A historical perspective and current conditions are key to understanding what will happen to the orange juice market in the future if HLB-resistant trees are introduced. By Allen Morris Between 2001–02 and 2016–17, the Nielsen-measured retail U.S. orange juice market declined by 50 percent, Florida orange production declined by 70 percent and retail orange juice prices increased by 53 percent …
By Fritz M. Roka The number of H-2A foreign guest workers employed in Florida’s agricultural operations has grown from 4,400 in 2009 to nearly 23,000 by the start of the 2015 citrus harvesting season, more than a five-fold increase (Figure 1). More H-2A workers came to Florida in 2015 than to any other state. Industry leaders estimate that more than …
Echoing comments from growers in some citrus-growing regions in southern Florida, Highlands County citrus Extension agent Laurie Hurner says Highlands County appears to have more fruit and better tree health this year. “It’s interesting. You drive up and down Highway 27, and there is a lot more fruit out there, I think,” says Hurner, who is also the Highlands County …
DeSoto County grower and Florida Citrus Commissioner V.C. Hollingsworth reacts to news that Florida’s citrus acreage declined 5 percent this year. “That kind of surprised me a little bit because I thought we’ve been planting back a lot of trees,” Hollingsworth says. “I think what it doesn’t show is the number of trees that we’re planting back, trees per acre. …
By Nabil Killiny and Steve Futch Citrus growers frequently inquire if Florida temperatures in the summer or winter are sufficiently high or low enough to control or suppress the Asian citrus psyllid (ACP). This question is the subject of this short article. The reason growers pose the question about how temperature impacts psyllids is because ACP is a phloem feeder …
By Marcos Fava Neves The first forecast of the 2017–18 Brazilian orange crop was published in May. Brazil expects a total of 364.47 million boxes, including the following: 68.49 million boxes of Hamlin, Westin and Rubi varieties 17.42 million boxes of Valencia Americana, Valencia Argentina, Seleta and Pineapple varieties 114.52 million boxes of the Pera Rio variety 123.04 million boxes …
At a recent meeting of the Citrus Research and Development Foundation’s (CRDF) Commercial Product Delivery Committee, approximately half of the agenda was devoted to bactericides and HLB-spreading psyllids. Reflective mulch that keeps psyllids away and field trials for HLB-resistant or tolerant rootstocks and scions were also addressed. CRDF Chief Operations Officer Harold Browning summarizes some of the discussions. “The issue …
A new effort is underway in California to further regulate chlorpyrifos. On August 18, the California Department of Pesticide Regulation (DPR) issued a directive for interim mitigation measures to address health risks from the pesticide. This action marks the start of a public and scientific review of DPR’s revised draft risk assessment that could lead to increased restrictions statewide. At …
Lee Jones was in the Citrus Expo seminar audience recently when a scientist reported there have been incidences of HLB-spreading psyllids being resistant to insecticides. Jones, general manager of Gardinier Florida Citrus, has one recommendation for dealing with the issue, at least partially. “I would really suggest that October to March window as an application window for the imidacloprids (a …
Ears perked up in the Citrus Expo seminar hall last week when Lukasz Stelinski reported incidences of Asian citrus pysllid resistance to insecticides, “particularly the neonicotinoid group of insecticides in Florida.” The neonicotinoids have been a key weapon against the psyllids that have spread HLB to groves statewide. Stelinski, an entomologist with the University of Florida’s Institute of Food and …
We first told you last week that the Citrus Research and Development Foundation (CRDF) and Bayer CropScience had announced a new partnership during Citrus Expo to fight citrus greening. Various solutions are being researched, like genetically improved trees. But CRDF President Tom Jerkins knows help is needed before those trees are ready.

By Ute Albrecht Tolerance to a disease is generally defined as the ability to be productive in the presence of disease-causing organisms. This is contrary to resistance, which is defined as the ability to completely evade a pathogen due to specific resistance mechanisms. The question as to what defines an HLB-“tolerant” rootstock was posed in an article by Bill Castle, …
University of California (UC) scientists at the Lindcove Research and Extension Center (LREC) will soon begin to test the effect of growing citrus under protective screen (CUPS). CUPS is a proposed new method of controlling huanglongbing (HLB), or citrus greening disease, by keeping psyllids, small insects known to spread the disease, away from the trees. The test will evaluate the …
Some of Florida’s “best” citrus growers recently told Citrus Research and Development Foundation (CRDF) researcher Jim Syvertsen how they try to cope with HLB. There was much agreement among the growers on fertilization, irrigation, the management of psyllids that spread HLB, and bactericides that have been used against HLB for more than a year. Syvertsen says a survey conducted …
By Jaci Schreckengost Due to the rapid rate huanglongbing (HLB) has affected citrus, researchers are working on new management techniques for the disease. Rhuanito “Johnny” Ferrarezi, assistant professor in citrus horticulture at the University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC), says research is being done to answer questions about how HLB …
By Jude W. Grosser and Frederick G. Gmitter It’s no secret that citrus greening disease, or HLB, continues to take a heavy toll on the beloved Florida citrus industry. It has been estimated that the industry will need to replant over 3 million trees per year for the next 10 years just to get back to normal. So the million-dollar …
The vast diversity of organisms in soil can have positive impacts on citrus, Sarah Strauss told growers and others at a July seminar in Immokalee. “Potentially, though we haven’t verified this, (there are) up to a billion organisms in one gram of soil underneath a citrus tree,” the University of Florida/Institute of Food and Agricultural Sciences soil microbiologist says. “A …
By Jaci Shreckengost The H-2A program is a guest-worker program that allows people from other countries to come to the United States on a visa as agricultural employees for temporary, seasonal work. Many industries are beginning to use H-2A due to uncertainty over the domestic labor supply, says Fritz Roka, an associate professor of agriculture economics at the University of …
By Harold Browning Column sponsored by the Citrus Research and Development Foundation As we start the new fiscal year at the Citrus Research and Development Foundation (CRDF), there are a number of priority activities in place to focus effort and resources on important tools for managing citrus in the presence of HLB. Here are some highlights. Currently, CRDF is sponsoring …
University of Florida/Institute of Food and Agricultural Sciences plant breeder Jude Grosser makes a case for Florida’s citrus industry replacing Hamlin oranges with early-maturing Valencia oranges that he and others are developing. “I think that’s a no-brainer because Hamlins are having a really bad time with greening, and orange juice sales are declining,” Grosser says. “Hamlin is half our juice. …
