When the next frost threatens Florida’s crops, growers will do their best to make sure your favorite foods are protected from the potentially crippling chill, say University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) experts. For example, citrus growers use wind machines and microsprinklers to ensure freezing temperatures don’t ruin the fruit, said Chris Oswalt, a multi-county citrus …
By Jawwad Qureshi, Lukasz Stelinski and Fernando Alferez Management of huanglongbing (HLB) has focused on reducing the vector Asian citrus psyllid (ACP) and improving tree health, thus requiring a multi-pronged approach. Several elements of an HLB management system are either available or under current investigation. Maintenance of clean nursery stock, vector management and tree nutrition are widely implemented, while incorporation …
Growers with trees affected by HLB should try to maintain soil pH in the 6 to 6.5 range, Kelly Morgan told numerous growers attending a recent Citrus Nutrition Day event. Morgan is director of the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Southwest Florida Research and Education Center. Morgan explained that soil pH affects trees’ ability to …
Jim Dilley of Dilley Citrus Nursery in Punta Gorda was intrigued by some new varieties he sampled at the Citrus Research and Education Center in Lake Alfred recently. Dilley singled out “several of the tangerines: 1818, 1819” as being of interest to him. “They were easy peel. It was apparent that one of them was probably a little earlier than …
By Megan Dewdney, Evan Johnson, Naweena Thapa and Michelle Danyluk In 2015, we started a large-scale project to determine if thermotherapy would be an effective huanglongbing (HLB) treatment for field trees. Some of the objectives were to determine effective temperature-time combinations for thermotherapy, which season gave optimal results for thermotherapy, and the effect on yield in subsequent years. TRIAL DETAILSComprehensive …
Grower and gift fruit shipper Pete Spyke was among more than 100 people who sampled approximately 50 new University of Florida varieties at the Citrus Research and Education Center on Dec. 4. “There’s some good-tasting, easy-peel, seedless (mandarin) varieties that I think will be working their way through the gauntlet,” said Spyke. He added that several will probably be released …
An agricultural engineer whose current research projects include the simulation of agricultural management impacts on water quantity and quality in the upper Floridan aquifer has joined the University of Florida’s Indian River Research and Education Center (IRREC). Sandra Guzmán will lead the center’s irrigation and hydrology program. Guzmán started her position as an assistant professor of agricultural and biological engineering …
At a recent field day for citrus under protective screen (CUPS) in Polk County, researcher Arnold Schumann discussed varieties that appear to work well in the system. Schumann is with the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center. The primary purpose of growing citrus under protective screen is to keep out the Asian …
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. …
University of California (UC) Davis research scientist Louise Ferguson is taking part in a $3.4 million project titled “Development of an automated delivery system for therapeutic materials to treat HLB-infected citrus.” The study is funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture. The four-year project includes work by researchers at the University of Florida, UC …
By Ernie Neff Jerry Mixon’s use of netting to keep birds from blueberries helped pique his interest in growing citrus under protective screen (CUPS) to exclude HLB-spreading psyllids. But he credits University of Florida researcher Arnold Schumann with helping him bring his Polk County CUPS project to fruition. Mixon met Schumann in 2015, the year after Schumann’s 1-acre CUPS was …
The U.S. Environmental Protection Agency (EPA) has approved an emergency authorization requested by California Citrus Mutual (CCM) to use Evergreen Pro 60-6 (EPA Reg. No. 1021-1770). It was temporarily approved as a post-harvest treatment option for all citrus in California to prevent the spread of Asian citrus psyllids, the vector for huanglongbing. CCM had requested that citrus growers be allowed to use …
By Marcos Fava Neves When compared to last season’s output, expected orange production this season is dramatically different in both Florida and Brazil. FLORIDA UP The U.S. Department of Agriculture’s November forecast for Florida’s 2018–19 orange crop is 77 million boxes, 71 percent more than last season’s 45 million boxes. Of these 77 million boxes of oranges, 32 million boxes …
Growers producing fresh fruit inside the relatively new citrus under protective screen (CUPS) structures in Florida have some unique heat and cold considerations. Chris Oswalt, citrus Extension agent for Polk and Hillsborough counties, spoke on this subject at a recent CUPS field day in Alturas, Florida. “Based on some of the early data that we have from the weather stations …
By Len Wilcox California agriculture has long kept a watchful eye on the spread of HLB (huanglongbing or citrus greening disease). It’s a firestorm on the horizon, and the devastation the disease has wrought in Florida and other parts of the world has the full attention of California citrus growers. Working closely with industry leaders and grower groups, federal, state …
At a lunch meeting in Tallahassee, Florida, with representatives of many of the state’s agricultural organizations, Florida Agriculture Commissioner-Elect Nikki Fried told the group she plans to be a “champion for this industry” in her new role. Several major issues facing Florida agriculture were discussed during the lunch meeting, which was the first meeting of its kind with Fried since …
By Brenda Eubanks Burnette This year, before Halloween was even over I was seeing Christmas decorations. It made me wonder: What happened to Thanksgiving? We used to send Happy Thanksgiving cards and plan big family reunions over Thanksgiving meals with tables loaded with recipes handed down over the years. Now it seems more like an afterthought and “Let’s get our …
By Rhuanito Ferrarezi, Alan Wright and Arnold Schumann High-density plantings have been tested worldwide in advanced citrus production systems (ACPS) to increase efficiency of water, fertilizer and light, and to maximize yield per area. After the onset of huanglongbing (HLB) in Florida, canopy growth reduced drastically due to negative impacts on plant health, creating the need for new plant spacing …
The Asian citrus psyllids (ACP) found last week in a residential area in north Visalia, California, were a breeding population, according to Greg Douhan, University of California Cooperative Extension farm advisor for citrus. The ACP were found in four locations in the city, not in close proximity to any agricultural operations. “Most of the findings found in the San Joaquin Valley …
Until a solution for citrus greening is found, imports will be key to keeping Florida’s citrus industry afloat. Domestic orange production has been declining steadily over the last two decades, with citrus greening disease being the leading cause of decreased acres and productivity. As the gap between domestic production and consumption has widened, imports have increased to boost dwindling domestic …
