Scientists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and the U.S. Department of Agriculture Agricultural Research Service (USDA/ARS) recently wrote about efforts to identify HLB-affected versus healthy citrus fruit. UF/IFAS scientists are Mark Ritenour, Ketan Shende and Thomas Burks. Michelle Heck is with the USDA/ARS. A slightly edited version of their article follows: Most citrus …
It is much better for Florida citrus growers to be proactive than reactive when managing pest populations. Scouting and monitoring citrus groves is crucial for growers who hope to thwart off impacts from insects like the Asian citrus psyllid (ACP). If growers are not successful, they will be behind the eight ball in minimizing the impact of these annual pests. …
It can be hard to have hope if you are a farmer in today’s agricultural climate. It can be even harder to have optimism if you are a Florida citrus grower. Yet, Matt Joyner, Florida Citrus Mutual executive vice president and chief executive officer, has hope that the industry is trending upward even amid HLB and multiple hurricanes in previous …
Federal and state officials have expanded the quarantine for huanglongbing (HLB, also known as citrus greening disease) in the Mission Viejo area of California’s Orange County. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture, expanded the quarantine by 13.16 square miles. The expansion was in response …
By Fernando Alferez and Saoussen Ben Abdallah Individual protective covers (IPCs) are now being increasingly adopted in Florida to protect newly planted citrus trees from psyllid colonization. The risk of new citrus plantings becoming infected with HLB is especially high, as young trees flush more frequently and attract more psyllids. However, the adoption of IPCs does not occur in all …
By Brenda Eubanks Burnette I was honored this year to be part of the Vero Heritage Center and Indian River Citrus Museum’s “Deeply Rooted” event, which was the kick-off for Indian River County’s Centennial Celebration. It made me think of this year’s Florida Citrus Hall of Fame inductees. They all have something in common with deep roots — Polk County! …
U.S. Rep. Kat Cammack from Florida and colleagues recently reintroduced the bipartisan Fair Access to Agriculture Disaster Programs Act. The act is aimed at removing barriers to agriculture disaster assistance for producers. The bill would provide farmers, ranchers and other agriculture producers with improved access to federal disaster assistance following natural disasters. Reps. Jimmy Panetta and Zoe Lofgren, both of California, …
By Maegan Beatty During the recent citrus insect management workshop at the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center, Larry Duncan, a nematology professor, discussed the sting nematode. First recognized in the 1980s as a pest of young citrus trees, the sting nematode has adapted to coarse, sandy soils. The pest feeds at …
Rick Dantzler, Citrus Research and Development Foundation (CRDF) chief operating officer, believes there is a future for Florida’s citrus industry. His optimistic outlook is based on approaches that researchers have implemented to help growers survive in the short term, such as oxytetracycline (OTC) trunk injection, and work toward the development of an HLB-resistant tree. Dantzler shared that hope during the …
A U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) report forecasts Chinese mandarin and grapefruit production will both increase slightly in 2024–25. TANGERINES/MANDARINS China’s production of tangerines and mandarins is forecast at 27 million metric tons (MMT), up from 26.9 MMT the prior year. Increasing production in multiple cities is expected to outpace the negative effects of citrus greening …
By Maegan Beatty Last month, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a citrus insect workshop that covered almost 10 different pests that pose a threat for Florida citrus. Lance Osborne, professor and researcher at the Mid-Florida Research and Education Center, presented research on chilli thrips. Chilli thrips (Scirtothrips dorsalis) can live in over 150 …
It is best for citrus growers to implement a proactive approach to weed management. Being reactive puts producers behind the eight ball with regards to controlling certain weeds in their groves. That’s why Ramdas Kanissery, weed scientist and associate professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), is preaching the importance of pre-emergent herbicides. They …
“For the incidence to be zero, the control needs to be 10.” That’s the motto of the new Fundecitrus campaign to mitigate the incidence of citrus greening in Brazil. The campaign highlights the need for strict control of the greening-spreading psyllid, especially in new regions where citrus farming is advancing. Those regions include the states of Mato Grosso do Sul, …
Now is the time for Florida citrus growers to implement management tactics to control the Asian citrus psyllid (ACP), the insect that vectors citrus greening, also known as huanglongbing (HLB). ACPs are currently in low populations across Florida’s citrus-producing region. That means growers should act now to protect their crop from the insect’s impact, says Chris Oswalt, University of Florida …
Eating an orange a day may lower a person’s depression risk by 20%, according to a study led by Raaj Mehta, an instructor in medicine at Harvard Medical School. Mehta is also a physician at Massachusetts General Hospital. Mehta said a postdoctoral student he was working with found a 2016 paper pointing to the possibility that citrus lowers the risk …
Citrus greening disease, also known as huanglongbing (HLB), is not yet widespread in Georgia. However, there’s no reason to think that it won’t become more of a problem for the state’s citrus growers. Lindy Savelle, executive director of the Georgia Citrus Association (GCA), hopes it doesn’t happen but cautions growers about the disease’s potential beyond Florida. “Something we have to …
A tool predicting how to protect European citrus from HLB shows how mathematical modeling can help prepare for future plant disease invasions. Europe is currently unaffected by HLB. However, there are increased concerns of an infestation since psyllids that spread HLB have been found in key citrus-producing countries, including Portugal and Spain. In response to the HLB threat, a new …
The California Department of Food and Agriculture (CDFA) recently announced the expansion in Orange County of an emergency program for HLB and the Asian citrus psyllid (ACP) that spreads the disease. The expansion follows confirmation throughout January of the causative bacterial agent of HLB in plant tissue and/or ACP in Anaheim, Costa Mesa, Garden Grove, Irvine, Mission Viejo, Orange, Santa …
SHOW ADDRESS The Florida Citrus Show will be held in the parking lot between the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (2199 South Rock Road) and the U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) U.S. Horticultural Research Laboratory (USDA-ARS, 2001 South Rock Road) in Fort Pierce.

By Megan Dewdney Despite being in a transition from a La Niña to a neutral El Niño Southern Oscillation phase, Florida has not had warmer than average temperatures in the last two weeks from March 3. Looking at historical trends, temperatures for the last two weeks of February were in the normal range for this time of year. When looking …
