Specialty crop growers might be aware of the disease sweeping through Florida’s citrus industry. Its impact has been tremendous and has tested the survival of the state’s signature crop. This year will mark the 20th anniversary of the official confirmation of citrus greening disease (also known as huanglongbing or HLB) in Florida. In the past two decades, the state’s output …
The Florida Citrus State of the Industry Survey seeks input from growers on key issues affecting their groves. While not a scientific survey, it has reflected general trends over the years. This year’s survey asked growers to weigh in on major events like the impact of Hurricane Milton and the performance of trunk-injection therapies. HURRICANE MILTON Hurricane Milton made landfall …
After hurricanes hit citrus-producing regions in Florida, there is always one question included in the conversation: How bad is it? Experience has shown that the damage from hurricanes can take months to fully manifest. And recovery can take years, especially in the HLB-era. Within a week after Hurricane Milton making landfall on Oct. 9, the University of Florida Institute of …
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 …
Texas A&M AgriLife Research scientists led by Kranthi Mandadi are seeking novel solutions to huanglongbing (HLB), also known as citrus greening disease. Mandadi is a professor in the Texas A&M Department of Plant Pathology and Microbiology and a researcher at the Texas A&M AgriLife Research and Extension Center at Weslaco.

By Brenda Eubanks Burnette University of Florida Professor P.H. Rolfs gave a speech during the 1935 Florida State Horticultural Society (FSHS) meeting about the “Founders and Foundations of Florida Agriculture.” (FSHS Proceedings, 1935). An interesting read, it touched on many of the major industry members of the time, but I truly loved the following excerpt I found under the heading …
Not all citrus disease concerns center around huanglongbing (HLB). While HLB disease garners much of the headlines because of its devastation to Florida’s citrus crop, growers in the cold-hardy citrus region should be mindful of other diseases that can devastate a crop if left untreated. Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, highlighted some of …
Several citrus growers, consultants and others from São Paulo, Brazil, recently toured Florida’s Indian River citrus region to examine the management of HLB. Flavia Zambon, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor of horticultural production at the Indian River Research and Education Center (IRREC), hosted the group. “In the traditional production region known as the …
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 …
Many Florida citrus growers view new trunk-injection therapies as a lifeline to help them stay viable in the ongoing battle against HLB. After two seasons of trunk-injection applications of oxytetracycline (OTC), growers are evaluating the impacts on tree health, production and quality. Heading into next season’s treatment cycle, now is the time to consider product options. Factoring into this decision …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) on Oct. 16 presented a hurricane recovery webinar less than a week after Hurricane Milton crossed the state. Among the topics addressed were damage assessment and fruit drop. DAMAGE ASSESSMENT Multi-county citrus Extension agent Chris Oswalt recommended that growers check trees for damage in multiple locations within groves, starting …
Sponsored Content In this special series, Tom Johnson, owner of TJ BioTech, tackles questions about optimizing trunk-injection applications to treat HLB. Q: After a series of weather challenges, including Hurricanes Helene and Milton, what are you hearing from Florida citrus growers about the continued health and recovery of groves going forward? Tom Johnson: I am certainly not suggesting that I …
The University of Florida Institute of Food And Agricultural Sciences (UF/IFAS) Economic Impact Analysis Program is deploying a survey to assess the agricultural impacts of Hurricane Milton. Once it is safe to do so and immediate needs are met, Florida’s agricultural producers are encouraged to complete the following steps related to assessing and reporting agricultural losses and damages: This UF/IFAS survey is …
By Ariel Singerman This article examines the impact of HLB and other factors on yield by tree age group in Florida using U.S. Department of Agriculture statewide average data from 1994 to 2021. To focus on the impact of HLB and other relevant lasting factors, seasons in which there were hurricanes or freezes are excluded. YIELD REDUCTIONS Figures 1 and …
Growers have numerous things to think about when planting a new grove.

By Tripti Vashisth Over the past decade, HLB-associated fruit drop has become a significant problem in Florida groves. Many growers opt to harvest the fruit before the peak fruit drop begins. However, the downside to this strategy is that the fruit does not get enough time for optimal Brix accumulation. Plant growth regulators, when applied at the right time, can …
HLB has reduced citrus production across the board, but early varieties like Hamlin have taken an even bigger hit. Hamlin has been plagued by the disease and fruit drop, which has left a void in the juice-processing segment in the early season. Growers who have been replanting have mostly relied on later-season varieties like Valencia because it seems to be …
