A Candidatus Liberibacter asiaticus (CLas)-positive Asian citrus psyllid (ACP) sample has been collected from a residential property in California’s Ventura County. CLas is the bacterium that causes HLB. The Citrus Research Board’s Jerry Dimitman Laboratory confirmed the positive sample. This is the first confirmed CLas-positive ACP sample found in Ventura County. The positive sample, comprised of 12 adult psyllids from …
Low temperatures and fluctuations in environmental conditions are among what researcher Ashraf El-Kereamy described as a “possible hypothesis” for the cause of lemon pitting in California’s San Joaquin Valley. Other possible causes include what he called “overdoing a good thing” such as fertilizer and irrigation, or something affecting the integrity of the lemon’s wax layers. El-Kereamy is director of the …
By Frank Giles and Tacy Callies The Citrus & Specialty Crop Expo hosted two citrus educational sessions during the Aug. 16–17 event held at the Florida State Fairgrounds in Tampa. The sessions included both long-term research aimed at delivering trees resistant to HLB as well as what growers can do today to help mitigate the effects of the disease in …
The first update of the 2023–24 orange crop forecast for the São Paulo and West-Southwest Minas Gerais citrus belt confirmed the initial May forecast of 309.34 million boxes. Fundecitrus announced the update on Sept. 11. The forecast for Hamlin, Westin and Rubi varieties was increased 3.5% to 58.09 million boxes. Other early-season varieties climbed 1.6% to 18.51 million boxes. The …
By Christopher Vincent, Tripti Vashisth and Gillian Zeng Michalczyk Hurricane Ian harmed citrus trees in much of Florida, especially in areas where sweet oranges are grown. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are tracking the health of trees in groves around the state as they struggle to recover. Fall applications of gibberellic acid before the storm …
Florida’s populations of Diaprepes abbreviatus root weevil have been uncharacteristically low so far in 2023, entomologist Lauren Diepenbrock reported recently. The adult pests are normally active in April–May and in the fall, the University of Florida Institute of Food and Agricultural Sciences assistant professor noted. Prior to the discovery of HLB disease in Florida in 2005, growers who had extensive …
Texas growers appear to be back on track after Winter Storm Uri caused significant setbacks to many groves in February 2021, according to a Texas A&M AgriLife Extension Service expert. ACREAGE STATUSDespite citrus production losses to the storm, Juan Anciso, AgriLife Extension horticulturist at Weslaco, said he was pleasantly surprised that the industry was faring much better than he expected. …
Brazil’s Fundecitrus is alerting citrus growers to take extra measures against leprosis during the current critical period for disease occurrence, May to September. At this time, fruit are in development, and the lack of rain favors outbreaks of the leprosis-transmitting mite. Leprosis is an important disease of Brazilian citrus that in recent years has caused significant damage to orange groves. …
Lukasz Stelinski, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomology professor, has been elected a fellow of the Entomological Society of America (ESA) for 2023. He is one of six recognized for outstanding contributions to entomology via research, teaching, Extension, administration, military service or public engagement and science policy. Stelinski works at the UF/IFAS Citrus Research …
By Lauren Diepenbrock A recently established snail species, Bulimulus bonariensis (also known as Bulimulus sporadicus), has been growing in population throughout the Southeast for the past few years. Growers first reported concerns about this snail in 2020 when they found the pest covering microjets and interfering with irrigation in the late spring/early summer (Figure 1). At the time, it was …
By Larry Duncan The growers advising the Citrus Research and Development Foundation understand very well the importance of cooperative research projects between growers and scientists. Several years ago, they earmarked a portion of research funding, not for carefully managed laboratory experiments or small plot trials at state, federal or private research centers, but rather for grower-run trials testing potential HLB …
The Citrus Research and Field Trial (CRAFT) Foundation has reopened the application window for its Existing Tree Therapies Program. Applications will be accepted until 5 p.m. on Aug. 31. Participants will be selected through a random lottery, administered by a third-party entity. The program is designed to provide the industry with a better understanding of the best use patterns, combinations …
By Brenda Eubanks Burnette Gap Kovach, formerly head of HESCO, recently sent me a surprise packet of goodies for the Citrus Archives that included citrus labels, the 1986 Miss Florida Citrus program and the Winter Park Public Library 1985 calendar.

The Florida Citrus Commission (FCC) on June 14 received an update about a program for expedited propagation, in which 23 nurseries are participating. The goal of the expedited tree propagation program is to have several million HLB-tolerant or HLB-resistant trees planted in the next several years. Rosa Walsh, Florida Department of Citrus (FDOC) director of scientific research, provided the update. …
By Sarah Strauss, Emma Dawson and Elena Karlsen-Ayala The term “soil health” has become increasingly popular in the last several years. While there are many definitions of soil health, one of the more commonly cited ones is from the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS). It defines soil health as “…the continued capacity of a soil …
Highlands County Citrus Growers Association (HCCGA) President Aaron Nelson recently shared observations about trunk injection of oxytetracycline (OTC) for trees with HLB. The first formulations for citrus trunk injection became available in January. His observations follow: Over the course of the last six months there have been countless hours spent injecting millions of trees all over the state. What follows …
Psyllids collected in orchards in four microregions of Brazil’s citrus belt showed reduced susceptibility to insecticides from the pyrethroid and neonicotinoid chemical groups. That information was reported earlier this year by agronomist and researcher Fernando Amaral of the Arthropod Resistance Laboratory at the Luiz de Queiroz College of Agriculture/University of São Paulo (ESALQ/USP). This was the first confirmation of psyllid …
Hurricanes Ian and Nicole in 2022 caused early fruit drop in the Indian River area, where two studies of 39,000 trees that might tolerate HLB are being conducted. Researchers now expect significant data from the studies will come after the 2023, 2024 and 2025 season harvests, but they have already gained some insights from the projects. The first experimental grove, …
For at least the last four years, the Valencia SPB-1-14-19 orange has been the most-produced citrus variety in Florida, and US-942 has been the favored rootstock. So, it makes sense that the Valencia SPB-1-14-19 on US-942 rootstock has been the most-produced tree combination for four years running. That information was provided at April’s Florida Citrus Growers’ Institute in Avon Park …
