LAKE ALFRED, Fla. — Researchers with the University of Florida and several other institutions have found a way in laboratory tests to use 200 times less insecticide and yet still kill as many insects that carry the devastating citrus greening bacterium.
It is a step forward in ridding groves of the insect that is threatening to destroy Florida’s $10.7 billion citrus industry. (more …)
GAINESVILLE, Fla. — What’s a little pesticide among neighbors? For Florida citrus growers, it could mean saving their trees that are under attack from the virulent citrus greening bacterium threatening to destroy the state’s $10.7 billion industry.
Entomologist Michael Rogers, director of the University of Florida’s Citrus Research and Education Center, is telling growers that one of the best approaches to managing citrus greening is to control the insect that spreads this disease. And the best way to do that is by coordinating their pesticide applications with their neighbors. (more …)

GAINESVILLE, Fla. — The Florida Citrus Rootstock Selection Guide is now online at http://flrootstockselectionguide.org in a format that lets visitors interact with the guide.
Visitors to the site can find 104 publications supporting the ratings in the guide and can conduct queries of the rootstock information, said Stephen Futch, UF/IFAS multi-county Extension agent. The information and tools let you make informed citrus rootstock selections for your groves.
Three large buttons on the home page let you:
- Open and interact with the Rootstock Selection Guide. It presents information on 45 rootstocks and 20 traits.
- Open the Consult Guide, which introduces new technology to help you arrive at the best rootstock recommendations for your circumstances.
- Open the Learn section, which contains a bibliography of references in an easy to use database with more than 100 published articles.
To access the website, go to www.crec.ifas.ufl.edu, then click on “Extension,” then “Horticulture,” then “Varieties and Rootstocks.”

As citrus greening continues to impact Florida’s groves, growers have found that they need a way to quickly and accurately count the amount of fruit dropped early to help identify problem areas, which will save time and money.
University of Florida researchers Wonsuk “Daniel” Lee, Daeun “Dana” Choi, Reza Ehsani and Fritz Roka devised a “machine vision system” to count citrus fruit that has dropped early. The device is suitable for various conditions in citrus groves, including addressing problems of variable lighting, giving accurate estimates of dropped fruit counts and providing exact locations of trees with greater fruit drop, indicating a problem area.

LAKE ALFRED, Fla. — The disease that threatens to destroy Florida’s $10.7 billion citrus industry appears to have its own mechanism to promote its spread, making it harder to control. A recent study by five University of Florida researchers shows Asian citrus psyllids fly earlier in their life cycles, more frequently and farther when they are infected with citrus greening bacterium.
Kirsten Pelz-Stelinski and the team of researchers at UF’s Institute of Food and Agricultural Sciences’ Citrus Research and Education Center in Lake Alfred say these conclusions have global implications for how the disease spreads and strategies to control it. (more …)

GAINESVILLE, Fla. — The 3rd edition of the Florida Citrus Rootstock Selection Guide is now available. The updated guide is a convenient, easy-to-use reference to 20 characteristics of 45 rootstocks. It highlights 21 recently released rootstocks, some of which show reduced citrus greening incidence in early field trials.
Of the 45 rootstocks, 12 are time-honored commercial ones, 12 are minor commercial ones that are less frequently used but may have been prominent once. The third group is the most recently released rootstocks for which there is limited commercial experience, but are increasingly being used in the Florida citrus industry.
The revised guide is important because rootstocks basically provide the root system of a citrus tree and influence many traits of the whole plant. When a Valencia orange or Marsh grapefruit is grafted to the rootstock seedling, such things as tree size, fruit quantity and quality are usually improved by the rootstock.
LAKE ALFRED, Fla. — One of the University of Florida’s newest professors, Yu Wang, came all the way from Mars to work as a flavor researcher with the Institute of Food and Agricultural Sciences.
Mars, Incorporated, that is – the same folks who bring us the chocolate treats M&Ms, Dove and Twix Bars. (more …)

GAINESVILLE, Fla. — As the University of Florida prepares to embark on the 2015-16 academic year, the College of Agricultural and Life Sciences offers several courses and majors that reflect how the institution adapts to industry and stakeholder needs.
The courses and majors aren’t brand new for this fall. They evolved during the past few years. But they reflect the growing menu of courses and majors offered to the more than 3,700 undergraduate students expected to enroll at UF CALS this fall.
Just to name a few of the relatively new majors and course offerings, UF CALS offers a major in marine sciences that leads to a bachelor’s degree, a new undergraduate certificate titled “Challenge 2050: Global Leadership and Change” from the Challenge 2050 Project and three new majors offered in the Food Science and Human Nutrition Department that were previously specializations under one major – Food Science and Human Nutrition.

GAINESVILLE, Fla. — A $1 million University of Florida research project to fight citrus greening got the green light in the state’s budget.
Nian Wang, a researcher with UF’s Institute of Food and Agricultural Sciences, is working with a team to develop a microbial-based product, infused with patented plant-defense inducers and beneficial bacteria strains, that he hopes will cure citrus greening. (more …)
GAINESVILLE, Fla. — Florida has nearly 70 million citrus trees on more than 531,500 acres. Now imagine trying to figure out what pesticide to spray on each of those trees to keep them safe from citrus greening.
University of Florida researcher James Tansey says the answer is as close as your Android smartphone with a new app developed with ZedX, an information technologies company based in Pennsylvania. The free phone program allows citrus farmers to enter in about a dozen variables — like the type of crop, insect pressure, harvest date, previous spray history, and whether the crop will be for fresh fruit or juice and for export or domestic markets — to determine the best pesticide to use. There are also record-keeping options, and the app keeps track of sites with gps. (more …)
