Federal and state agriculture officials recently made changes to huanglongbing (HLB, also known as citrus greening disease) and Mediterranean fruit fly (Medfly) quarantines in California. They also removed a Mexican fruit fly (Mexfly) quarantine in Texas. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) reported these changes. CALIFORNIA HLB On Nov. 25, APHIS and the California …
Brazil’s Fundecitrus recently published a scientific article explaining why HLB is so difficult to control. “Why is it so difficult to control huanglongbing (HLB)? Point of view” was published by the journal Scientia Agricola (Agricultural Science). It was authored by Fundecitrus researcher Renato Bassanezi and post-doctoral researcher Isabela Vescove Primiano, in collaboration with the late professor Armando Bergamin Filho of …
By Michael Rogers It has now been two decades since huanglongbing (HLB), or citrus greening, was first detected in Florida. That announcement in August 2005 changed everything for the Florida citrus industry. At the time, Florida citrus was still a global powerhouse. Less than a year earlier, HLB had been confirmed in Brazil, and we were aware of its devastating …
Federal agriculture officials on Nov. 25 announced the expansions of the areas quarantined for sweet orange scab (SOS) and huanglongbing (HLB) diseases in California. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the California Department of Food and Agriculture (CDFA) enacted the expansions. SOS The SOS quarantined area has been expanded by 5 …
Fundecitrus recently held an international seminar dedicated to citrus greening. The event had approximately 150 participants and featured experts from China and Brazil. GENOME EDITING Xuefeng Wang, from China’s Southwest University’s Citrus Research Institute, highlighted his interest in building a solid partnership in the area of genome editing. He said his group has already identified promising genes that can contribute …
The Citrus Research and Development Foundation (CRDF) convened its November board of directors meeting to take up recommendations from its Research Management Committee. According to Rick Dantzler, CRDF chief operating officer, one of those recommendations was funding a proposal from Swadesh Santra, who is a professor of chemistry with the University of Central Florida. “This funding would allow Dr. Santra …
The first half of November saw the most sprouting ever observed in Brazilian citrus by the Psyllid Alert, reaching 37.4%. This scenario raises an alarm for citrus growers, since the increase in sprouting is directly linked to the growth of the psyllid population, the insect vector of huanglongbing (HLB) disease. HLB is also known as citrus greening. According to the …
California’s huanglongbing (HLB, also known as citrus greening) quarantine and its Santa Clara Mediterranean fruit fly (Medfly) quarantine were recently expanded. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the California Department of Food and Agriculture (CDFA) expanded the quarantines. HLB The HLB-quarantined area in Riverside County was expanded by 3 square miles. …
By Peter Chaires Last month’s Citrus Nursery Source article promised additional details on New Varieties Development & Management Corp.’s (NVDMC) 2025–26 sponsored projects. While there is only space for general summaries, it is important to highlight the areas of focus for each research team, and the emphasis on short-term benefits while continuing to build a foundation for the future. NVDMC …
Golden Ridge Groves will open Nov. 20 in Alturas, Florida. The new business includes u-pick in a citrus under protective screen (CUPS) structure and a farm market. The operation will be open for the season Tuesday through Saturday, 10 a.m. to 6 p.m. Husband and wife owners Shane and Katie Bevilacqua answered questions about the new business. Q: When will …
Brazilian citrus research organization Fundecitrus (Fund for Protection of Citriculture) recently honored University of California Davis (UC Davis) Distinguished Professor Walter Leal for his outstanding contribution to citriculture. Fundecitrus emphasized the importance of Leal’s work on the Asian citrus psyllid (ACP) and citrus fruit borer. Brazilian native Leal is a member of the Department of Molecular and Cellular Biology faculty …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are putting genes from a non-citrus plant into Hamlin oranges to develop citrus plants that fight huanglongbing (HLB), also known as citrus greening disease. The newly developed plant is called NuCitrus. It’s based on a protein called Arabidopsis NPR1 (AtNPR1). The new citrus shows strong tolerance to HLB, but not …
The October All In For Citrus podcast features citrus under protective screen (CUPS). Over the past decade, the practice has grown in popularity due to its ability to exclude the Asian citrus psyllid and huanglongbing (HLB) disease. Roughly 1,500 acres of citrus are grown under screen in Florida with more acreage under development. Lauren Diepenbrock, associate professor of entomology at …
As every Florida citrus grower knows, it has been difficult to grow trees and fruit profitably since huanglongbing (HLB) disease was discovered in the state in 2005. Soon after the disease was discovered, officials determined it couldn’t be eradicated largely because the Asian citrus psyllids (ACP) that spread it showed up years earlier and were in virtually all citrus-producing regions. …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher recently highlighted a number of benefits from using silicon as a nutrient for citrus. Muhammad Shahid, assistant professor at the North Florida Research and Education Center, presented silicon research findings at the Citrus & Specialty Crop Expo in August. According to Shahid, silicon is categorized as a plant …
By Lauren Diepenbrock Unlike northern regions, fall in Florida is not generally a time when insect, mite and other invertebrate pest populations decline rapidly. In Florida citrus, we generally see the opposite of this trend. In the hot, dry end of summer and early fall, mite populations often soar, requiring management to prevent excessive damage to fruit. (See The Florida …
At the recent Citrus & Specialty Crop Expo, Ozgur Batuman reminded seminar attendees there is no silver bullet for HLB management. Instead, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher proposes that growers integrate several tools for the management of HLB. These tools include a variety of ways to control HLB-spreading psyllids; oxytetracycline (OTC) trunk injection; …
The University of Georgia (UGA) has disease labs and clinics to help citrus producers determine what diseases are impacting their trees. Jonathan Oliver, UGA assistant professor and small fruits pathologist, highlights the diagnostic facilities that growers can take advantage of. “We have a lab in Tifton, the Plant Disease Clinic, that can accept samples from commercial citrus,” Oliver said. “We …
