By Jawwad A. Qureshi Citrus under protective screen (CUPS) is a novel system for large-scale citrus production in screen houses covered with a tightly woven mesh screen on all four sides and the roof. The primary goal of this shift from a traditional open orchard to a CUPS system is to protect citrus crops from huanglongbing (HLB) disease, which is …
Research and field trials have been fairly consistent in showing that trunk injection of oxytetracycline (OTC) will reduce the HLB-causing bacteria in citrus trees, resulting in improved yield and quality. But what happens to the Asian citrus psyllid (ACP) when it feeds on treated trees? The answer to that question is becoming clearer now from research conducted by the University …
Researcher Ute Albrecht on April 21 shared lessons learned from three years of oxytetracycline (OTC) trunk injection for HLB management in Florida. Albrecht is an associate professor with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) specializing in citrus plant physiology. She works at the Southwest Florida Research and Education Center. Albrecht reported on results of a …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have found three commercially available insect species that devour the eggs of the HLB-spreading Asian citrus psyllid. These natural predators could become an important new line of defense against the devastating citrus disease. This is particularly true for organic growers who have limited options to control the psyllid, said …
The Florida Citrus Growers’ Institute was held at South Florida College in Avon Park last week to share the latest research from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Besides hearing presentations, attendees had an opportunity to interact one-on-one with scientists at 21 learning stations covering topics like entomology, citrus breeding, weed control and soil nutrition. …
The Florida Citrus Show marked another successful event in March in Fort Pierce. The show provided attendees with a fun, informative day to learn about citrus and specialty crops while engaging with exhibitors during the tailgate-style trade show. CRAFT UPDATE Citrus Research and Field Trial (CRAFT) programs have been very popular with growers and have incentivized new citrus plantings across …
Citrus and specialty crop growers will have a great opportunity this summer to gather, learn and connect at the Citrus & Specialty Crop Expo. The event is set for Aug. 12–13 at the Caloosa Sound Convention Center in Fort Myers. The annual Expo brings together citrus and specialty crop producers for two days focused on practical education and valuable industry …
By Peter Chaires Nurseries and growers are continuously searching for suitable substitutes for Hamlin sweet orange to supply the early/mid-season orange juice market. Besides traditional sweet oranges, many new hybrids are in various stages of development. Some of these are likely to rise to the level of commercial viability in the orange-like category. Growers wanting to trial an orange-like hybrid …
More than 300,000 CRISPR-edited citrus trees are being planted this year that have shown great potential against citrus greening disease in test groves. CRISPR, which stands for clustered regularly interspaced short palindromic repeats, is a gene-editing technology to help citrus growers produce a crop amid the disease. The Florida citrus industry is eager to see how these trees will respond …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus breeders and geneticists Fred Gmitter and Jude Grosser recently received the rare Citrus Research and Education Center (CREC) Resident Professorship Award. The award has only been bestowed four other times in CREC’s 109-year history. The award recognizes careers that have brought distinction to the CREC through outstanding programs, important …
U.S. Rep. Scott Franklin recently led members of the Florida congressional delegation in urging the Environmental Protection Agency (EPA) to complete a timely, science-based review of emerging citrus rootstock technologies to combat huanglongbing (HLB) disease, also known as citrus greening. Florida’s citrus industry has faced steep declines due to HLB, compounded by recent hurricanes and freeze damage. Production has dropped …
By Davie Kadyampakeni, Alisheikh Atta and Muhammad Shahid Micronutrients are those nutrients not required in large quantities but are important for improved tree performance. In the era of huanglongbing (HLB), micronutrients such as manganese (Mn), zinc (Zn), boron (B), iron (Fe) and copper (Cu) have become very critical for optimal tree management. For example, B is known to help the …
By Davie Kadyampakeni, Jonas Pereira de Souza Junior, Edilaine Istéfani Franklin Traspadini, Shankar Shrestha and Alisheikh Atta Integrated nutrient management is critical for improved and sustainable citrus production. Typical practices include split fertilization applications, the use of leguminous cover crops and the incorporation of soil amendments. This article discusses the importance of using novel blends, including macronutrients and micronutrients, as …
Recent research showed that individual protective covers (IPCs) proved highly effective in reducing Asian citrus psyllid (ACP) populations and thereby preventing HLB infection in three mandarin cultivars. However, overall tree response varied. The research was published in the Journal of the American Society for Horticultural Science. The authors are Saoussen Ben-Abdallah, Susmita Gaire, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and …
