Representatives of Fundecitrus and the Brazilian citrus industry went to Seville, Spain, to participate in a meeting about mechanical harvesting of citrus. The key objective was learning about different tools and machines designed for the mechanization of citrus handling. One example of machinery is the mechanized harvesting equipment used for densely cultivated orange groves. In one of their visits, the …
By Tina Buice The Citrus Research and Field Trial (CRAFT) program was created in 2019. Its work was centered on the mission of moving lab and research solutions into groves for commercial-scale field trials, collecting data on those trials and creating an integrated data management solution to present the results. Four years later, with more than 10,000 acres of new …

By Tripti Vashisth, Wesley Webb and Taylor Livingston As trees become symptomatic for HLB, leaves experience an imbalance of plant hormones. This hormonal imbalance exacerbates HLB symptoms and can lead to more stem dieback, poor vegetative growth and fruit drop. This ultimately leads to reduced bearing wood, resulting in yield losses and tree decline. Thus, the use of growth-promoting hormones …
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.

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.
