Kirsten Pelz-Stelinski, a University of Florida/Institute of Food and Agricultural Sciences entomologist, reports on the psyllid control methods that produce the best and worst results: “We looked at abandoned (groves); intermittently managed (groves), which we considered to be five or fewer insecticide sprays per year; we looked at organically managed groves; and we looked at what we called conventionally managed …
The value of bactericides and Asian citrus psyllid control were some of the major issues that growers discussed at a forum in Sebring on May 11. Laurie Hurner, Highlands County Extension director and citrus agent, summarizes the discussions. Hurner reports that one grower will say the bactericides seem to be working against HLB, while another says they see no tree …
Michael Rogers with the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) says growers frequently ask him two questions. One is whether they need to continue to control HLB-spreading Asian citrus psyllids even though HLB is widespread in Florida. The other is about the best time to spray for psyllids. Rogers, an entomologist and director of the UF/IFAS …
Growers shared their frustrations and experiences with HLB at a May 4 grower roundtable meeting in Wauchula. Event co-host Steve Smith, executive director of Peace River Valley Citrus Growers Association, summarizes the discussions. “A lot of the growers were talking about fertigation and how much, and what’s working for them on the short-term basis as far as tree health goes,” …
Tripti Vashisth, a University of Florida/Institute of Food and Agricultural Sciences horticulturist, reports on brassinosteroid and nutrient uptake studies aimed at alleviating HLB symptoms. She reported on these studies at a recent HLB Grower Day summarizing scientific presentations made at an international HLB research conference. The brassinosteroid (a plant growth regulator) study was conducted at the University of Havana in …
Populations of HLB-spreading psyllids in groves can be impacted by windbreaks, grove orientation and whether new plantings are resets or solid settings. So says Kirsten Pelz-Stelinski, an entomologist with the University of Florida’s Institute of Food and Agricultural Sciences. “Windbreaks are one of the best things that you can do in terms of protecting the grove,” Pelz-Stelinski says. She says …
Approximately 200 Florida citrus industry members attended the HLB Grower Day on April 21 at the Citrus Research and Education Center (CREC) in Lake Alfred. Speakers summarized scientific presentations made at a recent international HLB research conference. Michael Rogers, an entomologist and director of the University of Florida/Institute of Food and Agricultural Sciences CREC, discussed control of the Asian citrus …
Tom Jerkins, president of the Citrus Research and Development Foundation, several years ago led a crowd at Florida Citrus Mutual’s annual meeting in chanting, “We need bactericides now!” The bactericides, which growers hope will significantly reduce HLB impacts on citrus trees, have been available to citrus growers for more than a year now. Most growers reportedly are using them, at …
University of Florida entomologist Kirsten Pelz-Stelinski presented an abundance of facts about Asian citrus psyllids at the recent Florida Citrus Growers’ Institute in Avon Park. Her presentation included a discussion on how far the HLB-spreading psyllids can travel and where they are predominantly found in citrus trees. “They’re quite capable of long-distance movement, about four miles we determined,” Pelz-Stelinski says. …
Several Florida growers recently have said that groves in the Gulf citrus region of Southwest Florida are looking better than most groves in the state. Additionally, statistics indicate production in the Gulf region exceeds production in the state as a whole. Multi-county citrus Extension agent Mongi Zekri, who represents the Southwest/Gulf region, was recently asked why the Gulf was doing …

University of Florida (UF) researcher Kelly Morgan discusses a study of how citrus growers are adjusting irrigation water pH levels, and what pH levels seem to work best. The acid level of citrus irrigation water has become an important consideration since HLB was discovered in Florida groves in 2005. “Jim Graham (a fellow UF researcher) has been conducting a survey …
Stephanie Slinski, Citrus Research and Development Foundation bactericide project manager, discussed grower trials on the use of bactericides for HLB at the Florida Citrus Growers’ Institute in Avon Park on April 4. She summarizes the presentation. “We have a series of field trials set up throughout Florida to test the efficacy of oxytetracycline and streptomycin just in the grower program,” …
By Jawwad A. Qureshi and Philip A. Stansly More than a decade has passed since 2006, when huanglongbing (HLB) or citrus greening disease was identified in Florida. By then, the disease had already spread widely and went unrecognized due to high psyllid populations and a disease incubation period of months or years between infection and symptom expression. Nevertheless, management of …
Steve Smith became executive director of the Peace River Valley Citrus Growers Association (PRVCGA) in early March. He discusses some of the issues the association will address. “Obviously the research is a major focus right now with greening. That’s at the top of everybody’s list, trying to find some solutions.” Water issues historically have been a major focus for the …
Harold Browning, chief operations officer at the Citrus Research and Development Foundation (CRDF), provides an overview of activities at the recent International Research Conference on HLB held in Orlando.

By Ernie Neff Gulf citrus growers had a CHMA (citrus health management area) before CHMAs were popular — even before they were called CHMAs! Phil Stansly, University of Florida (UF) entomology professor, is among those credited with organizing Florida’s first psyllid- and HLB-fighting CHMA. Others recognized for the achievement include Gulf Citrus Growers Association (GCGA), Florida Cooperative Extension Service and …
