Stubby root symptoms on the declining trees suggested damage by sting nematodes (Belonolaimus longicaudatus). This nematode …
By Evan Johnson Diseases caused by phytophthora continually threaten Florida citrus production. Brown rot can directly reduce yields of early maturing varieties including Hamlin and grapefruit, can delay harvest of fresh market fruit until infected fruit have dropped, or risk packinghouse rejection of the load because it can spread post-harvest. Foot and crown rot can kill trees but are uncommon …
Citrus growers discuss production practices to improve root health. By Tacy Callies What began as an experiment in Ben Krupski’s 10-acre grove in Howey-in-the-Hills, Florida, is now a common practice he uses as production manager for Lennon Grove Service. Four years ago, Krupski started testing the use of compost in his small leased block of Hamlin trees. In the first …
The California citrus industry is valued at nearly $3.5 billion with over 3,000 growers farming 320,000 acres throughout the state. The size and scale of citrus production has both direct and indirect effects on California’s overall economy. “If you think about primary production, which citrus is, it requires that the citrus growers buy what’s called ‘intermediate inputs’ or inputs from …
The March issue of Citrus Industry magazine gets to the root of the matter. Several articles cover the topic of root health. Citrus growers Ben Krupski and David Wheeler share successful strategies for stronger roots. Methods include the use of compost, more frequent irrigation and other techniques. Three University of Florida research articles in the March issue also address root-related …

“Unfortunately, there is no silver bullet” for HLB, plant pathologist Ozgur Batuman told growers in Immokalee recently, adding that he doesn’t think there will be one. “The best option for such a complex and challenging disease is … integrated pest management (IPM). And our growers here in Florida are actually doing just that. Now they are paying attention to root …
It’s time to prepare for implementation of the Produce Safety Rule. By Travis Chapin, Michelle Danyluk and Keith Schneider In preparation for implementing the Food Safety Modernization Act’s Produce Safety Rule (PSR), growers, harvesters and packers of fresh citrus are required to attend standardized food-safety training, such as the Produce Safety Alliance (PSA) grower training course, which outlines the minimum …

Marco Rubio implored Florida’s new governor Tuesday to start spreading disaster-relief money approved nearly a year ago to address massive citrus-industry damage from Hurricane Irma in 2017. Rubio said in a letter to Gov. Ron DeSantis that money in a $343 million block grant needs to be disbursed to citrus growers. Rubio said the federal government shutdown has …
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 …
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 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.

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 …
By Marcos Fava Neves When compared to last season’s output, expected orange production this season is dramatically different in both Florida and Brazil.

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 …
This year’s Citrus Nutrition Day — at which growers will learn the latest data about growing the fruit, from the soil up through the plants — is expanding to include tours of field trials.
