The lebbeck mealybug, also known as the hibiscus mealybug, is a pest that has recently become problematic for Florida citrus growers. Extension agent Lourdes Perez Cordero and entomologist Lauren Diepenbrock, both with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), recently reported on the pest. According to Cordero and Diepenbrock, the lebbeck mealybug feeds by piercing the …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus plant improvement team joined the All In For Citrus podcast to discuss new varieties and those in the breeding pipeline. Fred Gmitter, professor of horticultural sciences, Jude Grosser, professor of plant cell genetics, and John Chater, assistant professor of horticultural sciences, also discussed how HLB has impacted their …
Mixon family members were pioneers in the Florida blueberry industry. Brothers Jerry and Keith Mixon planted their first berries in 1993. Over the years, they grew their business and became worldwide marketers, eventually adding blackberries, raspberries and strawberries to their portfolio. BACK TO CITRUSIn 2011, they sold their berry business to the Dole Food Company. But the brothers still had …
By Sarah Strauss The recent rains are a good reminder that it’s time to start thinking about planting summer cover crops. Despite the name, cover crops are not plants that are harvested for profit. Instead, they are planted as an investment in soil health. Annual or perennial plants can be used as cover crops in citrus groves. But, if you …
Lukasz Stelinski for years has promoted saving money on HLB control by spraying for Asian citrus psyllids (ACP) only when their populations reach a certain threshold. The University of Florida Institute of Food and Agricultural Sciences professor still promotes that concept, but with a slightly new twist. TRUNK INJECTION SHOWING PROMISEIn a virtual seminar on April 25, Stelinski advised growers …
Some growers are taking a closer look at citrus under protective screen (CUPS), while others have already adopted the production system. CUPS has been proven to protect trees from HLB and hurricane damage. The May issue of Citrus Industry magazine features grower brothers who are early adopters of CUPS. Jerry and Keith Mixon have 150 acres of CUPS production in …
By Fernando Alferez Five years of University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) data in trials across the state have shown that individual protective covers (IPCs) are effective in preventing HLB until they are removed. This has been shown in sweet orange varieties such as Valencia and Hamlin. In these varieties, it has been demonstrated that the …
April was a busy month for citrus events with both the Citrus Growers’ Institute and the Florida Grower Citrus Show taking place. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), joined the All In For Citrus podcast to discuss the success of the two events. Both gatherings …
Researchers are offering a lebbeck mealybug detection workshop in Fort Pierce on April 25. The event will be held from 9 a.m. to noon at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC). Register for the meeting here. Lebbeck mealybug (Nipaecoccus viridis) is an invasive pest that can cost the …
Tripti Vashisth, University of Florida Institute of Food and Agricultural Sciences associate professor, has been leading the research on how plant growth regulators (PGRs) can improve the health of HLB-infected trees. She’s conducted extensive research on the use of gibberellic acid. But she has recently begun to study another hormone, cytokinin. She gave an update on this work during the …
Far from his roots in a small town in northwest China, Changying “Charlie” Li is now the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) artificial intelligence (AI) administrative coordinator. He’s also a professor of agricultural and biological engineering. Li joined UF/IFAS last year to focus on agricultural AI with research, teaching and administration appointments. He wants to …
By Alessandro Franco, Faisal Shahzad and Tripti Vashisth Gibberellic acid (GA) is one of the most commonly used plant growth regulators which affects flowering, fruit and vegetative growth. Multiple monthly GA foliar applications have reduced preharvest fruit drop and increased yield in huanglongbing (HLB)-affected sweet oranges. The potential impact of these findings is huge for commercial citrus production. However, there …
By Fernando Alferez and Muhammad A. Shahid Brassinosteroids (BRs) are a natural group of hormones that regulate physiological and biochemical attributes that include seed germination, flower development, root formation and resistance to various abiotic and biotic stresses. BRs have shown promise in reducing pests and diseases in a wide range of plants, including citrus. A commercial formulation of BRs has …
The reinvigorated Florida Grower Citrus Show was a crowd-pleaser in its first year hosted by AgNet Media. The annual event was relocated to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture (USDA) facilities in Fort Pierce. It was streamlined from a two-day format to a one-day event. The show brought together exhibitors who …
Tripti Vashisth, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor, joined the March episode of the All In For Citrus podcast to discuss a new smartphone application growers will be able to use soon to measure tree health. Plant growth regulators like gibberellic acid, 2,4-D and brassinosteroids have demonstrated the ability to improve tree health and …
By Rhuanito S. Ferrarezi and Mark A. Ritenour Citrus under protective screen (CUPS) is a modern production system that excludes the Asian citrus psyllid and, consequently, the devastating disease citrus greening (huanglongbing or HLB) from plants cultivated in screenhouses. A recent study investigated the effect of different irrigation management strategies on fruit yield and quality of grapefruit grown in CUPS. …
By Xixuan Tang, Yu Wang, Fred Gmitter and Jude Grosser Citrus fruits and juices are commonly consumed worldwide due to their health benefits and flavor. However, recent trends in reducing carbohydrate intake have raised concerns from consumers about citrus products because of their relatively high levels of sugar content. This concern discourages repeat purchasing and consumption of citrus fruits and …
Florida researcher Ute Albrecht shared information about citrus tree roots at the recent Georgia Citrus Association annual conference. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor specializing in plant physiology discussed rootstocks and soils, suggested transplanting tips and touched briefly on freeze tolerance. Albrecht works at the UF/IFAS Southwest Florida Research and Education Center in …
The Florida Citrus Growers’ Institute, presented by the University of Florida Institute of Food and Agricultural Sciences, was held in Avon Park on April 4. The annual educational event drew a good crowd of growers and allied industry.
