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 …
A few weeks after Yiannis Ampatzidis started working at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) in 2017, Hurricane Irma wreaked havoc on Florida citrus groves. Growers needed to count their trees with precision to get crop insurance, but it was a laborious, time-intensive task. Ampatzidis, associate professor of agricultural and biological engineering at the Southwest …
By Ute Albrecht, Carol Tardivo, Gabriel Pugina, Larissa Nunes, Jasmine de Freitas and Gerardo Moreno Since the approval of oxytetracycline (OTC) injection to manage citrus greening (huanglongbing, HLB) in Florida, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant physiology team at the Southwest Florida Research and Education Center (SWFREC) has completed various research trials with multiple …
Soil microbiologist Sarah Strauss on Jan. 28 discussed the benefits, challenges and unknowns of cover crops, compost and humic acid for citrus soil health. Strauss is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Southwest Florida Research and Education Center. She pointed out that Florida’s citrus soils are problematic because they are 98% …
By Lauren Fessler Mathews, Sanju Kunwar, Ana Redondo and Ozgur Batuman Based on numerous research studies conducted by scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), it has been proven that injections of oxytetracycline (OTC) can help to alleviate symptoms caused by huanglongbing (HLB) disease. This treatment is now widely practiced and crucial for preventing …
By Ute Albrecht, Gabriel Pugina and Caroline Tardivo Two years have passed since trunk injection of oxytetracycline (OTC) was approved for HLB management in Florida. Many growers have adopted this technology. While most reported positive responses, others did not. The plant physiology team at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education …
By Ramdas Kanissery Spot application of post-emergent herbicides provides an effective solution for controlling weeds that are missed by standard maintenance herbicide programs in citrus groves (Figure 1, left). This method is also helpful for targeting weeds in areas that herbicide boom sprayers can’t reach, like those growing near the trees (Figure 1, right). Here are some key tips to …
By Ozgur Batuman, Sanju Kunwar and Ana Redondo In a promising effort to protect citrus from huanglongbing (HLB), University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are exploring the potential of Australian lime as an interstock graft for Valencia scions with Swingle rootstock. The interstock technique uses various limes, known for their natural HLB-tolerant peptides, between the …
Individual protective covers (IPCs), used primarily to protect young citrus trees from HLB-spreading Asian citrus psyllids, have become ubiquitous in Florida citrus groves in recent years. New University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows the trees grown under the IPCs also grow well for a few years after growers remove the bags. Growers typically remove …
By Ramdas Kanissery Managing weeds during the summer is crucial for Florida citrus. However, due to the high temperatures typical of Florida’s summer months, several factors must be considered when using herbicides in citrus groves during hot weather. INCREASE EFFECTIVENESS High heat and drought stress can slow plant growth and affect how herbicides move or translocate in weeds. When temperatures …
By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) is the vector of huanglongbing (HLB) disease associated with the phloem-limited bacterium Candidatus Liberibacter asiaticus. Infected trees start to decline and produce poor-quality fruit, which drops prematurely. Consequently, citrus production has decreased dramatically since the advent of HLB in Florida in 2005. There is no cure for the disease yet. …
By Ramdas Kanissery Finding the right time to apply post-emergent herbicides for controlling weeds in citrus groves is challenging in the summer months due to frequent rain. Rainy conditions delay grove maintenance, including herbicide spraying, while also impacting the effectiveness of the herbicides. Monitoring weather forecasts and identifying optimal conditions for herbicide applications can help achieve the best results. Below …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) weed scientist Ramdas Kanissery offered numerous tips and observations for improving herbicide efficiency at this spring’s Florida Citrus Growers’ Institute. They included: In addition to discussing herbicides, Kanissery reported that cover cropping, an emergent practice in Florida citrus production, may contribute to longer-term weed management in row middles.

Phytophthora incidences are increasing in Florida citrus groves, plant pathologist Ozgur Batuman reported during a May 21 presentation. Phytophthora diseases include foot rot of trunk and limbs, root rot and brown rot. Batuman, a University of Florida Institute of Food and Agricultural Sciences associate professor, said these diseases led to yield reductions of 3% to 6% per year even prior …
By Sarah Strauss The recent rising temperatures are a reminder that summer is approaching, and the beginning of the rainy season is a great time to start planting cover crops. If you are looking for a method to invest in your soil health, cover crops are one option. By definition, cover crops are planted to improve soil health and are …

Using steam and a low dose of herbicide helped control goat weed in citrus better than a higher dose of herbicide, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers found. Goat weed, which poses major challenges for citrus, is found throughout the Southeast — from Texas, east to South Carolina and south to Florida. “It produces many …
