plant pathology professor, received the award so she can study the best strategies to combat citrus greening from tree to tree. There is no cure for citrus greening, but methods being used to slow the disease include removal of symptomatic trees, insect control and attempts to boost the tree’s immune system, van Bruggen said.
An Asian citrus psyllid feeds on a citrus tree, leaving the citrus greening bacteria. The bacteria will starve the tree of nutrients and eventually kill it.
GAINESVILLE, Fla. — A University of Florida researcher has mapped the DNA genome of a new strain of citrus greening that could further threaten Florida’s beleaguered $9 billion citrus industry. Knowing the genetic makeup of the various strains is critical to finding a cure.
Dean Gabriel, a plant bacteriology specialist with UF/IFAS, helped sequence and map the genome of the most prevalent form of the disease in Florida, and now he and colleagues have done the same for a new strain of the disease discovered in Brazil. (more …)
GAINESVILLE, Fla. — Food safety is near the top of most Floridians’ concerns, behind only the economy and health care, a survey released today by the University of Florida shows.
The survey covered several food-related issues, including public perceptions about food safety, food insecurity and genetically modified foods. It also found knowledge gaps among Floridians, especially in the area of food safety, and detected conflicted feelings among the public about genetically modified foods. (more …)
GAINESVILLE, Fla. — University of Florida researchers have some encouraging results in the battle against citrus greening.
They have identified citrus cultivars, in this case 16 citrus rootstocks, most of which show a lower rate of infection and more tolerance to citrus greening – the dreaded disease that has wreaked havoc through Florida’s citrus industry since its arrival in the state in 2005.
GAINESVILLE, Fla. — A Polk County architect-turned-citrus grower’s decision to allow researchers to use 100 acres of land has given the University of Florida’s Institute of Food and Agricultural Sciences a much-needed boost in the battle against deadly citrus greening.
Located around Polk County, the donation – a combination of older and recent gifts from grower Jim Hughes, who died earlier this month – increases the UF Citrus Research and Education Center’s available field-trial research space by about 50 percent, said Jackie Burns, the center’s director.
