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 …
Daily irrigation is important in managing HLB-affected trees, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) soil scientist told a Citrus Nutrition Day crowd in Bartow on Dec. 11. The researcher, Davie Kadyampakeni, said daily irrigation reduces tree water stress and improves tree water use. According to Kadyampakeni, keeping water in the top 12 inches of soil …
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. …
At the Dec. 11 Citrus Nutrition Day hosted by the University of Florida Institute of Food and Agricultural Sciences Polk County Extension, two growers shared their experiences with nutrition programs. The citrus growers, James Shinn of Shinn Groves/Tree O’Groves Inc. and Matt Story of the Story Companies, shared their knowledge via video interviews with citrus Extension agent Chris Oswalt. Oswalt …
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 …
A Citrus Nursery Production Guide is expected to be published by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) in five or six months. “We are going to cover the basics of nursery production,” said UF/IFAS researcher Rhuanito (Johnny) Ferrarezi. “Then we will help (with) selecting varieties. We will talk about … how to clean material, how …
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 …
Grower Christian Spinoza of Dudley Putnam, Inc. was among about 30 people who heard proposed federal crop insurance changes at a recent “listening session” in Bartow, Florida.

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 …
An invasive plant, Chinese crown orchid, was recently found in a Highlands County citrus grove, Laurie Hurner reported.
