By Fernando Alferez, Susmita Gaire, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri Controlling the Asian citrus psyllid vector of huanglongbing (HLB) is critical, especially in young trees. Reducing HLB incidence is essential for tree survival and productivity under current endemic conditions. Individual protective covers (IPCs) are a novel strategy based on psyllid exclusion by means of a protective …
At Citrus Expo, economist Ariel Singerman discussed the economics of producing citrus under protective screen (CUPS) and covering young trees with individual protective covers (IPCs). The primary purpose of both strategies is to exclude HLB-spreading Asian citrus psyllids. Singerman is with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Singerman calculated that a CUPS grower who insures …
Long-time multi-county citrus Extension agent Mongi Zekri, who serves Southwest Florida counties, says individual protective covers (IPCs) work well in the fight against citrus greening, also known as HLB. “They have been very effective in controlling or managing citrus greening, because they don’t allow the citrus psyllid, which is the vector of the disease, to get to the tree,” Zekri …
By Lauren Diepenbrock and Nicole Quinn In recent years, a new pest has been added to the ever-evolving scope of pest management in Florida citrus: Bulimulus bonariensis snails. These snails, also referred to as ghost snails or peanut snails, were reported to be clogging irrigation jets in Central Florida in 2020 in limited locations. Now, in 2025, they have spread …
Researchers from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture (USDA) delivered several presentations to a standing-room-only audience during the citrus seminars at the Florida Citrus Show in March. VARIETIES AND ROOTSTOCKS The citrus session began with a breeder panel discussing research on varieties and rootstocks. Participants were Manjul Dutt and Jude …
By Maegan Beatty During a recent citrus insect management workshop at the Citrus Research and Education Center, Larry Duncan, University of Florida Institute of Food and Agricultural Sciences professor, addressed diaprepes root weevil management. This Caribbean pest was introduced to Florida in the 1960s. The adult pests feed and lay eggs in citrus tree canopies. The larvae feed on roots …
By Fernando Alferez, Divya Aryal and Saoussen Ben Abdallah In the last few years, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus horticulture team at the Southwest Florida Research and Education Center (SWFREC) in Immokalee has performed several research trials in commercial farms and at the experimental farm at the SWFREC to elucidate the effect of …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center in Immokalee hosted a citrus field day on April 10. The event showcased the research being conducted at the center. One of the tour stops featured individual protective cover (IPC) research led by Fernando Alferez, UF/IFAS associate professor of citrus horticulture. Thanks in …
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 …
Florida citrus land fell from 748,555 acres in 2004 — the year before HLB was found in the state — to 274,705 acres in 2024, according to a recent summary of the 2023–24 citrus season. The summary, Florida Citrus Statistics 2023–2024, was published by the Florida Department of Agriculture and Consumer Services (FDACS) Division of Fruits and Vegetables. The statistics …
A recent study sheds light on the significant effects of Candidatus Liberibacter asiaticus (CLas), the bacterium responsible for HLB, on the root systems of grafted Valencia orange trees. The findings reveal that root system reductions caused by the infection are more extensive than the corresponding aboveground declines. That finding underscores the hidden yet critical impact of the disease below the …
Hurricanes bring immediate tree damage from high winds and torrential rainfall, but storms also can lay the groundwork for citrus disease problems. Soon after Hurricane Milton passed through citrus-growing regions, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a webinar that covered various topics including post-storm disease management. CANKER Megan Dewdney, UF/IFAS associate professor of plant …
By Romain Exilien and Xavier Martini Residential gardens serve as reservoirs for Asian citrus psyllids (ACP) and citrus greening disease (also known as huanglongbing or HLB) due to unmanaged citrus trees. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) conducted a survey to assess residents’ needs regarding ACP and HLB management. The survey examined their current control …
Biological control can have a significant impact on Asian citrus psyllid (ACP) and citrus leafminer (CLM) populations in Florida, a researcher reported in a Nov. 19 virtual meeting. Jawwad Qureshi, associate professor of entomology with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), also discussed some cultural and chemical controls that work on the pests. ACP Qureshi, …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Lauren Diepenbrock recently offered post-hurricane observations and management suggestions for some insects and snails. Diepenbrock is an assistant professor at the Citrus Research and Education Center. BULIMULUS SNAILS Related Bulimulus snail species have been found to lay eggs in the fall after major rain events. Both small and larger …
Citrus canker could spread in Florida groves as a result of Hurricane Milton, researcher Megan Dewdney warned. A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of plant pathology, Dewdney offered suggestions for dealing with canker at a recent UF/IFAS hurricane recovery webinar. WIND WOUNDS High winds and rain, which were abundant during the hurricane, move …
Phytophthora, citrus black spot and HLB are among diseases that could be spread in Florida groves as a direct or indirect result of Hurricane Milton, researcher Megan Dewdney cautioned. Dewdney, a University of Florida Institute of Food and Agricultural Sciences associate professor of plant pathology, offered suggestions for dealing with those diseases during a recent hurricane recovery webinar. PHYTOPHTHORA Phytophthora …
A few themes are unfolding as Florida’s citrus industry begins to assess Hurricane Milton’s damage. First, it could have been worse. The overall citrus losses do not appear to be as bad as those incurred from Hurricane Ian in 2022. Second, the hurricane affected nearly the entire Florida Citrus Belt, but damage varies greatly depending on the specific area. Reports …
Associate Professor Fernando Alferez and his team at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) learned several years ago that individual protective covers (IPCs) protect newly planted trees from HLB. They do that by excluding the Asian citrus psyllids (ACP) that spread the devastating citrus disease. But multi-county citrus Extension agent Mongi Zekri noted that IPCs …
By Lukasz Stelinski, Eric Roldan and Kirsten Pelz-Stelinski Use of antibiotics in fruit production is not a new idea, but it has only recently been applied on a larger scale in Florida citrus. The initial labels for huanglongbing (HLB) treatment with antibiotics in Florida citrus were approved in March 2016 in response to significant economic losses caused by HLB. Antibiotics …
