Citrus growers from several of Florida’s production regions joined researchers recently for a look inside 14-foot high screenhouses that protect trees from HLB-spreading Asian citrus psyllids. The CUPS (Citrus Under Protective Screens) Field Day took place at the University of Florida Institute of Food and Agricultural Sciences Indian River Research and Education Center (UF/IFAS IRREC) in Fort Pierce. Johnny Ferrarezi, …
An update on the nutrition box program, shade research with some positive side effects, and a bold project analyzing compounds used against HLB headline January’s All In For Citrus podcast. The Citrus Nutrient Management Program, more commonly known as the nutrition box program, is over a year old. Citrus Research and Education Center Director Michael Rogers, with the University of …
Ongoing citrus rootstock trials being conducted by University of Georgia (UGA) Cooperative Extension in Lowndes County hold promise for increased yields, improved fruit quality and greater disease resistance. Jake Price, UGA Extension agent and Lowndes County Extension coordinator, has six local citrus rootstock/variety trials with varying objectives. The trees are custom-produced by U.S. Department of Agriculture (USDA)-certified citrus nurseries in …
Phytophthora and leprosis diseases can each substantially reduce productivity of a citrus tree, but when they attack trees already weakened by HLB, the result can be fatal. Ozgur Batuman, assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), explained how co-infection impacts HLB-infected trees during a recent UF/IFAS webinar. PHYTOPHTHORA DISEASESPhytophthora species are soil-borne fungal pathogens …
Like several commercial Florida citrus growers, Ben Bateman of Brandon has noticed strong improvement in what he calls his “recreational grove” after applying oak mulch to the trees. Bateman planted 26 mixed-variety trees in large pots about six years ago, transplanting them to the ground five years ago. He said he spent nearly $1,000 on foliar nutrients “with little to …

By Jawwad Qureshi Several studies have documented the positive effects of controlling the Asian citrus psyllid (ACP, Figure 1) for citrus tree health and sustainability in Florida. The mature blocks established before and after the discovery of huanglongbing (HLB) in 2005 continue to benefit from psyllid control. One psyllid is enough to infect a tree with HLB for life, and …
By Lauren Diepenbrock Pest management is an ongoing effort in Florida citrus. Taking advantage of pest life cycles, whether they are tied to the season or plant phenology, can make management efforts have greater impacts on pest populations. For many citrus growers, managing the impacts of Asian citrus psyllid (ACP), the vector of huanglongbing (HLB), is part of the annual …
Lukas Hallman, a graduate student at the Indian River Research and Education Center (IRREC), is doing research to find what is in oak trees that apparently helps citrus cope with HLB. The University of Florida Institute of Food and Agricultural Sciences operates the IRREC. “Anecdotal reports from Florida growers claim that citrus trees growing within the drip line of large …

She discussed fruit drop during the first presentation of the new UF/IFAS OJ Break meeting …
A company that recently obtained a patent for a natural peptide solution to treat HLB has received Citrus Research and Development Foundation (CRDF) funding to see if the product has efficacy for other citrus diseases. CRDF will fund the company, Elemental Enzymes, for about $61,200, said CRDF Chief Operating Officer Rick Dantzler. Elemental Enzymes proposes to do research “to see …
Numerous Florida citrus growers are experiencing heavy fruit drop this fall. “For some growers, it’s the worst fruit drop they have experienced; 50 percent-plus,” says grower Lee Jones with Cross Covered Caretaking.

Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are looking to increase the efficiency of known Asian citrus psyllid (ACP) control techniques by using them together. The pairing should help control populations of the insect that spreads huanglongbing (HLB) disease. Bryony Bonning, UF/IFAS eminent scholar and entomology professor, is leading the research funded by a …
Researchers looking into the possibility that the old Parson Brown orange might fare better than Hamlins in the face of HLB will be funded by the Citrus Research and Development Foundation (CRDF).
