University of Florida Institute of Food and Agricultural Sciences researcher Lukasz Stelinski talks about the insecticide resistance that HLB-spreading psyllids develop and how to manage it. “There is insecticide resistance in Florida for Asian citrus psyllids,” Stelinski says. “It’s a phenomenon that occurs statewide, but in isolated areas.” “We actually have the tools and the knowledge to practice insecticide resistance …
By Arnold Schumann, Laura Waldo, William Holmes, Gary Test and Tim Ebert Artificial intelligence (AI) is increasingly common in electronic devices at home or work, in social media, video streaming services, electronic commerce, and in internet search engines. Now, AI is rapidly entering the farming scene. Growers using modern precision agriculture tools and techniques often face a barrage of high …
By Xavier Martini and Peter Andersen Cold-hardy citrus has a long history in North Florida, Alabama, Louisiana and Georgia. Records show that sweet orange, citron, lemon, lime and pummelo were brought to Saint Augustine, Florida, from Spain in 1565. However, it was not until the late 1700s that the Jesuits introduced satsuma (Citrus unshiu) to what is now Louisiana. SATSUMA …
By Brian German The Spring Citrus Meeting held last week in Tulare County touched on several major issues growers are concerned with, and included presentations on best practices for managing citrus trees. The day began with important information related to Asian citrus psyllid (ACP) and the disease it causes, huanglongbing (HLB), which has been growing at an alarming rate in …
The biopesticide company, Certis USA, presented the non-profit Citrus Research and Development Foundation, Inc. (CRDF) with a check for $20,000 to help fund research projects in an effort to find a cure for huanglongbing (HLB; citrus greening). The presentation was made during the Florida Citrus Industry Annual Conference that took place at the Hyatt Regency Coconut Point Resort and Spa. …

University of Florida Institute of Food and Agricultural Sciences researcher Christopher Vincent says kaolin clay outperforms foliar insecticides for management of HLB-spreading psyllids at times when kaolin’s use is practical. His presentation on the topic followed the Citrus Research and Development Foundation (CRDF) meeting on May 22 at the Citrus Research and Education Center in Lake Alfred. The presentation, part …
The total economic impact of California’s citrus industry is $7.117 billion according to a new study commissioned by the Citrus Research Board (CRB). “In updating our economic analysis, we selected a well-known expert, Bruce Babcock, Ph.D., a professor in the School of Public Policy at the University of California, Riverside, to conduct the research. His findings quantified the significant impact …
Researchers at the University of California, Riverside (UCR) claim they have made an important step in understanding the molecular mechanism of huanglongbing (HLB). They believe they have found the mechanism by which the disease evades detection and destruction by the natural immune system of citrus trees. HLB, or citrus greening disease, has devastated groves in Asia, South America and the …
By Lukasz L. Stelinski, Jawwad A. Qureshi and Philip A. Stansly Florida citrus is host to four main groups of mites categorized by differences in lineage and morphology. However, only rust mites, spider mites and broad mites historically cause economic damage to commercially grown citrus in the state. The fourth group, referred to as false spider mites, are vectors elsewhere …
Phil Stansly, University of Florida Institute of Food and Agricultural Sciences entomologist, discusses alternatives to imidacloprid for helping to control HLB-spreading Asian citrus psyllids (ACP). “Imidacloprid of course is typical of the neonicotinoids that we’ve been using as soil applications to protect young trees,” Stansly says. “We’ve seen and the growers have seen, too, that soil applications of systemic insecticides …
Water is a key ingredient in achieving a healthy citrus crop, but too little or too much can be detrimental. Two articles in the April issue of Citrus Industry magazine address irrigation management. In the first article, growers will learn about irrigation scheduling methods and get production pointers for trees impacted by HLB and Hurricane Irma. The second article looks …
By Tacy Callies Citrus growers and researchers alike are learning more about the role intensive nutrition management plays in keeping HLB-infected trees productive. The March issue of Citrus Industry magazine provides two features on nutrition management. The first is a foliar nutrition research update from a team of University of Florida scientists. The article offers a summary of results on …
By Jawwad A. Qureshi, Philip A. Stansly and Lukasz L. Stelinski Pest management has always been important for citrus production in Florida. It has become even more critical following invasion of the Asian citrus psyllid (ACP) and citrus leafminer (CLM), due to their association with huanglongbing (HLB or citrus greening) and canker diseases, respectively. ACP and CLM develop and reproduce …
By next year, a fence utilizing light sources is expected to be available to help protect some citrus structures and maybe even grove perimeters from the HLB-spreading psyllid. U.S. Department of Agriculture research entomologist Joe Patt explains the technology. “Photonic fence is a multi-modal system that uses several different types of light in order to detect, track, identify and, if …
The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) announced awards to combat citrus greening disease. The funding to support research and Extension programs is made through the emergency Citrus Disease Research and Extension Program (CDRE). CDRE was authorized as part of the 2014 Farm Bill. “The need to advance research and Extension to develop management …
Two University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professionals spoke at the recent Cold-Tolerant Citrus Production for the Southeastern Coastal Plain event about the current state of the industry. UF/IFAS entomologist Xavier Martini said he has seen growth in interest for cold-tolerant citrus between 2016 and 2017. He also said he has seen an increase in the …
By Len Wilcox The grower-funded California Citrus Research Board (CRB) is celebrating its 50th anniversary this year. Headquartered in the Central Valley city of Visalia, under the direction of president/CEO Gary Schulz, the CRB awards more than $7 million each year to researchers throughout California. Since 2008, CRB has focused much of its efforts on huanglongbing (HLB), with approximately $33 …
Economist Tom Spreen thinks advanced production systems (APS) and citrus under protective screen (CUPS) offer hope for some growers in the face of HLB. Spreen, a University of Florida Institute of Food and Agricultural Sciences professor emeritus, discussed APS and CUPS at a recent Gulf Citrus Growers Association economic seminar in LaBelle. Spreen says growing with APS “means you have …
