HLB-Spreading Psyllids Resistant to Insecticides
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 …
Rootstocks and HLB Tolerance — Another Perspective
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, …
High-Density Planting Increases Yields
Larry Black, general manager of Peace River Packing Company in Fort Meade, told growers at the recent Florida Citrus Mutual conference about his company’s success with high-density plantings.

Growers desiring to qualify oranges for export to South Korea must comply with the FRB protocol during the 2017-2018 shipping season. Growers are required to implement the following measures for FRB control on oranges: 1. Skirt-prune trees to prevent …
Field Trials of Rootstocks and Scions: What Can They Tell Us?
By Harold Browning Column sponsored by the Citrus Research and Development Foundation Plant breeding programs have been a mainstay of citrus production worldwide. They have served as a basis for gradual improvement in fruit quality, adaptability to varying growing environments, and most importantly, to disease management. For that reason, new germplasm has been a front line of pursuit in the …
Hunt on FDOC Budget and Grove Conditions
The Florida Citrus Commission (FCC) on June 21 set a preliminary 2017-18 Florida Department of Citrus (FDOC) operating budget of $17.5 million. That’s a 22 percent reduction from last season and the lowest FDOC budget in decades.

Grower Has Tepid Report on Bactericides for HLB
Three years ago at the annual Florida Citrus Mutual Conference in Bonita Springs, Tom Jerkins, who was and still is president of the Citrus Research and Development Foundation, enthusiastically led the crowd in chanting, “We need bactericides now!” At the same conference this year (June 15), Jerkins gave a less than enthusiastic report on his company’s yield results following one …
Pros and Cons of H-2A for Growers and Workers
The federal H-2A program that allows temporary agricultural guest workers from other countries has grown dramatically in recent years. Approximately 80 percent of all Florida citrus is harvested by H-2A workers, says Carlene Thissen, coordinator for farm labor supervisor training at the Southwest Florida Research and Education Center in Immokalee. She says the number of H-2A workers in Florida citrus …
What Have We Learned?
By Harold Browning Column sponsored by the Citrus Research and Development Foundation Within the Citrus Research and Development Foundation (CRDF), the daily challenge of keeping up with a wide array of HLB topics, more than 75 currently funded projects, and monthly committee and board meetings translates into a constant flow of information. Project managers meet weekly to discuss progress and …
Keeping Young Trees Free of HLB
Plant pathologist Megan Dewdney was one of the University of Florida Institute of Food and Agricultural Sciences researchers who summarized scientific presentations made at the 2017 International Research Conference on HLB. She and others spoke at an HLB Grower Day in Lake Alfred, putting the complex presentations into terms more understandable to those who aren’t scientists. Dewdney discussed young tree …
Grower Discusses Many HLB-Related Issues
Wauchula citrus grower and orange grove salesman Kenny Sanders was one of the growers sharing experiences at a recent grower roundtable meeting in Wauchula.

Best and Worst Ways to Control Psyllids
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 …
Growers Discuss Bactericides and Psyllid Control
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.

Psyllids: Windbreaks, Grove Orientation and Tree Planting
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 …
