By Ute Albrecht and Leigh Archer Trunk injection is an alternative technique for applying crop protection materials. This technology has now been approved to deliver oxytetracycline (OTC) for huanglongbing (HLB) management in Florida. Injections cause injury, and best practices need to be established to minimize injection-induced tree damage. University of Florida Institute of Food and Agricultural Sciences researchers (UF/IFAS) injected …
By Matt Smith One of the things I like most about being an Extension agent is getting to work with new growers. Despite all odds, some of these growers are getting into citrus. With hurricane season underway, it’s good for new growers to know — and for established growers to refresh themselves on — how to prepare before a storm …
On Sept. 20, Georgia Agriculture Commissioner Tyler Harper announced, in coordination with the U.S. Department of Agriculture (USDA) and the University of Georgia (UGA), the discovery and destruction of a second yellow-legged hornet’s nest on Wilmington Island near Savannah. The yellow-legged hornet is a non-native species that, if allowed to establish in the United States, could threaten honey production, native …
The Citrus Research and Development Foundation (CRDF) approved three new projects during its September board of directors meeting. The projects will test the injection of different antimicrobial materials to treat HLB. One project will be managed by Ozgur Batuman, a citrus pathologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Another will be run by Kranthi …
A federal pest risk assessment for the importation of fresh citrus from Japan has identified the Japanese orange fly (Bactrocera tsuneonis) as posing a high risk of introduction into the United States. The 120-page assessment was prepared by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS). The agency assessed the risk of scores of insects, …
The Wedgworth Leadership Institute for Agriculture and Natural Resources (WLI) recently selected 30 participants for Class XII of its two-year leadership development program. The program’s first seminar will take place in Gainesville in November. Participants have committed to 11 seminars, totaling 55 days, which further develop their leadership capacity in representing agricultural and natural resources industries. Seminars will be held …
The California Department of Food and Agriculture (CDFA) has declared a quarantine in Ventura County following the detection of the citrus disease huanglongbing (HLB), or citrus greening, in two citrus trees on one residential property in the city of Santa Paula. These detections are the first HLB-positive trees in Ventura County. CDFA is working with the U.S. Department of Agriculture …
The 2023–24 California forecast for Tango and W. Murcott Afourer mandarins is 21 million 40-pound cartons, the California Department of Food and Agriculture (CDFA) recently reported. This forecast is based on the results of the 2023–24 mandarin objective measurement survey, which was conducted from July 1 to Sept. 1, 2023. This is the first time the U.S. Department of Agriculture’s …
By Fernando Alferez, Daniel Boakye, Murillo De Sousa and Pablo Orozco After HLB was first detected in Florida, increase in disease-associated preharvest fruit drop in affected trees has significantly reduced grower returns. Fruit drop is normal in healthy citrus, accounting for 10% to 15% of the total crop. However, under endemic HLB conditions and depending on the variety, crop loss …
Citrus breeder Jude Grosser recently shared tips on tree nutrition and discussed some scion/rootstock combinations that should work well for trees producing juice oranges. NUTRITIONGrosser became very interested in citrus nutrition several years ago in an effort to keep his newly bred trees healthy in the face of HLB. The University of Florida Institute of Food and Agricultural Sciences professor …
In the nearly two decades that huanglongbing (HLB) has plagued Florida citrus groves, about $1 billion has been spent in the search for solutions. A lot of great scientists in Florida and around the world have worked on the problem, and a silver bullet, if there is one to be found, has been elusive. Researchers, along with growers, have developed …
By Ozgur Batuman Plant virus diseases are unusually difficult to manage if introduced into new production sites. Citrus-infecting viruses, particularly those spread by insect vectors, are no exception to this. Florida is regularly challenged by a barrage of invasive pests and pathogen species that could devastate the citrus industry. Viruses causing citrus leprosis and citrus yellow vein clearing diseases are …
UPDATE: Both the Oct. 9 and Oct. 13 listening sessions have been postponed. Florida Commissioner of Agriculture Wilton Simpson will host a farm bill listening session with U.S. Rep. Kat Cammack in attendance on Oct. 13. The session will allow Florida’s growers and ranchers to voice recommendations for the 2023 U.S. farm bill and related agricultural issues. The farm bill …
Using the plant growth regulators (PGRs) gibberellic acid (GA), 2,4-D and cytokinin in combination can maximize the benefit for HLB-affected trees, researcher Tripti Vashisth reported recently. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of citrus horticulture and production works at the Citrus Research and Education Center in Lake Alfred. She discussed the benefits of …
The Florida Fruit & Vegetable Association (FFVA) recently requested the rejection of Miami-Dade County’s proposed Heat Standard for Outdoor Workers. FFVA urged the county’s Community Health Committee (CHC) to engage agricultural producers in developing a meaningful and workable standard. FFVA argued that the proposed standard is intentionally broad and punitive and does not provide the support needed for implementation. The …
The Citrus & Specialty Crop Expo ventured into new territory this year — literally. After three decades at the Lee Civic Center in Fort Myers, this year’s event was held at the Florida State Fairgrounds in Tampa. There were several factors forcing the move this year, including damage to the Lee Civic Center from Hurricane Ian. With a new facility …
The U.S. Department of Labor (DOL) on Sept. 12 proposed a new rule that would strengthen protections for temporary foreign farmworkers in the H-2A program. This is the third proposed regulation tied specifically to the H-2A program in the last year. It follows the final DOL rule published in October 2022 that modernized key aspects of the H-2A program and …
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 …
Portions of Contra Costa and Santa Clara counties in California have been placed under quarantine for the Oriental fruit fly (OFF), and a quarantine in Orange County has been removed. See the updated quarantine map here. CONTRA COSTA COUNTYIn Contra Costa County, detections near the cities of Brentwood and Oakley have resulted in a quarantine zone covering 99 square miles. …
By Ute Albrecht, Larissa Nunes and Gabriel Pugina The current label recommends trunk injection of oxytetracycline (OTC) into the rootstock, but this may not always be possible. Previous University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) studies have shown that both rootstock and scion injections are effective. However, researchers have not yet studied if different rootstocks influence …
